In recent years, there has been a surge of interest in relationships between tropi-cal plants and insects. The interest is driven by the related agendas of studying themfor their intrinsic scientific interest, and protecting tropical biodiversity through find-ing practical and non-destructive ways to use it. The latter agenda is exemplified bythe biochemical prospecting programs recently started in several areas of the world(Reid et al. 1993).

sections of the tropical insect fauna are still unusable as subjects of insect-plant re-search because that first step of linking plant and insect taxa has been largely ne-glected. In-depth studies of plant-insect interactions have focused on temperate zoneinsects and on a few relatively well known tropical groups (e.g., Lepidoptera). Only asmall percentage of the fauna of tropical herbivores has been similarly studied.

The family Chrysomelidae (Coleoptera), or leaf beetles, is a natural subject forstudying plant-insect and inter-herbivore interactions (Strauss 1988). Of the esti-mated 37,000 species, world-wide, in this family, almost all, as far as we know, areherbivores or seed predators. However, for about 70% of the described species, we donot have records of host plants. Most of the known host plant records are Holarctic(Jolivet 1988b). For Neotropical Chrysomelidae other than Bruchinae, the most spe-cific information treats economically important species (e.g., King & Saunders 1984,Ostmark 1975, Jolivet 1979, Hilje et al. 1991). However, a review of known host plantsof the tortoise beetles (Cassidinae) of Panama was recently published by Windsor etal. (1992); Moldenke (1971) listed host plants for some Mexican Chrysomelidae, andAnaya (1989) reviewed the known host plants of North and Central American Chry-somelinae. Jolivet, in a series of papers (1977, 1978, 1982, 1987a, 1987b, 1988a, 1991;Jolivet et al. 1986) and in a recent book (Jolivet & Hawkeswood 1995) summarizedcurrent host plant data on a world level for the Chrysomelidae. However, in much ofthis literature, beetle species are usually identified only to genus and their plant hostsonly to family. A few field studies have documented significant attacks by chry-somelids on plants in Central American ecosystems (e.g., Rockwood 1974, Memmottet al. 1993), and some detailed field and laboratory studies have been undertaken forseveral Neotropical species (Bach 1986, Begossi & Benson 1988, Buzzi & Winder1986, Hsiao 1988, Strong 1977a,b). Apart from these ecological studies of specificchrysomelids, many of the published host plant records are of dubious value, statingmerely that beetle X was taken on plant Y (or, all too often, “genus X feeds on plantgenus Y”). A further problem, also noted by Furth (1985), is that a large proportion ofsuch records are buried in taxonomic monographs and regional studies (e.g., Bechyné& Bechyné 1975) and accessible only by reading these studies in their entirety. Muchmore data on a much broader spectrum of chrysomelid taxa will have to be accumu-lated and made available before any credible generalizations about the nature of leafbeetle-plant interactions can be made.

In this paper, we present feeding records of adults and larvae for 137 species ofCosta Rican Chrysomelidae, representing 7 subfamilies and 92 genera. The majorityof these observations were made by the senior author during a six-month sabbaticalat Costa Rica’s Instituto Nacional de Biodiversidad (INBio) in 1991, and by the juniorauthor during the years 1978 to 1995 as a byproduct of an on-going intensive study ofthe caterpillars of the dry forests of Sector Santa Rosa of the Guanacaste Conserva-tion Area (Janzen 1993, Janzen & Gauld 1996). Our records include results from di-rect observations of free-living feeding, feeding tests, and field associations. We haveomitted many records where a single beetle was seen or collected on a plant, except fora few cases where the beetle was seen actively feeding.

Beetles were identified by the senior author (Criocerinae, Cryptocephalinae, Lam-prosominae, Eumolpinae) and the following specialists: Catherine N. Duckett (Uni-versity of Puerto Rico, Alticini), Vilma Savini P. (Universidad Central de Venezuela,Alticini), David G. Furth (U.S. Natural History Museum, Alticini), Shawn M. Clark(West Virginia Department of Agriculture, Galerucini), Charles L. Staines (MarylandDepartment of Plant Protection, Hispini), and Edward G. Riley (Texas A&M Univer-sity, Cassidini). Plants were identified by the authors and Quirico Jiménez (INBio),Nelson Zamora (INBio), and Pablo Sanchez (Museo Nacional de Costa Rica).

Our data are organized into a table with three supplementary appendices. Table 1lists observations by chrysomelid taxon, gives field data in summary form, and listsvoucher specimens. Appendix 1 is a key to plant family name abbreviations. Appendix2 gives the full localities for locality codes used in Table 1. Appendix 3 gives miscella-neous field observations, as well as relevant literature citations for many of the chry-somelid taxa. In Table 1 we have followed the higher classification of Reid (1995)which reduces several well-known subfamilies to tribal status and confirms earlieropinions (eg. Crowson 1955, Lawrence 1982) that Bruchidae, or seed weevils, are asubfamily of Chrysomelidae. Bruchinae are not included in this report; for informa-tion on their host associations, see Janzen (1980a), Johnson (1990), and literature ci-tations therein. While not all workers fully agree with all aspects of Reid’sclassification, it represents the latest and most comprehensive phylogenetic arrange-ment of the Chrysomelidae. For differing views, see Kingsolver (1995), Verma & Sax-ena (1996), and Reid (1996).

Explanation of Table 1Leaf Beetle

Scientific names follow Wilcox (1983) and Flowers (1996). In a few cases, approxi-mate species identifications are indicated by “nr.” before the species name: e.g.,

Pla-giodera

nr.

uniformis

. In some cases only generic identifications were possible, anddistinct morphospecies are numbered as such.

Plant

Names follow current usage in the Costa Rica National Herbarium and in the bot-any department at INBio. In cases where species identification is approximate, theterm “cf.” is used (e.g.,

Solanum

cf.

torvum

).

Plant Family

Classification follows the listings of the

Flora of Costa Rica

by the Missouri Botan-ical Garden and INBio, viewable on the World Wide Web at

http://cissus.mobot.org/manual.plantas/lista.html

. Families are coded by initial letters of their familynames. See Appendix 1 for full listing.

Stage

A, adult; L, larva; P, pupa

Locality

See Appendix 2 for full locality data.

Date

Date of initial collection is given in cases where beetles were reared from larvae orheld for testing.

Collectors

DHJ&WH: Daniel H. Janzen & Winnie HallwachsRWF: R. W. FlowersNames of other collectors are given as they appear on voucher data labels.

Score

This is an attempt to objectively communicate our level of confidence that an ob-served association involved actual feeding by the chrysomelid. 6 Chrysomelids were observed in the field actually eating plant material.5 Chrysomelids fed on plant when confined.4 10 or more chrysomelids were collected from a plant and feeding damage that

could reasonably be attributed to the beetles was present.3 Five to nine chrysomelids were collected from a plant and feeding damage that

could reasonably be attributed to the beetles was present,

or

10 or more chry-somelids were collected from a plant but obvious feeding damage attributable tothe beetles was not present.

2 Two to four chrysomelids were collected from a plant and feeding damage thatcould reasonably be attributed to the beetles was present,

or

five to nine chry-somelids were collected from a plant but obvious feeding damage attributable tothe beetles was not present.

1 Two to four chrysomelids were collected from a plant but no noticeable feedingdamage was observed.

Number (No.)

Number of vouchered specimens. In general, one feeding record equals onevoucher; the few exceptions are mentioned in the Note column.

Voucher

Specimens collected by the senior author have voucher codes in the form “(Collec-tion No.)-RWF(Year)” and are deposited in INBio. Those collected by the junior authorhave codes in the form “(Year)-SRNP-(Number)” and are nominally specimens of IN-Bio but are on temporary loan to the University of Pennsylvania.

Note

These are numbered consecutively and appear in Appendix 3.

Appendix 2. Localities

Localities cited in Table 1 are listed on an approximate north-south gradient. Thefirst letter of each locality code corresponds to the first letter of its province. Localitiesin the Area de Conservación Guanacaste also include Lambert Coordinates in paren-theses. Lambert Coordinates are used in Costa Rica in preference to latitude-longi-tude because the 1:50,000 topo sheets are gridded with Lambert Coordinates and,being metric, Lambert positions are easier to use.

ISCUSSION

The data presented in these tables represent only the beginnings of the task ofworking out host plant relationships for the Central American Chrysomelidae. Ourdata cover less than 7% of the estimated 2000 chrysomelid species present in CostaRica alone (Flowers, unpublished data). In some cases, our data confirmed previouslypublished relationships between chrysomelid genera and host plant families (summa-rized in Jolivet & Hawkeswood 1995); 30 of our records represent host plant familyrange extensions, and 19 records are for chrysomelid genera in which, apparently, nohost plants have been recorded previously.

Most previously published host plant studies for the Neotropical Chrysomelidae(aside from focused studies on specific taxonomic groups, (e.g., Bach 1986; Begossi &Benson 1988; Windsor 1986) make no distinctions between accidental or casual asso-ciations of plant and beetle and true host relationships. The dangers in not makingthese distinctions have been demonstrated to us on several occasions when we foundchrysomelid species that move off their food plants for resting or defecating. An exam-ple is

Omophoeta simulans

(Alticini, see Table 1), a group of which was first observedsitting on leaves of a

Luehea

sapling (Tiliaceae). Although large numbers of beetleswere on the

Luehea

, and their frass was also evident on these leaves, closer inspectionrevealed that no feeding was taking place on the

Luehea

and that the true food plant(

Evolvulus nummularis

; Convolvulaceae) was growing beneath the shrub. Similarwarnings about possible confusion of Alticini food plants due to the beetle’s mobilityhave been given by Hawkeswood and Furth (1994). Nevertheless, collection recordscan still provide useful information—for many taxa opportunistic collecting has pro-vided the only information we have on possible host plants—if their limitations areclearly acknowledged. For our data we have included a “reliability scale” to roughlymeasure our confidence that a given association represents a true chrysomelid-hostplant relationship. While ecological studies of narrow groups of chrysomelids orplants will always provide the most unambiguous data on feeding requirements, re-cent emphasis on and support for inventory collecting can rapidly increase knowledgeof the feeding habits of a broad range of chrysomelids, if observations are qualified insome manner.

We intend to continue expanding on the present work, and we encourage other col-lectors of Chrysomelidae to record, categorize and publish the plant associations theyobserve. Rapidly expanding our knowledge of chrysomelid-plant interactions is im-portant for two reasons. On the practical side, knowing host plants for more chry-somelid species will facilitate programs in chemical prospecting which are currentlyfocused on plants. When a family of plants is being surveyed for active chemicals, theinsects feeding on those plants represent another level of chemical derivatives avail-able for screening. The phytophagous insect may produce novel chemical varietieswhich cannot be synthesized directly from the host plant.

A second area where more host plant data are needed is in the testing of hypothe-ses of the evolution of host plant selection. At present there are two competing theo-ries of what chiefly influences this evolution: phylogenetic and ecological mediation.Phylogenetic mediation (cospeciation) postulates that most cases of herbivory arisefrom cospeciation or parallel descent. This theory has become a popular explanationof host plant selection, under the name “coevolution” (though we caution the readerthat this is not the original meaning of the word, see Janzen 1980b). Phylogenetic me-diation has been demonstrated in the Chrysomelidae for

Phyllobrotica

species (Gal-erucinae) and their hosts in the Lamiales (Farrell and Mitter 1990). However, theirstudy represents one of the few documented examples of coevolution (Anderson 1993).

The alternative hypothesis is that ecological mediation (colonization and hosttransfer) is the primary explanation for current host associations. In cases of ecologi-cal mediation, phylogenies of herbivores and host plants are not congruent, and hostshifts are not necessarily between sister taxa of plants Anderson (1993). In a surveyof the Curculioninae (Curculionidae), Anderson (1993) found that in taxa where sys-tematics and plant associations were reasonably well known, evidence for cospecia-tion of plant and insect taxa is lacking, and ecological mediation appeared to be therule. However, like the Chrysomelidae, the majority of curculionine taxa lack any hostplant data. Until host plants are known for a much larger proportion of phytophagousinsect taxa, speculations on the evolution of host plant selection by insects will con-tinue to be based on small subsets of the phytophagous insect universe.

Flowers & Janzen: Chrysomelid Feeding Records 363

Appendix 3—Notes to Table 1.

1. These beetles were sitting on heavily eaten leaves, 1.5 m above ground.2. Additional specimens were observed at time of collection, and C. Chavez reported

seeing this species frequently on the same host plant.3. This species was tested on the host plant. Jolivet (1978) gave Asteraceae, Mimo-

saceae, Ericaceae and Fagaceae as other host plant families of this genus. 4. This species was found feeding at shoot tips of its host plant.5. The host plant is an abundant roadside weed on the entrance road in Sector

Santa Rosa and elsewhere in this sector. Beetles have been collected both in therainy and dry seasons. The larvae make cone-shaped cases, apparently utilizinghairs of the host’s leaves. Moldenke (1971) listed both Malvaceae and Convolvu-laceae as host plant families for this species.

6. The vouchers were collected from a swarm of this species feeding on the low bushin dense dry forest. The intense feeding and mating activity was similar to thatobserved in other Clytrinae (Flowers et al. 1994, Moldenke 1971). Jolivet (1978)lists Mimosaceae as the predominant host for this genus.

7. The beetle was seen eating bark of new stems. Monrós (1949) and Jolivet (1978)described bark feeding by other members of this genus.

8. This species was very abundant on the leaves of its host at several regeneratingpasture sites in 1991. This cosmopolitan genus has been recorded from Arali-aceae from the Palearctic and from Myrtaceae from Puerto Rico (Jolivet 1978).

9. In 1991 this species was very abundant in the pastures and open areas after theonset of the summer rains. Individuals were also collected on other pastureshrubs. The collection of Jan Bechyné in Maracay Venezuela contains severalspecimens of this species collected in El Salvador and bearing the (apparently)manuscript name "saltator". The only other host record for this genus is Theo-broma cacao L. (Sterculeaceae) for an unidentified species (Jolivet 1987b).

10. Jolivet (1987b) stated that all host observations of the genus Chalcophana havebeen Asteraceae.

11. Although only one voucher was preserved, numerous adults were observed, andseveral were tested on the leaves of the plant host. Jolivet (1987b) noted that thisgenus is both cosmopolitan and polyphagous.

12. Adults were feeding at night on very new expanding leaves of a 1.5 m shoot atbase of tree. Jolivet (1987b) stated that the only reliable feeding records for thisgenus are from Fabaceae.

13. The only host records in the literature for Percolaspis are from Poaceae and Theo-broma cacao (Jolivet 1987b).

14. This species has been found feeding on several species of Rubiaceae. Adults areagile leapers when disturbed. Jolivet (1987b) gave a single record for this genus:Persea (Lauraceae) for a Cuban Phanaeta.

15. Adults of this genus were found on new foliage and in some years defoliated theirhosts.

16. This species was very common feeding on various species of Melastomataceae.Jolivet (1987b) described Typophorus as polyphagous but does not list any Melas-tomataceae among its host plants.

17. The voucher is one of many collected, seen and reared at Estación Pitilla and SanGabriel on various species of Solanum.

18. Larvae skeletonize host plant leaves. This species extensively defoliates its hostduring some years. Literature records for New World Plagiodera are limited toSalix, Populus (Salicaceae), Croton (Euphorbiaceae), and Lueha (Tiliaceae); how-

ever, species in the Philippines and India have been reported on Xylosoma andFlacourtia (Flacourtiaceae) (Jolivet & Hawkeswood 1995).

19. This is the most commonly collected of the Costa Rican species of Platyphora.During one feeding test, two very small larvae were observed in the plastic bagwhich up till then held a single female, suggesting that Platyphora bicolor is vi-viparous. Schroder et al. (1994) described the biology of the viviparous Platy-phora quadrisignata (Germar) from southern Brazil.

20. Adults and larvae were frequently found feeding on host plant throughout the1991 rainy season. Apparently, our observations represent the only known hostplant data for Stilodes.

21. A group was followed from egg to adult. Larvae feed and rest on underside ofleaves. Pupation takes place in leaf litter.

22. Larvae are sooty black, covered with branched hair-like projections, and with redheads. Pupae are yellow. This chrysomelid was parasitized by Myopharous (Ta-chinidae: Diptera).

23. In 1991 this beetle caused a major defoliation of its host plant, a pioneer speciesin cleared pastures.

24. The host plant of this galerucine was found growing along the edge of a smallpatch of forest.

25. The host plant was a low understory tree in tropical dry forest.26. This galerucine was seen on several occasions feeding on young leaves of its host

plant. This genus has been recorded from Acacia (Fabaceae) in the USA (Jolivet1987a).

27. A large group of these Masurius (which may represent more than one species)was found feeding on the two host plants growing within a few yards or eachother along a trail in montane forest.

28. This and the following species were reared to adult.29. In addition to the voucher specimens, other specimens were collected two years

earlier on the same host plant.30. RWF has observed adults of this species every year since 1989 defoliating basal

shoots of a tree growing in front of the main administration building at the Uni-versity of Costa Rica. Jolivet (1987a) listed Cordia and Lantana (Verbenaceae) ashosts of this genus.

31. RWF observed on individual at night eating a hole in the middle of a leaf of theIpomoea host plant.

32. In both cases, beetles were observed feeding on the host plant. Jolivet (1991)listed Labiaceae and Verbenaceae as probable hosts for this genus and notedother citations of Lauraceae, Buddlejaceae, Asteraceae, Umbelliferae, Sterculi-aceae, and Fabaceae.

33. In addition to the vouchered specimen from Byrsonima crassifolia, this specieswas abundant on this host plant at Estacion Maritza (G4) in 1991.

34. Unlike many other chrysomelids which were found associated only with youngfoliage, A. salvadorense was found actively feeding late in the rainy season onolder leaves.

35. A large group of these beetles was found on a broken stalk of the host plant, feed-ing on sap and milky latex. The host plant was growing in the shaded understoryof montane forest.

36. Adults were reared from larvae feeding on the host plant.37. Jolivet (1991) listed Samanea (Fabaceae/pap.) as a host of this genus.38. Jolivet (1991) cited Theobroma and Tecoma (Bignoniaceae) as other known host

plants of this alticine genus.

39. Both this and the following host plant were growing close together in a mixedstand next to a road.

40. The host plant, growing in a wet depression in a cleared area, sustained heavyfeeding damage from this alticine in 1991. Jolivet (1991) listed Cleome, Solanum,Beta (Chenopodiaceae), Labiaceae, Cordia, and Adiantum (Adiantaceae) as hostplants of Leptophysa.

41. These beetles were swept from a tree that showed heavy feeding damage to theleaves. No active feeding was observed, but this collection was made during anabnormal dry spell during what was supposed to be the wet season.

42. This Longitarsus is a flightless species.43. Field observations by DHJ indicate that the adult appears on the host plant to

oviposit; larvae are free living and cut islands out of leaf margin.44. The host plant is a small prostrate weed. The beetles were first observed resting

and defecating on a shrub of Luehea (Tiliaceae) which grew over the Evolvulus.When no feeding damage on the Luehea was seen, despite the beetle activity, awider search revealed the true host plant.

45. These small pinkish-orange flea beetles were observed feeding on newly expand-ing leaves (which are also reddish to pinkish orange) of their ericaceous hosts.

46. This alticine was collected abundantly from a very dense stand of its host plant.In 1994 it was found equally abundantly in the same stand of plants.

47. RWF has observed this species over several years, actively feeding on Euphorbi-aceae even during the dry season in quite arid habitats.

48. These represent five different morphospecies of Syphrea collected on variousplants.

49. This species feeds by scraping pits in the expanding leaves of this host plant. Thefollowing plant record may be an alternate dry season food source.

50. Huge numbers of this species were found defoliating the host plant during thevoucher year. In 1991, on the other hand, no specimens were found and no dam-age to the host was apparent. This is the species called Oedionychis sp. in Rock-wood (1974). Bechyné (1955) restricted the definition of true Oedionychis to asmall group of flightless Mediterranean flea beetles. New World species formerlyin Oedionychis are now placed in Walterianella, Alagoasa and other genera.

51. Jolivet (1991) listed Venezuelan records of Gardinia (Rubiaceae) and Tabebuia(Bignoniaceae) for this genus.

52. The genus Cephaloleia is well known from various species of Heliconia and otherZingiberales (Strong 1977a,b). This species was regularly encountered in rolled-up terminal leaves of Costus at this and other localities.

53. This hispine was very abundant in a dense stand of grass growing on a river sand bar.54. A large number of these hispines were feeding on and heavily damaging leaves

of a shrub of its host growing along the bank of a river in deep shade.55. These cassids have black larvae with long black caudal brushes; the pupae have

a creamy white thorax. Adults were reared.56. Windsor et al. (1992) gave Ipomoea lindenii Mart. & Gal. as host plant for true

C. egregia.57. This species periodically defoliates its host.58. Feeding on young leaves of Alibertia was seen; some feeding damage was also

seen on the two bignoniaceous plants as well.59. The cassid caused a major defoliation in 1979, but has been rare since. The 1991

record was from a single tree growing by the seashore and heavily damaged by agroup of the cassids. Jolivet (1988a) also listed Tabebuia and other Bignoniaceaeas hosts for this genus.

60. These records are of beetles aestivating in the dry season; see Flowers (1991) formore details on this behavior. Windsor et al. (1992) listed several species of Cor-dia as the true host plants of this species.

61. The host plant was an understory plant in a pine plantation. Jolivet (1988a) alsolisted Hyptis (Labiaceae) as a host plant for this genus.

62. The record from Bursera simaruba is for beetles hiding under bark plates duringthe dry season. Jolivet (1988a) listed Phaseolus (Fabaceae) and Passiflora (Pas-sifloraceae) for this genus.

63. In 1991 this species was common during the rainy season. A colony at the Ad-ministration Area in Sector Santa Rosa (G14) was followed for several months,during which time predatory pentatomids were observed resting on foliage abovethe cassids, and occasionally descending to feed on them.

64. Windsor et al. (1992) listed Cordia spinescens for a P. nr. alutacea from Panama.65. Windsor et al. (1992) also list Solanum seaforthianum Andr. and Physalis cor-
