Phyllum Arthropoda
• Exoskeleton• Segmented legs & body• Bilateral symmetry • Ventral nerve cord • Dorsal blood pump
Class Arachnida (arachnids): spiders, scorpions, ticks, mites, etc.Arachnids possess: 2 body segments - cephalothorax and abdomen 8 legs; 1 pair of chelicerae; no antennae
Class Chilopoda (centipedes)Chilipods possess: many body segments 1 pair of legs per body segment; 1 pair of antennae 1st pair of legs modified into venomous fangs
Class Diplopoda (millipedes)Diplopods possess: Many body segments 2 pair of legs per body segment; 1 pair of antennae
Class Crustacea (crustaceans): crabs, shrimp, barnacles, sowbugs, etc.Crustaceans possess: Several body segments - head, thorax and abdomen Segments may be fused; Varied number of legs 2 pairs of antennae
Class Insecta (Insects); beetles, bugs, wasps, moths, flies, etc.Insects possess: 3 body segments 6 legs 1 pair of antennae Diverse modifications to appendages

Insect classification
Approx. 30 orders of insects
Classified by type of development type of mouthparts wings (number and placement)
Order Orthoptera
Simple developmentChewing mouthpartsTwo pairs of wings/ first set are thickened and
leather-like
Order Dermaptera
Short wing covers-second pair not always developed
Simple developmentChewing mouthpartsHave terminal forceps20 species in North America
•Complete development-larvae are caterpillars
•Larvae have chewing mouth parts
•Two pairs of wings, covered with scales
Order Lepidoptera
Order Coleoptera
•Complete development- larvae are grubs
•Chewing mouthparts larvae and adults
•Two pairs of wings-first hardened into
wing covers (elytra)
Order Diptera- Flies •Complete development-larvae are maggots•Chewing mouthparts in larvae/ variable in adults•Adults only have 1 pair of wings
Order Hymenoptera
•Complete development-larvae are maggot like•Chewing mouthparts in larvae•Two pairs of wings• both membrane-like hooked together to work as one
Order Ephemeroptera
• Delicate bodies with four wings (front pair much larger) many cross veins
• Mouth parts of the chewing type but rudimetary
• Incomplete development, aquatic larval stage
Order Odonata
Adults have 4 wings of equal size, membranous
Chewing mouthparts, well developed Incomplete development, aquatic larval
stage
Order Neuroptera
• Chewing and biting mouthparts• Feed on other insects and small
animals • Four wings, well veined• Complete metamorphosis
Order Trichoptera
• Soft bodied • Four membranous wings with numerous
longitudinal veins • Mouth parts rudimentary • Antennae and legs are long • Complete development
Order Thysanura
• Apterygota (no wings)• Ametabolous developement• Abdomen has 11 segments • Covered in scales
Order Mantodea
• Predatory insects closely related to roaches
• Front pair of legs are armed with strong spines to grasp prey
• Four wings, membranous with soft covering
• Incomplete development
Order Blattaria
• 4,000 species worldwide• Cursorial (adapted for running)• Wings are generally present though in
some they are much reduced • chewing mouthparts• Incomplete development
Order Isoptera
• Chewing mouthparts (modified in soldiers for nest defense)
• 2 equal wings present only in reproductive stage
• Incomplete development • Social insects
