TAXONOMY
PHYSICAL DESCRIPTION
They are cold-blooded, invertebrate animals. Their size ranges from 12mm. to 14mm. They have a brown thorax and head with
areas of dark greens, browns and bronzes. They have patterned elytra which are
leathery wing covers that protect their wings located beneath.
The patterns on these covers are symmetrical with a line running parallel to the pincers.
Physical Description Continued…
Their large eyes help them spot their prey. Then they move quickly to capture their prey
running after the prey on long slender legs. Their name comes from their ferocity as
hunters.They spot their prey with their large eyes and
then sprint to catch them, like tigers.
Speed
Aggressive and highly skilled predators, tiger beetles have been clocked as the fastest animal on earth.
If they were the size of a horse they’d probably be running 200 or 300 miles per hour.
In fact, they can run so fast that they stop being able to process the incoming visual input, becoming blind, and need to stop to reorient themselves.
Hunting Technique
When these speedy animals capture their prey, they grab it with their long, sword like mandibles, crush and tear the insect apart, and then spit up their saliva, which digests their prey even before they suck it up as a gooey stew.
The puritan tiger beetle is carnivorous and at least a third level consumer.
Their diet consists of small insects, flies and ants mainly.
Predators
Dragonflies and robber flies may eat adults. Flies and wasps threaten the larva by laying
parasitic eggs in larval burrows. If the fly and wasp eggs survive, the wasp
larva attach themselves to the beetle larva and eat them alive.
HABITAT Puritan tiger beetles are found in only two
places in the world the Chesapeake Bay and the Connecticut River.
This beetle requires sandy beaches along both fresh and brackish water such as rivers, streams and estuaries.
The beaches, often located at bends in the river, are generally dry, wide, and free of vegetation.
These beaches are also where the tiger beetle’s prey are found.
Environmental Biotic Factors
Flies, ants, and beach shrubbery.Flies and ants are its main prey and beach
shrubbery provides protection from beach predators.
Humans on the beach disrupt the beetle’s ability to mate.
Puritan tiger beetles are most active on the beach at the same time people are.
Environmental Abiotic Factors
Sand and fresh or brackish water are the basic abiotic factors.
The pollutants that pass through the water and debris forming natural dams or obstacles can affect this beetle.
Also man-made dams affect their place of habitat and may constrict waterways and flood their precious beaches.
Life Cycle
The Puritan tiger beetle’s life cycle is only 2 years long.
They spend about 96% of these 2 years as a larva.
They are larva for 22 months spending much of their lives buried in the sand.
The adults emerge anytime from late June to early August.
Life Cycle Continued…
The beetles go from eggs to larva and then molt several times to pupa, finally becoming adults.
This leaves them very little time as adults and little time to mate.
Mating and egg laying occurs in mid August.The females place their eggs one by one just
underneath the top layer of sand and then die.
