Insect Camouflage & Coloration

Cryptic coloration, body shape, and other adaptations are often common place in the insect world.  While most of us are familiar with walking sticks looking like tree or plant stems a variety of other insects have unique strategies for survival.  One group of insects that often can have rather grisly way of camouflaging themselves are assassin bugs.  The assassin bug, Acanthaspis petax, has the perhaps one of the coolest body armors in the natural world.  What is it?  A. petax uses the dead carcasses of ant prey to cover its body.  Research completed in 2007 found this corpse filled defense helps repel spiders from preying on them (Stromberg, 2012).

Another unique way of protecting yourself in the insect world is to resemble something big and tough, such as a snake. A number of caterpillars of moths and butterflies mimic the appearance of snakes to deter predators.  One such caterpillar is the spicebush swallowtail butterfly larva (Beiser Field Station, 2008).
