Blattodea. Blattodea is an order of insects that contains cockroaches and termites. [1] Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. [2] The Blattodea and the mantis (order Mantodea) are ...
The Florida woods cockroach (Eurycotis floridana) is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in).

The Pennsylvania wood cockroach has three developmental stages: egg, nymph, and adult. Eggs are laid in egg capsules, produced during the warm months and deposited behind the loose bark of dead trees, fallen logs, or stumps. Egg capsules are yellowish brown and characteristically curved on both sides like a half moon.
