Nymphs turn a dark brown, and the common name "six spotted cockroach" refers to six yellow spots along the sides of the nymph. Adults of both genders have wings but do not fly. They grow to approximately 6.4 cm (2.5 in) in length. Males are generally smaller than females, with longer wings, and a small rear sternite compared to females.
Blattodea is an order of insects that contains cockroaches and termites. [3] 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. [4]
The primary food sources for many "bookworms" are the leather or cloth bindings of a book, the glue used in the binding process, or molds and fungi that grow on or inside books. When the pages themselves are attacked, a gradual encroachment across the surface of one page or a small number of pages is typical, rather than the boring of holes ...
Immature cockroaches emerge from egg cases in 6–8 weeks and require 6–12 months to mature. After hatching, the nymphs feed and undergo a series of 13 moultings (or ecdysis). Adult cockroaches can live up to an additional year, during which females produce an average of 150 young. The American cockroach reproductive cycle can last up to 600 ...
An annual event could include Northern Hemisphere birds migrating south for the winter, or wildebeest migrating annually for seasonal grazing. A major habitat change could include young Atlantic salmon or sea lamprey leaving the river of their birth when they have reached a few inches in size.
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
Insects such as cockroaches thrive in warm environments, so they tend to more prevalent during the spring and summer months as the weather heats up, ...
The German cockroach (Blattella germanica), colloquially known as the croton bug, is a species of small cockroach, typically about 1.1 to 1.6 cm (0.43 to 0.63 in) [1] [2] long. In color it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of ...
