Why are they called cockroaches?
Why Are They Called Cockroaches? The name cockroach comes from the Spanish term cucaracha, which derives from the Latin blatta, “an insect that shines the light.” It comes from the insect order Blattodea, which also includes termites.
What are the characteristics of Blattodea?
Blattodea are cursorial insects with the hind legs similar in shape and size to the middle legs; many species are extremely rapid runners. Some species lack wings; when wings are present, the forewings are modified into moderately sclerotized tegmina that protect the membranous hind wings.
How many species of Blattodea are there?
4,400 species
Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera. Termites are pale-coloured, soft-bodied eusocial insects that live in colonies, whereas cockroaches are darker-coloured (often brown), sclerotized, segmented insects.
What is the relationship between mantids and cockroaches?
Mantises and roaches are related because they’re in the same Superorder – Dictyoptera. The suborder Dictyoptera includes cockroaches and mantis. It’s believed now that termites (Isoptera) are included in the cockroach order (Blattodea).
Are Blattodea extinct?
Not extinctBlattodea / Extinction status
Are cockroaches Hemiptera?
Examples include cockroaches and psocids, both of which have longer, many-segmented antennae, and some beetles, but these have fully hardened forewings which do not overlap.
Is it a roach or a beetle?
Cockroaches have flat, oval-shaped bodies with long legs and antennae. Most beetles have shorter legs and antennae. Beetles have a hard exoskeleton and make a definite “crunch” when squashed.
Who named cockroach?
It is mentioned by Aristotle, saying that it sheds its skin; it is described as foul-smelling in Aristophanes’ play Peace; Euenus called it a pest of book collections, being “page-eating, destructive, black-bodied” in his Analect. Virgil named the cockroach “Lucifuga” (“one that avoids light”).
Are cockroaches female?
Male and female cockroaches can be identified by their body types and appendages. Females are usually larger than males (wider bodies) and have longer antennae. Their wings may not be functional and will lie dormant on their back. Males have long and broad wings, matched by their slender bodies.

Dictyoptera. Dictyoptera (from Greek δίκτυον diktyon “net” and πτερόν pteron “wing”) is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea ( termites and cockroaches together)) and the order Mantodea (mantises), along with one extinct order, the Alienoptera.
What are the closest living relatives of the Dictyoptera?
According to genetic evidence, the closest living relatives of the Dictyoptera are the phasmids and the enigmatic order Notoptera. If the Dictyoptera are considered a superorder these other orders might be included in it.
