Polyphagidae
Corydiidae, previously known as Polyphagidae, is a family of the order Blattodea (cockroaches). Many are known as sand cockroaches. The family is divided into five subfamilies, comprising some 40 genera. One prominent species is the desert cockroach, '' Arenivaga investigata''.

Cockroach
Cockroaches (or roaches) are a Paraphyly, paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as Pest (organism), pests. The cockroaches are an ancient group, with their ancestors, known as "Roachoid, roachoids", originating during the Carboniferous period, some 320 million years ago. Those early ancestors, however, lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects lacking special adaptations (such as the sucking Insect mouthparts, mouthparts of aphids and other Hemiptera, true bugs); they have chewing mouthparts and are probably among the most primitive of living Neopteran insects. They are common and hardy insects capable of tolerating a wide range of Köppen climate classification, climates, from Arctic cold to Tropics, tropical heat. Tropical cockroaches are often much larg ...

Blattodea
Blattodea is an order of insects that contains cockroaches and termites. 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. The Blattodea and the mantis (order Mantodea) are now all considered part of the superorder Dictyoptera. 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. Within the colony, termites have a caste system, with a pair of mature reproductives, the king and the queen, and numerous sterile workers and soldiers. Cockroaches are not colonial but do have a tendency to aggregate and may be considered pre-social, as all adults are capable of breeding. Other simil ...

Saint Petersburg Zoological Museum
The Zoological Museum of the Zoological Institute of the Russian Academy of Sciences is a Russian museum devoted to zoology. It is located in Saint Petersburg, on Universitetskaya Embankment. It is one of the ten largest nature history museums in the world. Peter the Great's Kunstkamera collections included zoological specimens. In 1724, the museum became a part of the Russian Academy of Sciences. A printed catalogue of the contents was published in 1742. It listed the zoology, botany, geology and anthropology specimens and contained an album of etchings of the building and plan of some of its parts. In 1766, Peter Simon Pallas, a member of the Russian Academy of Sciences, was appointed curator of Zoology. In 1832, the zoological collection was split from the Kunstkamera and, in 1896, moved nearby to its present location in the former southern warehouse of the Saint Petersburg bourse (constructed in 1826-1832). In 1931, the Zoological Institute was established within the Acad ...
