Eublaberus posticus, the orange head cockroach, is a species of cockroach native to Central and South America. [1]
Female individuals of E. posticus have been known to survive for up to 360 days on just water. [2] They mate just after hatching, once the wings have expanded but before the cuticle has hardened. Females have been known to kick at the intersexual junction during intercourse. [3]
Termites are eusocial insects that are classified at the taxonomic rank of infraorder Isoptera, or as epifamily Termitoidae within the order Blattodea. Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are the sister group to wood eating cockroaches of the genus Cryptocercus. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants.
The American cockroach is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. It is often misidentified as a palmetto bug.
The Florida woods cockroach or palmetto bug is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). When alarmed, adults can eject an extremely foul-smelling directional spray up to 1 m, which inspired several of its other common names: Florida skunk roach, Florida stinkroach, skunk cockroach, skunk roach, stinking cockroach, and stinkroach. Two other naming variations include Florida cockroach and Florida woods roach.
The oriental cockroach, also known as the waterbug or black beetle, is a large species of cockroach, adult males being 18–29 mm (0.71–1.14 in) and adult females being 20–27 mm (0.79–1.06 in). It is dark brown or black in color and has a glossy body. The female has a somewhat different appearance from the male, appearing to be wingless at a casual glance, but is brachypterous, having non-functional wings just below her head. She has a wider body than the male. The male has long wings, which cover three quarters of the abdomen and are brown in color, and has a narrower body. Both of them are flightless. The female oriental cockroach looks somewhat similar to the Florida woods cockroach and may be mistaken for it. Originally endemic to the Crimean Peninsula and the region around the Black Sea and the Caspian Sea, its distribution is now cosmopolitan.
The Cockroach is a small species of cockroach, typically about 1.1 to 1.6 cm long. In colour 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 the wings. Although B. germanica has wings, it can barely fly, although it may glide when disturbed. Of the few species of cockroach that are domestic pests, it probably is the most widely troublesome example. It is very closely related to the Asian cockroach, and to the casual observer, the two appear nearly identical and may be mistaken for each other. However, the Asian cockroach is attracted to light and can fly like a moth, while the German cockroach cannot.
The Surinam cockroach or greenhouse cockroach is a species of burrowing cockroach. It is a common plant pest endemic to the Indomalayan realm that has spread to tropical and into subtropical regions around the world, and in isolated populations to temperate climates where protective habitat such as greenhouses provide shelter for individuals inadvertently shipped in the soil of plants. Its populations are almost exclusively female, and it reproduces through parthenogenesis, having evolved several clonal strains from its sexual progenitor P. indicus.
The Australian cockroach is a common species of tropical cockroach, with a length of 23–35 mm (0.91–1.38 in). It is brown overall, with the tegmina having a conspicuous lateral pale stripe or margin, and the pronotum with a sharply contrasting pale or yellow margin. It is very similar in appearance to the American cockroach and may be easily mistaken for it. It is, however, slightly smaller than the American cockroach, and has a yellow margin on the thorax and yellow streaks at its sides near the wing base.
Parcoblatta fulvescens, the fulvous wood cockroach, is a species of cockroach endemic to the United States and possibly Canada that measures around 13 mm (0.5 in) long.
The Wongai ningaui, a common name of Ningaui ridei, is a tiny carnivorous marsupial native to the arid open grasslands of inland Australia. Their diet is mainly small insects, and occasionally larger prey such as spiders, grasshoppers and cockroaches, which they forage for at the ground and in clumps of spinifex. They have long and untidy fur, grey or gingery brown with longer black hairs, small ears, a narrow muzzle, and possess a partially prehensile tail and feet that allow them to climb. The population occurs sparsely across a wide area and common in favourable habitat, especially in years of good rainfall. Ningaui ridei was first described in 1975, one of two species of a new genus discovered amongst the poorly known mammals of the western regions of Australia.
Blattodea is an order of insects that contains cockroaches and termites. Formerly, the termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests an intimate relationship with the cockroaches, both cockroaches and termites having evolved from a common ancestor. The Blattodea and the mantises 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.
Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests.
Blaberus discoidalis, commonly known as the discoid cockroach, tropical cockroach, West Indian leaf cockroach, false death's head cockroach, Haitian cockroach, and drummer, is a cockroach native to Central America of the “giant cockroach” family, Blaberidae.
Blattoptera, or proto-cockroaches, is a name given to various "roachid" fossil insects related to cockroaches, mantises and termites, and of general cockroach-like appearance and possibly habit. The group is on the rank of an order, though being paraphyletic is most often given without formal taxonomic rank. Several alternative names have been suggested for this fossil group, including Blattodea, a name currently used for the group including the modern cockroaches as well as their fossil relatives.
The Dubia roach, also known as the orange-spotted roach, Guyana spotted roach, or Argentinian wood roach, is a medium-sized species of cockroach which grows to around 40–45 mm (1.6–1.8 in).
Cockroach racing is a club gambling activity which started in 1982 at the Story Bridge Hotel in Brisbane, Queensland, Australia. The event is held on 26 January, Australia Day, and is given the title "Australia Day Cockroach Races". This type of racing has spread to many parts of the world including the United States. In North America, cockroach racing has recently become a popular feature for money, prizes, or just for its entertainment value. It is held in exhibitions promoting entomology where the public and entomologists participate.
The Japanese cockroach, also known as the Yamato cockroach, is a cockroach native to Japan, adapted to cooler northern climates. It has a flexible univoltine or semivoltine lifecycle, depending on the timing of its hatching, and is unusual in being able to spend two winters as diapause nymphs before reaching maturity.
The Turkestan cockroach, also known as the rusty red cockroach, red runner cockroach or simply rusty red, red runner, or lat, is a primarily outdoor-dwelling cockroach native to an area from northern Africa to Central Asia. Adults measure around 3 cm (1.2 in) in length. Adult males are a brownish orange or red, are slender, and have long, yellowish wings which allow it to attract females and to glide. Adult females are dark brown to black, with cream-colored markings on the shield and a cream-colored stripe edging its wings; they are broader than males, and have short vestigial wings. Nymphs are brown in front, black on the rear, and are wingless.
Cariblatta lutea is a small species of cockroach native to the United States and other countries, measuring usually around 7 millimeters long as an adult and under 2 millimeters from head tip to abdomen tip at the 1st instar or hatchling. It consists of two subspecies, the small yellow cockroach, and the least yellow cockroach.
Parcoblatta lata, the broad wood cockroach, is a species of wood cockroach native to the United States. It is one of the largest species of wood cockroaches.
Lucihormetica verrucosa is a species of giant cockroach in the family Blaberidae, commonly known as the warty glowspot cockroach. It is native to Venezuela and Colombia.
