Belongs within: Phasmatodea. The Phylliinae include the leaf insects, characterised by having the abdominal terga and sterna dilated to mimic leaves. Living Phylliinae also have the tergal thorn pads reduced or absent, the fore femora straight, and the cerci dorsoventrally flattened. The fossil Eophyllium messelensis from the Eocene Messel Formation of Germany retains terete cerci… Continue reading Phylliinae

Belongs within: Tettigonioidea. The Listroscelidinae are a group of carnivorous katydids that are most diverse in the South American tropics and the Indo-Malayan region. They are distinguished by a series of long, curved spines on the fore tibiae that may be used in capturing prey (Rentz 1996). Characters (from Rentz 1996): Fastigium of vertex narrow,… Continue reading Listroscelidinae


Belongs within: Blattaria. The Polyzosteriinae are commonly flightless cockroaches, many of which produce foul-smelling defensive chemicals. Diurnal species are often strikingly coloured whereas nocturnal species are more usually black or brownish. Members of the tribe Methanini are fully winged or possess short, quadrate tegmina and vestigial hind wings, whereas Polyzosteriini are completely wingless or possess… Continue reading Polyzosteriinae


Belongs within: Blattaria.Contains: Ischnoptera, Parcoblattini. The Blattellidae are a diverse group of small to medium-sized, mostly fast-running cockroaches. A small number of species have become cosmopolitan domestic pests, including the German cockroach Blattella germanica and the brown-banded cockroach Supella longipalpa. Characters (from Roth 1991): Size usually small to medium; antennae longer than half body length.… Continue reading Blattellidae


Belongs within: Plecoptera. The name Grypopterygomorpha was used by Sinitshenkova (2002) for a clade of stoneflies including the modern Antarctoperlaria and its fossil relatives. They are characterised by wings with abundant cross-veins and the presence of both thoracic and abdominal gills in nymphs. Modern Antarctoperlaria are restricted to the Southern Hemisphere but stem grypopterygomorphs were… Continue reading Grypopterygomorpha

Belongs within: Neodermaptera. The Eudermaptera are a clade of earwigs characterised by the reduction of the male genitalia to a single penal lobe and single virga, and having the expanded regions of the anal and intercalary veins distinctly separated (Grimaldi & Engel 2005). In members of the families Chelisochidae and Forficulidae, the second segment of… Continue reading Eudermaptera


Belongs within: Apohaglida.Contains: Gryllinae, Nemobiinae, Eneopterinae, Oecanthinae, Gryllotalpinae, Mogoplistinae, Anaxipha, Trigonidium, Laupala. The Grylloidea include the crickets, a mostly dorsoventrally flattened, terrestrial group of orthopterans that are usually omnivorous. Their fore wings have a fan-like pleating intercalary triangle, and veins RA, RS and 1MA1 are fused completely or at least in part (Gorochov & Rasnitsyn… Continue reading Grylloidea


Belongs within: Grylloidea.Contains: Gryllus. The Gryllinae, field crickets and house crickets, include the most familiar members of the cricket family. Some species, such as the tropical house cricket Gryllodes sigillatus, have become abundant worldwide in association with human activity. The black field crickets of the genus Teleogryllus may be serious pasture pests in parts of… Continue reading Gryllinae
