Gryllacrididae are a family of non-jumping insects in the suborder Ensifera occurring worldwide, known commonly as leaf-rolling crickets or raspy crickets. The family historically has been broadly defined to include what are presently several other families, such as Stenopelmatidae ("Jerusalem crickets") and Rhaphidophoridae ("camel crickets"), [1] now considered separate. As presently defined, the family contains two subfamilies: Gryllacridinae and Hyperbaeninae. [2] They are commonly wingless and nocturnal. In the daytime, most species rest in shelters made from folded leaves sewn with silk. Some species use silk to burrow in sand, earth or wood. [3] Raspy crickets evolved the ability to produce silk independently from other insects, but their silk has many convergent features to silkworm silk, being made of long, repetitive proteins with an extended beta-sheet structure. [4]
The Orthoptera Species File [2] lists two subfamilies:
Note: The genus Lezina of the subfamily Lezininae is now placed in the family Anostostomatidae.
Anostostomatidae is a family of insects in the order Orthoptera, widely distributed in the southern hemisphere. It is named Mimnermidae or Henicidae in some taxonomies, and common names include king crickets in Australia and South Africa, and wētā in New Zealand. Prominent members include the Parktown prawn of South Africa, and the giant wētā of New Zealand.
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave crickets, camel crickets, spider crickets, and sand treaders. Those occurring in New Zealand are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described.
Stenopelmatidae is a family of large, mostly flightless orthopterans that includes the Jerusalem crickets. Two genera: Ammopelmatus and the type genus Stenopelmatus are found in the New World. Oryctopus and Sia are Old World genera, and previously placed in their own subfamilies, but with the addition of new genera, current placement is as five tribes in the single subfamily Stenopelmatinae.
Trigonidiinae is a subfamily of insects in the order Orthoptera, suborder Ensifera, based on the type genus Trigonidium. They are often referred to as sword-tail crickets, winged bush crickets or trigs.
The Phaneropterinae, the sickle-bearing bush crickets or leaf katydids, are a subfamily of insects within the family Tettigoniidae. Nearly 2,060 species in 85 genera throughout the world are known. They are also known as false katydids or round-headed katydids.
Phalangopsinae, occasionally known as spider crickets, are a subfamily of crickets in the family Phalangopsidae. Members of Phalangopsinae are found worldwide in tropical and subtropical regions. Most species in the subfamily are nocturnal and can be found in rocky areas, near fallen wood, and the understory of forests. Some species are gregarious, gathering in large numbers.
Gryllacridinae is an Orthopteran subfamily in the family Gryllacrididae.
Larnaca is an Asian genus of Orthopterans, sometimes known as 'leaf-folding crickets', in the subfamily Gryllacridinae and tribe Gryllacridini. Species have been recorded from: southern China, Indochina and western Malesia.
Grylloidea is the superfamily of insects, in the order Orthoptera, known as crickets. It includes the "true crickets", scaly crickets, wood crickets and other families, some only known from fossils.
Capnogryllacris is a genus of leaf-rolling crickets in the subfamily Gryllacridinae and tribe Capnogryllacridini. Species are found in Far East and South Asia, which includes those previously placed in the obsolete genus Borneogryllacris.
Anabropsis is a genus of king crickets in the tribe Anabropsini. They are found tropical areas of the Americas, Africa and Asia.
Rhaphidophora is the type genus of camel crickets in the tribe Rhaphidophorini.
The Phalangopsidae are a recently reconstituted family of crickets, based on the type genus PhalangopsisServille, 1831 from South America. Priority for family-group names based on this genus dates from Blanchard's "Phalangopsites".
Gryllacris is a genus of Orthopterans, sometimes known as 'leaf-folding crickets' in the family Gryllacridinae. It is the type genus for the family, tribe Gryllacridini and its subfamily.
Hyperbaeninae is a subfamily of Orthopterans, sometimes known as 'leaf-folding crickets' in the family Gryllacrididae; Hyperbaenus ensifer is the type species. The known distribution includes tropical: central and southern America, Africa and mainland Asia to Australasia.
Paragryllacris is a genus of Australian Orthopterans, sometimes known as 'leaf-folding crickets' in the family Gryllacridinae, erected by the Swiss entomologist Carl Brunner von Wattenwyl in 1888. It is fairly typical for its tribe Paragryllacridini. However, in a large comparison of 650 insect species, Australian Raspy Crickets were found to be the insect with the strongest bite.
Phryganogryllacris is an Asian genus of Orthopterans, sometimes known as 'leaf-folding crickets', in the subfamily Gryllacridinae and tribe Phryganogryllacridini. Species have been recorded from: India, China, Indochina, Malesia, through to New Guinea.
Neanias is a genus of Orthopterans, sometimes known as 'leaf-folding crickets' in the subfamily Gryllacridinae and tribe Gryllacridini. The recorded distribution is: Indian subcontinent, Japan, Hainan, Indochina, and western Malesia (Sumatra).
Stenopelmatinae is the sole subfamily in the family Stenopelmatidae. There are about 7 genera and more than 50 described species in Stenopelmatinae.
Anancistrogera is a genus of Orthopterans, sometimes known as 'leaf-folding crickets' in the tribe Gryllacridini and typical of the newly erected genus group Anancistrogerae. The recorded distribution is: Sri Lanka, Thailand and western Malesia.
