Atractomorpha is a genus in the Pyrgomorphidae, a family of grasshoppers, found in Africa, Asia, and Australia. [1]

Biology

Not much is written about the biology of the Atractomorpha, but they are herbivores typical of the Orthoptera, so it is understandable that some species seem to be minor pests in gardens [2] and that some, such as Atractomorpha psittacina and Atractomorpha bedeli, are significant pests in rice. [3]

As with many grasshoppers in various families, the males are smaller than the females and ride on them long before copulation. They remain there during the period in which the female achieves sexual receptiveness. Similar strategies are common in vertebrates such as some amphibians, as well as various invertebrates, where the males attempt to keep rivals from mating with the female.

At least some Atractomorpha species also share a habit with various generally sedentary Orthoptera such as some Pamphagidae, of producing their excreta in the form of relatively few, large, elongated faecal pellets, one at a time. As each pellet emerges, they kick it a considerable distance away, using the tibia of one rear leg. This apparently is a strategy for avoiding the attentions of parasitoids and predators that otherwise might have been attracted to the smell of a host midden. [4] [5]

Atractomorpha are active during the day, and their usual habitat is reeds and grasses close to rivers or streams. [6]

Taxonomy

The genus name Atractomorpha is derived from the Greek language and means "spindle-shaped" or "arrow-shaped". [7] Various families of Orthoptera (including the Acrididae and Lentulidae) include genera whose species have similarly cone-shaped heads, and there are genera within the family Pyrgomorphidae (such as Phymateus and Dictyophorus ) that do not have cone-shaped heads, [8] so their superficial appearance may be misleading even for professionals not specifically active in that field.

Catantopinae Subfamily of grasshoppers

The subfamily Catantopinae is a group of insects classified under family Acrididae. Genera such as Macrotona may sometimes called "spur-throated grasshoppers", but that name is also used for grasshoppers from other subfamilies, including the genus Melanoplus from the Melanoplinae. Indeed, the delimitation of these two subfamilies needs restudy: the Podismini for example are sometimes placed here, sometimes in the Melanoplinae.

Bandwing Subfamily of grasshoppers

Bandwings, or band-winged grasshoppers, are the subfamily Oedipodinae of grasshoppers classified under the family Acrididae. They have a worldwide distribution and were originally elevated to full family status as the Oedipodidae. Many species primarily inhabit xeric weedy fields, and some are considered to be important locusts:

Acridinae Subfamily of grasshoppers

The grasshopper subfamily Acridinae, sometimes called silent slant-faced grasshoppers, belong of the large family Acrididae in the Orthoptera: Caelifera.

<i>Conocephalus</i> Genus of cricket-like animals

Conocephalus is a genus of bush-crickets, known as coneheads. It was described by Carl Peter Thunberg in 1815.

Tetrigidae Family of grasshoppers

Tetrigidae is an ancient family in the order Orthoptera, which also includes similar families such as crickets, grasshoppers, and their allies. Species within the Tetrigidae are variously called groundhoppers, pygmy grasshoppers, pygmy devils or "grouse locusts".

Gomphocerinae Subfamily of grasshoppers

Gomphocerinae, sometimes called "slant-faced grasshoppers", are a subfamily of grasshoppers found on every continent but Antarctica and Australia.

Pyrgomorphidae Family of grasshoppers

Pyrgomorphidae is a family of grasshoppers in the order Orthoptera; it is the only family in the superfamily Pyrgomorphoidea, with a pan-tropical distribution. Their name is probably derived from pyrgos meaning "tower": a reference to the form (morph) of the head in the type genus Pyrgomorpha and other genera.

Acrotylus is a genus of grasshopper in the family Oedipodinae and the type genus of the tribe Acrotylini.

Copiphorini Tribe of insects

The Copiphorini are a tribe of bush crickets or katydids in the family Tettigoniidae. Previously considered a subfamily, they are now placed in the subfamily Conocephalinae. Like some other members of Conocephalinae, they are known as coneheads, grasshopper-like insects with an extended, cone-shaped projection on their heads that juts forward in front of the base of the antennae.

Atractomorpha crenulata, commonly known as the tobacco grasshopper, is a species of grasshopper in the subfamily Pyrgomorphinae, found in Asia.

<i>Phymateus aegrotus</i> Species of grasshopper

Phymateus aegrotus, sometimes called the blue bush locust or East African bush locust, is a pest species of grasshopper in the family Pyrgomorphidae. Unlike "locusts" the adults are not known to change their morphology on crowding, but at the hopper stage, marching behaviour of small bands may occur.

The Pyrgomorphinae are a sub-family of grasshoppers in the family Pyrgomorphidae. Species are found in, especially the warmer parts of: Central and South America, southern Europe, Africa, Asia, Australia and Pacific Islands. The type genus is Pyrgomorpha and names dates from "Pyrgomorphiden" by Brunner von Wattenwyl, 1874. The first use of Pyrgomorphinae was by Krauss in 1890.
