Genera

Jerusalem crickets (or potato bugs) [1] are a group of large, flightless insects in the genera Ammopelmatus and Stenopelmatus , together comprising the tribe Stenopelmatini. The former genus is native to the western United States and parts of Mexico, while the latter genus is from Central America. [2]

Contents

Despite their common names, these insects are neither true crickets (which belong to the family Gryllidae), nor are they native to Jerusalem. These nocturnal insects use their strong mandibles to feed primarily on dead organic matter but can also eat other insects. [3] Their highly adapted feet are used for burrowing beneath moist soil to feed on decaying root plants and tubers.

While Jerusalem crickets are not venomous, they can emit a foul smell and are capable of inflicting a painful bite.

Classification

There are 19 species recognized as valid in the genus Stenopelmatus , as presently delimited (with 13 more of uncertain status and potentially not valid), though the genus was formerly much larger, including most of the species now placed in the genus Ammopelmatus , which contains 20 additional species. [2] The family Stenopelmatidae and subfamily Stenopelmatinae contain several Old World genera, but only the genera in the tribe Stenopelmatini (all New World) are referred to as Jerusalem crickets. Other families in the same superfamily (Stenopelmatoidea) in Australia and New Zealand include the wētā and king crickets. They are similar to stenopelmatines in many respects.

Similar to true crickets, each species of Jerusalem cricket produces a different song during mating. This song takes the form of a characteristic drumming in which the insect beats its abdomen against the ground.

No species have wings with sound-producing structures; moreover, evidently none has structures it could use to hear sound. [4] [5] This contrasts with true crickets and katydids, who use their wings to produce sounds and have hearing organs to sense sounds of others. Jerusalem crickets seem unable to hiss by forcing air through their spiracles, as some beetles and cockroaches do. Instead, the few Jerusalem crickets that do make sound rub their hind legs against the sides of the abdomen, producing a rasping, hissing noise. [6] This hiss may serve to deter predators rather than to communicate with other crickets. For such purposes, Jerusalem crickets rely on substrate vibrations felt by subgenual organs located in all six of the insect's legs. [7]

Several hypotheses attempt to explain the origin of the term "Jerusalem cricket". [8] One suggests the term originated from a mixing of Navajo and Christian terminology, resulting from the strong connection Franciscan priests had with the Navajos in developing their dictionary and vocabulary. Such priests may have heard the Navajos speak of a "skull insect" and took this as a reference to Calvary (also known as Skull Hill) outside Jerusalem near the place where Jesus was crucified.

Several Navajo names refer to the insect's head: [8]

Other names include the Hopi qalatötö ("shiny bug"), [8] the Spanish niño de la tierra ("child of the earth") and cara de niño ("child's face"). [8] [9]

Orthoptera is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā.

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.

Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants.

<span class="mw-page-title-main">Stenopelmatidae</span> Family of cricket-like animals

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.

<i>Hemiandrus</i> Genus of orthopteran insects

Hemiandrus is a genus of wētā in the family Anostostomatidae. In New Zealand they are known as ground wētā due to their burrowing lifestyle. Hemiandrus wētā are nocturnal, and reside in these burrows during the day. Ground wētā seal the entrance of their burrow during the day with a soil plug or door so that their burrow is concealed. Ground wētā adults are smaller than other types of wētā, with the unusual trait of having either long or short ovipositors, depending on the species. The name of this genus comes from this trait as hemi- mean half and -andrus means male, as the species where the female has a short ovipositor can sometimes be mistaken for a male. This genus has a diverse diet, depending on the species.
