Most crickets lay their eggs in the soil or inside the stems of plants, and to do this, female crickets have a long, needle-like or sabre-like egg-laying organ called an ovipositor. Some ground-dwelling species have dispensed with this, either depositing their eggs in an underground chamber or pushing them into the wall of a burrow. [1]
Diagram A shows the male cricket with its wings raised for the purpose of chirping. Diagram B shows the female cricket, identified via the long protruding ovipositor at the end of the abdomen. D and E show the female using the ovipositor to deposit the fertilized eggs into the ground.
This means that female crickets will mate with more than one male. Male crickets do not exhibit polygyny. The more sperm that is deposited results in greater fertilization success because more eggs are able to hatch. [7] The order in which various males mate with one female before fertilization also affects fertilization success. [8]
Gryllotalpa major,also known as the prairie mole cricket, is endemic to the United States and is the largest cricket in North America. Its natural habitat is temperate grassland and it belongs to the family Gryllotalpidae. It is threatened by habitat loss, and is currently only found in Oklahoma, Kansas, Missouri, Nebraska and Arkansas.
Ormia ochracea is a small yellow nocturnal fly in the family Tachinidae. [2] It is notable for its parasitism of crickets and its exceptionally acute directional hearing. The female is attracted to the song of the male cricket and deposits larvae on or around him, as was discovered in 1975 by the zoologist William H. Cade.
This species of cricket is popular for use as a food source for insectivorous animals like spiders, reptiles, rodents, bats and birds. [9] In addition, the tachinid fly Ormia ochracea is known to parasitize G. integer. [13] O. ochracea uses the mating call of G. integer to locate the host, then the female fly deposits larvae on the host. [14]
The notoriously loud insects rub parts of their body together to create the well-known “chirp, chirp, chirp.” However, in a cave deep in the Amazon rainforest, one species of cricket hops ...
Gryllus veletis, commonly known as the spring field cricket, is abundant throughout eastern North America. G. veletis is a solitary, aggressive, omnivorous, burrow-inhabiting species of cricket . This species is commonly confused with Gryllus pennsylvanicus (fall field cricket), as they inhabit the same geographical area.
