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]
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
Gryllotalpa gryllotalpa, commonly known as the European mole cricket, is widespread in Europe and has been introduced to the eastern United States. Its scientific name is derived from the Latin 'gryllus' ( cricket ); and 'talpa' ( mole ), because of the fine dense fur which covers it and its subterranean habits, [ 2 ] and because of the mole ...
A female produces an ovum with a full set (two sets of genes) provided solely by the mother. Thus, a male is not needed to provide sperm to fertilize the egg. This form of asexual reproduction is thought in some cases to be a serious threat to biodiversity for the subsequent lack of gene variation and potentially decreased fitness of the offspring.
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera (grasshoppers, locusts, and crickets). Mole crickets are cylindrical-bodied, fossorial insects about 3–5 cm (1.2–2.0 in) long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world ...
Ovipositor of long-horned grasshopper (the two cerci are also visible). The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs.In insects, an ovipositor consists of a maximum of three pairs of appendages.
Wētā is a loanword, from the Māori-language word wētā, which refers to this whole group of large insects; some types of wētā have a specific Māori name. [2] In New Zealand English, it is spelled either "weta" or "wētā", although the form with macrons is increasingly common in formal writing, as the Māori word weta (without macrons) instead means "filth or excrement".

The house cricket is typically gray or brownish in color, growing to 16–21 millimetres (0.63–0.83 in) in length. Males and females look similar, but females will have a brown-black, needle-like ovipositor extending from the center rear, approximately the same length as the cerci, the paired appendages towards the rear-most segment of the cricket.
