At one time, many field crickets found in the eastern states of the United States were assumed to be a single species and were referred to as Gryllus assimilis.However, in 1932, the entomologist B. B. Fulton showed that four populations of field cricket in North Carolina, that were morphologically identical and which were all considered to be G. assimilis, produced four different songs.
Paragordius tricuspidatus is a species of parasitic worm that affects the cricket Nemobius sylvestris.In its larval stage, the worm is microscopic, but grows into a large worm (10–15 cm or 3.9–5.9 in) inside its host after accidental ingestion since their eggs are laid at the edge of the water by rivers where crickets frequently reside.

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 ]
Spinochordodes tellinii is a parasitic nematomorph hairworm whose larvae develop in grasshoppers and crickets.This parasite is able to influence its host's behavior: once the parasite is grown, it causes its grasshopper host to jump into water, where the grasshopper will likely drown.
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.
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).
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.
Cricket paralysis virus (CrPV) is a paralytic disease affecting crickets. It was initially discovered in Australian field crickets ( Teleogryllus commodus and Teleogryllus oceanicus ) by Carl Reinganum and his colleagues at the Victorian Plant Research Institute ( Burnley , Melbourne , Australia ).
