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. [2]
The horsehair worm Paragordius varius is an internal parasite and can control the behaviour of its cricket host and cause it to enter water, where the parasite continues its lifecycle and the cricket likely drowns. [29] The larvae of the sarcophagid fly Sarcophaga kellyi develop inside the body cavity of field crickets. [30]
Gryllodinus kerkennensis, the silver-bell cricket, is a cricket species which presents a disjunct distribution in the Southern part of the Western Palearctic, from North Africa and the Iberian Peninsula up to Central Asia [1] inhabiting arid, semidesert or desert land mostly associated with saline soils near water sources of lagoons or river beds depressions.
Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, thin tibiae, and long, slender antennae. The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs.
The brown cricket is considered to be a pest, especially on fields and sports grounds and around young seedlings. [2] At high densities, they can form large expanses of dead lawn. They are particularly considered to be a problematic species around cricket pitches, where they destroy the carefully maintained lawn. [ 3 ]
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).
Gryllacrididae are a family of non-jumping insects in the suborder Ensifera occurring worldwide, known commonly as leaf-rolling crickets or raspy crickets.The family historically has been broadly defined to include what are presently several other families, such as Stenopelmatidae ("Jerusalem crickets") and Rhaphidophoridae ("camel crickets"), [1] now considered separate.
Hadenoecus is a genus of common cave cricket of the southeastern United States [1] and typical of the tribe Hadenoecini.. An interesting characteristic of these crickets is their long antennae and powerful rear legs which allow for quick movement in the dark cave system.
