Facts about this animal
The field cricket (Gryllus campestris) is a very popular insect well known from the fable “The Ant and the Cricket” but hardly ever seen by modern city-dwellers. Body size ranges from 19 to 23 mm in males and from 17 to 22 mm in females. It has a black body and wings that resemble intricate wrought iron work. The wing colour is dark black/brown, with a yellow base and black raised veins. A modified area of veins on the male's wings, known as the 'harp', enables it to produce the 'song' that is used to attract a female.
Field crickets are flightless. They live on short, warm, grasslands which have between 10 and 50 % bare ground. The males dige a burrow at the base of a grass tussock with a bare platform at the entrance from which they attract females with their 'song'. The females locate singing males by crawling across the ground to them. After mating, either inside or outside the burrow, the female lays her eggs in areas of bare ground receiving a lot of sunlight. Young cricket nymphs hatch in July and August, and grow rapidly. In early autumn a hibernation burrow is dug and the nymph spends the winter here.
Field crickets feed on various seeds, other plant material, or insects (dead or alive). They will even practice cannibalism they are very hungry.
Did you know?

Why do zoos keep this animal
The field cricket is well known, but very few urbanized people have ever seen one in the wild. Zoos therefore keep crickets for educational reasons. In many places, including the United Kingdom, the species has undergone severe declines due to changing agricultural practices. Zoos therefore engage also in conservation breeding with a view of reintroducing the species to suitable sites.
