The European field cricket is a heavy bodied, shiny black cricket with a large rounded head, a pale yellow patch at the base of each forewing, and red brown undersides to the hind thighs. Its hind wings are reduced, so it rarely flies.

Each adult digs and defends its own burrow in short, sun warmed turf, basking at the entrance by day and retreating inside at any disturbance. Nymphs take up to two years to mature before adults appear the following spring.
