Nymphs are also shiny black with a golden pubescence, with the distinctively large head.
The large head and short wings readily distinguish G. campestris Linnaeus from the closely related southern field cricket, Gryllus bimaculatus De Geer.
G. bimaculatus is occasionally introduced to the UK or released from culture here (it is reared as a food source). However, it has a southern European/North African/Asian distribution and is unlikely to become established outdoors in the UK (Marshall and Haes 1988).
