Gryllus Gryllus bimaculatus

Behaviour: 

Both Field-cricket species have a very loud calling song. Gryllus bimaculatus starts singing after dusk, whereas G. campestris also sings during the day. The song consists of a series of melodious 'kre'-sounds (echemes), repeated very regularly at a rate of about 1-4/s. All echemes in a series are equsl, consisting of about 4-5 syllables. In the vicinity of a female, males produce a courtship song: a continuous rustling mixed with loud, high-pitched ticks. The calling songs of both species are quite similar and it is not alwayds easy to tell them apart. [1]
