Gryllus pennsylvanicus

Undergrowth

Spring field cricket (Gryllus veletis) is identical in appearance and the male has the same calling song. The two species can be distinguished in the field only by the date of observation. Spring field cricket overwinters as mid-sized juveniles and matures in mid-May. The population peaks in mid-June. The chirping becomes less frequent in late July, and disappears altogether in early to mid-August. There is very little overlap between the two species.

Plant material including seeds and seedlings, small fruits, dead and dying insects.

Overwinters as eggs and matures in early to mid-August. The population peaks in mid-September. They are killed by heavy frosts in in the fall and are finished off by the first hard freeze in November.

Individuals chirp mostly at night. When the nights are cold they chirp only during the daytime.
