insect_musicians_gryllus-ruben_WH_DIGIResembling a small Fall or Spring Field Cricket, the Southeastern Field Cricket is one of only two North American field cricket species that produce a continuous trill (the other is Gryllus texensis, a look-alike western species). These crickets can have either long wings or short wings. Not well studied, this species was recently found in the eastern panhandle of West Virginia, a range extension of several hundred miles.

The Southeastern Field Cricket is very common in the southern portion of its range and is the most numerous field cricket in Florida. It favors disturbed grassy areas. The underwings are often longer than the body, giving these crickets an odd appearance. One might even mistake a male, such as the one pictured to the left, for a female because the protruding under-wings resemble a female’s ovipositor.

Song: A continuous musical trill, sometimes given smoothly, but often interrupted by short pauses that give it a stuttering quality. The dominant frequency of the song is approximately 5 kHz.
