It is one of eight congeneric species in a genus established for species previously placed in Delphacodes. The species is associated with native grassland habitats in the midwestern United States.
Gryllus vernalis
Northern Wood Cricket
Gryllus vernalis, the northern wood cricket, is a species of field cricket endemic to deciduous woodlands of the midwestern United States. It is distinguished by its predominantly black exoskeleton, occasionally marked with red patches on the femora, and a notably wide pronotum. The species inhabits leaf litter and shows evidence of reproductive isolation mechanisms, particularly strong female discrimination against heterospecific mates in sympatric populations.
