The Emma field cricket is a large, stout cricket with a uniformly blackish brown back, a paler brown underside and a reddish tinge along the sides and forewings, with a dark pattern around the eyes set off by a pale band above like a frowning brow.
It is an omnivore that shelters by day in grass and leaf litter at forest edges and farmland, becoming most active at night in warm weather and calling more by day as autumn cools, with males chirping loudly to attract females.
