Hadenoecus

Hadenoecus is a genus of common cave cricket of the southeastern United States. The Mammoth Cave system in central Kentucky is populated by the species Hadenoecus subterraneous.

An interesting characteristic of these crickets is their long antennae and powerful rear legs which allow for quick movement in the dark cave system. When threatened, H. subterraneous will jump and turn up to 180 degrees before landing again and jumping in another direction. This is suspected to be an adaptation to escape predators.

Much research has been conducted on the ecosystems of which the cave cricket is a part.
