Hump-winged grigs are insects belonging to the genus Cyphoderris, in the family Prophalangopsidae, and superfamily Grylloidea ( crickets). In modern times they are known only in northwestern North America and central Asia, but the fossil record indicates a wider distribution in the past. [1]
There are three species in North America: [1]
- Cyphoderris buckelli - Buckell's grig
- Cyphoderris monstrosa - Great grig
- Cyphoderris strepitans - Sagebrush grig
Hump-winged grigs are known for their unique mating habits. [2] Males call at night by sitting on a tree trunk with their head down and emitting a short, high-pitched trill. [1] When a female mounts the male, the male uses two hooks on its back to hold onto the underside of the female's abdomen while transferring spermatophore. [2] During copulation, the female eats the male's hind wings and drinks the male's blood for energy, [3] causing permanent but nonfatal damage to the male. [2] Hungry females are more likely to mate, will mount males sooner, and are less selective when choosing mating partners. [2] [3] "Virgin" males, with no hind wing damage, are generally more successful at mating than non-virgin males. [2]
