Biology

Poorly known. Brown (1958a) observes that H. brounii resembles in general habitus, though not in its large convex eyes, the species of Stenamma found in the woodlands of the Northern Hemisphere. He speculates on the possibility of brounii feeding “like its northern analogues .... on small arthropods in the soil cover.” Colonies in the leaf litter are small and seldom seen. Specimens turn up frequently in litter and moss samples, and occasionally in pitfall traps.

Pest Status

Impacts not known, but considered unlikely to be a pest.
