These are relatively small and live in the litter of many types of habitats. Although not tolerant of urban habitats they are often found in Pinus and other plantations where soil has not been disturbed for some time and there is plenty of litter. Indeed one endangered species, H. brevicula was known only from a plantation which has now been almost totally removed and converted to cattle farming. Intensive earch efforts for it around that site were unsuccessful.
There are no known larval stages for all species of this genus and lifehistories are thus unknown. All are flightless.
