Hister Beetles do not hiss or make noise. They are tiny scavengers that take advantage of their situation.
There are a large variety of Hister Beetles and most species have not been studied. These tiny beetles can be found making homes anywhere and out of anything. They are so small, when they tuck their legs under themselves, they can be mistaken for tiny black seeds. This could be a defense mechanism.
Some species live in trees, others in abandoned rodent burrows. Some species eat only fungi, while others eat anything they can find including animal dung and rotting produce. The family of Hister Beetles has been efficient at carving out a niche for its individual species, varying it based on each beetle's environment and circumstances.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
