Natural History: Much in regard to the lifestyle of B. tschernikhi is unknown or unverified. B. pallidus, which is very similar to B. tschernikhi, has been studied more rigorously. Because of their likeness, we can assume that B. tschernikhi has a lifestyle similar to that of B. pallidus in that it is a generalist predator and scavenger. It also can be assumed to be a parasite of the pupae of streamside insects in its larval stage, but the species of insects that it has a parasitic relationship with is not known.
It is usually found in rocky, streamside areas. With the ability to thrive in both wet and dry places, this species, although sparsely populated and uncommonly observed, occupies an extremely wide range of habitats.
