Adults of Listrus spp. and other members of its subfamily Dasytinae are often extremely abundant, and may form large feeding aggregations. The dense setae and pubescence of these beetles trap pollen, which is conveyed to other flowers, making these beetles among the important beetle pollinators of flowering plants in California.
