This family is best known for damaging plants but that is a small number in one genus of this family. There are 1,900 species with over 600 in North America. It is a large and diverse family. Some larvae develop in the roots of plants, some are scavengers, others are parasites. Knowing the hosts associated with the larval feeding patterns can be important and helpful in making an identification. The adults feed on pollen and nectar and assist with pollination. Mostly they overwinter as pupa but some adults have been found in the winter months.
