almost 300 spp. in 36 genera in our area(3), 50 in Canada(4); >3,600 spp. in >330 genera of 12 subfamilies worldwide(2)

worldwide; in our area more diverse in the south, esp. in sw. US(3)
Predaceous on other insects, larvae mostly on wood- and cone-borers; some adults feed on pollen; a few species are scavengers(3)
