1-4 mm(2)
Somewhat ant-like. Head strongly deflexed, wider than long, and wider than pronotum, abruptly constricted at base in most. Eyes usually large, coarsely granulate and weakly to strongly emarginate, with setae between facets. Two basal abdominal sternites fused.
Adults found on the underside of leaves of various trees and shrubs, and. Larvae in rotting wood, bee nests, termite nests, leaf litter, under bark.(2)
Adults are collected by beating/sweeping vegetation; sifting litter; using Malaise, flight intercept, or light traps; and by pyrethin knockdown. (4)(5)
Life Cycle
Larvae poorly known. Only those of 3 genera have been described.(2) One Australasian genus (Megaxenus) is termitophilus. Larvae of Vanonus balteatus were found in the nesting substrate of a bee nest in Mexico, probably feeding on fungi on decaying nesting material.(4)
