Cimbicidae can be distinguished from other Tenthredinoidea families by the number of antennal segments, the distinctive clavate antennal form, and the wide, robust body shape (Goulet 1992).
Cimbicidae in North America are external leaf feeders. Larvae are relatively large and remarkably caterpillar-like, and are usually found curled on the underside of leaves. This family includes a couple of economic pests (see Cimbex and Abia) that can cause defoliation (Smith and Middlekauff 1987).
World: The range of the family includes Europe, Asia, North and South America (Goulet 1992).
North America: Cimbicidae are common in boreal and temperate regions in the United States and Canada (Goulet 1992).
