Sugarcane beetle is a sporadic but serious pest of several crops in Virginia. Although an occasional pest, outbreaks can lead to substantial losses in crops and property damage. It can cause significant damage to corn, sugarcane, rice, sweetpotato, and turfgrass, and has also been reported on strawberry, cotton, rose, and wild grasses. Populations in southern states may flare to levels that become a nuisance as it gathers at light sources. Its life cycle spans one generation per year, with adults becoming active in late spring. These beetles primarily feed on plant roots and management involves cultural practices and chemical control, focusing on targeting adult beetles to reduce crop damage. Further research is needed to develop effective pest management strategies that rely less on chemical control tactics.

This publication reviews the biology of cantharid beetles. Cantharids, known as soldier beetles or leatherwings, are commonly-encountered beetles throughout Virginia. Two species in the genus Chauliognathus are the most frequently observed; the margined leatherwing (Chauliognathus marginatus) is found during the spring and early summer, while the Pennsylvania leatherwing or goldenrod soldier beetle (Chauliognathus pensylvanicus) is active during the late summer and early fall. Both species visit a variety of wild and cultivated flowers, and they can be considered beneficial insects.
