Adults are brown with thin yellow bands on the abdomen and resemble paper wasps. The front wings are brown while hind wings are transparent.

The larvae feed on grape species. The eggs hatch on the soil surface and the larvae tunnels into the root system of their host plant. The damage causes reduces vine growth, smaller leaves and reduced berry size.[3]
