This publication is available in a PDF file format only.

Adults are small, stout, shiny oval beetles measuring about 3 mm (0.125 inch) long. Their metallic color ranges from black to bluish–green. The bright yellow, spindle-shaped eggs are laid upright in clusters. Larvae are small, somewhat shiny grubs with a black head, thorax, and legs. The abdomen may appear somewhat greenish-yellow and has several parallel rows of black bumps. Larvae measure about 5–8 mm (about 0.25 inch) long when mature. The naked pupae are a mottled yellow-brown, with the wings, legs, and head clearly distinguishable, and are attached to the leaf by the tip of the abdomen.
