Western Potato Flea Beetle
Epitrix subcrinita LeConte

Adults are small, metallic greenish-black beetles about 2 mm long that hop when disturbed. Larvae are slender, white, up to 5 mm long, and have brown heads. Adults chew small “shot holes” in leaves, and larvae feed on roots or tubers. Feeding injury is just under the skin on the potato tuber. Host plants: potatoes, tomatoes, nightshade, beans, carrots, cabbage, clover, corn, radishes.
