Common Name: Locust Leafminer
Order: Coleoptera Family: Chrysomelidae Pest Status: Locust leaf miners can cause the leaves of trees to appear unsightly. High populations can cause minor injury. Appearance: Adults are small, flattened beetles that are about 1/2-inch long. Their heads are black and the thorax and outer margins of the wing covers are orange. They have a prominent black dorsal stripe extending down their backs. The wing covers are deeply pitted and have three longitudinal ridges. Life Cycle: Adults overwinter in bark crevices or leaf litter and emerge in the spring. Eggs are deposited on the underside of leaves. Upon hatching, the larvae feed together in blister-like mines. Shortly after, they disperse and excavate their own mines in preparation for pupation. There are two generations per year. Where to Collect: Leaf miners are commonly found around fruit-bearing trees. |
