The larger elm leaf beetle is 3/8 to 5/8 inches long. It is orange with large metallic blue spots. The larvae are up to ¾ inch long and are also orange. (up to 20 mm in length) orange larvae are also conspicuous and easily recognized. The larger elm leaf beetle often suddenly appears in great numbers, does tremendous defoliation for a year or two and then disappears for an indefinite time (perhaps decades). Sometimes groups of larvae can be seen on the soil surface beneath a tree. The beetles overwinter as grubs in the soil. In spring they pupate, and the new adults emerge from the soil in May. There is one generation per year. The adults may survive throughout the summer.

Healthy plants are important components of urban landscapes. These plants, however, are subjected to attacks by a myriad of pests while they are being grown in a nursery or maintained in a landscape. The ultimate goal of a successful ornamental plant pest management program is to improve the quality of plants (nurseries and greenhouses) and plant care services (landscape care operations) while minimizing pesticide use and the negative impacts of pesticide use to the environment, workers, clients, and other non-target organisms. To do so, ornamental plant growers and landscape care professionals have to understand the basic operating principles of integrated pest management, or IPM. The results of IPM can be spectacularly effective when well designed and executed.
