Xanthogaleruca luteola

Elm-leaf beetle

Description

Elm-leaf beetle Xanthogaleruca luteola is a leaf-chewing beetle developing on elms (Ulmus spp.). Adults and larvae feed on leaves, skeletonizing them and reducing assimilation capacity. The larvae develop in several stages and pupate on the ground. There can be up to 3 generations per year in Europe, depending on climate. The beetle can weaken elms by repeated defoliation and significantly reduce their aesthetic value. In outbreak situations, its population can reach very high level, leading to almost complete defoliation of trees. Defoliation occurring in mid-summer can have fatal consequences for elms, especially in dry years. Its distribution covers much of southern, central, and eastern Europe, and it is locally abundant where elms grow.

Symptom

Leaves are skeletonized, with remaining veins and a lace-like appearance. Severe feeding leads to brown, shriveled foliage.
