Sinopsis
Excerpt from Three Insect Enemies of Shade Trees
Life history and habits - The elm leaf-beetle passes the winter in the adult, or beetle, condition in cracks in fences or telegraph poles, under the loose bark of trees, inside window blinds in unoccupied houses, in barns, and, in fact, wherever it can secure shelter. As soon as the buds of the trees begin to swell in the spring, the beetles issue from their winter quarters and mate, and as soon as the buds burst they begin to feed upon the leaflets.

Excerpt from Three Insect Enemies of Shade Trees
The larva is elongate, reaching when full grown (fig. 3, e) half an inch in length. When first hatched it is nearly black; as it increases in size it becomes, with each shedding of the skin, more distinctly marked with yellow, and when mature the yellow predominates, occurring as a broad dorsal stripe and two lateral stripes.
The difference between the early work of the beetles and the later work of the larvae is recognized at a glance. The beetles eat entirely through the leaves and make complete, irregular holes, while the larvae simply eat the parenchyma from below, skeletonizing the leaf.
The time occupied in egg laying is long, and it thus happens that at the time when full-grown larvae, and even pupae, are to be found there are also upon the leaves freshly laid eggs.
In Washington there are invariably two generations annually, the beetles developed from the eggs laid by the overwintered beetles them selves laying their eggs in July. The adults issuing from these eggs make their appearance in August. Farther north, at New Brunswick, N. J and in the Connecticut cities, it may be said that there is nor mally a complete first generation and an incomplete second generation.
