Imported Willow Leaf Beetle
This small bluish black beetle is most often found on
willow.
The insect overwinters in protected spots on the bark as
an adult. In the spring after growth begins the insects
emerge and lay eggs. The eggs produce black larvae which
feed on the leave. The larvae feed for about a month then
pupate to produce adults. There can be more than one
generation per year.
The injury can be either skeletonizing or they may be
completely eaten.
