FYI during 2011 there was a significant population of elm leaf beetle in Canon City, Fremont Co, Colorado. Many ornamental elms suffered moderate to heavy defoliation and in some areas the damage was visible from the air. William M.

Other entomologists working on ornamentals report a similar lack of the elm leaf beetle. I would be curious to hear about other parts of North America that still see this insect. I suspect a lack of host material is the culprit in Virginia.

He would like at least 25 larvae or adults, frozen & shipped overnight -- he will provide the dry ice & pay the cost of overnight shipping. The elm leaf beetle, a well established exotic in North America, overwinters as an adult. It has at least 2 generations/yr, thus population densities are higher later in the field season. We may have a good crop of this year due to mild winter & early spring. The larvae feed on the undersides of elm leaves, skeletizing them.
