Brigitte,
Although once very common in Virginia we have not seen it for over 20 years.
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.

Dear Forest Entomologists,
One of my colleagues, Bill Moar (formerly of Auburn U), needs some elm leaf
beetles Xanthogaleruca luteola for his research on the molecular phylogeny of
Chrysomelidae. 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. Here's more on its biology & some photos:

If you happen to find some this year & have time to help Bill, please contact
