Readers of the recent issue of the Illinois
Natural
History Survey Reportsdevoted to invasive species in Illinois (No. 354,
November /December 1998) will be familiar with the story of the detection in
1998 of the Asian longhorned beetle (Anoplophora glabripennis) in Cook and
DuPage counties. Entomologists at the Illinois Natural History Survey are, of
course, interested in determining if this very destructive beetle has become
established elsewhere in Illinois. Along this line, the Survey is offering a
free copy of the Survey's Manual 6, Field Guide to Northeastern Longhorned
Beetles by Douglas Yanega, to the first reader to submit a specimen of the
Asian longhorned beetle from any Illinois county where the beetle has not been
detected previously.

beetle.
Hint: Search for the beetle on the trunks and limbs of its host trees such as maples, boxelders, willows, poplars, elms, locusts, and mulberries, among others. These beetles are about 1 inch long and shiny black with white spots. They are difficult to spot in the dappled shade of trees.
Specimens should be submitted either dry and carefully wrapped, or in a small bottle filled with rubbing alcohol. Please include details of the locality and date of collection and send specimens to (don't forget to provide a return address so we can mail the field guide to you if you are the first person to send a beetle from your county--excluding Cook and DuPage counties):
