Readers’ Contest With a Serious Scientifi c
Purpose
Readers of the recent issue of the Illinois Natural His-tory
Survey Reports devoted 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, inter-ested
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 fi rst reader to sub-mit
a specimen of the Asian longhorned beetle from
any Illinois county where the beetle has not been de-tected
previously.
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 diffi cult to spot in the dappled shade of trees.
Specimens should be submitted either dry and carefully
wrapped, or in a small bottle fi lled 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 fi eld guide to you if you are the
fi rst person to send a beetle from your county—excluding
Cook and DuPage counties):
