The Asian longhorned beetle (ALB) is an exotic pest threatening these tree species:
  • genus acer - maple and boxelder
  • genus salix - willow
  • genus ulmus - elm
  • genus aesculus - horsechestnut, buckeye
Adults are large (0.75 - 1.50 inches long) with very long black and white banded antennae.  The body is glossy black with irregular white spots.  Adults can be seen from late spring to fall depending on the climate.

As of July, 2006, the quarantine areas were lifted in Illinois after no more infestations were found.
