ALB Compared to the Whitespotted Pine Sawyer

The Asian longhorned beetle (Anoplophora glabripennis), has a native look-alike that you may encounter in New York State, the whitespotted pine sawyer (Monochamus scutellatus). Upon first glance, it can be easily mistaken for the ALB. However, the whitespotted pine sawyer has a distinctive white spot at the top of where its wing covers ("elytra") meet, while the ALB has none. This comparison of both species shows the location of that white spot on both the male and female whitespotted pine sawyers.

Also, note that the white markings on the wing covers and antennae are much more visible on the Asian longhorned beetle. If you think you have seen an ALB e-mail us a photo or mail the insect to our lab for identification.

The whitespotted pine sawyer has a white half-circle at the top center of its wing covers. The Asian longhorned beetle does not.
