White-Spotted Sawyer (Monochamus scutellatus) on Jul 20, 2023

Submitter does not have a specimen

Description of specimen

The specimen was a large black beetle with irregular spots and long stripped antennae.

Commentary

Thank you for your report! That is our native white-spotted sawyer, Monochamus scutellatus. Probably our nearest look-alike to ALB, but they can be recognized by the rough-textured wing covers and the pattern of white spots.
