Western Cedar Borer (Trachykele blondeli) on Jul 27, 2025

Submitter has sample

Description of specimen

I put it in a jar. Don't know how long till it degrades.

Commentary

Thank you for your report! This is not EAB. This is a native jewel beetle, Western cedar borer (Trachykele blondelii). They are not tree killers. Their grubs feed in dead conifers. Thanks for being on the lookout!
