Your letter to the bugman: This cute little fellow got us all wondering what species he might be. He was spotted on the bank of the Willamette river near the forest’s edge in April. Any idea? Thanks so much for any insight you might have!

Dear Beetle Bystander,
This is a Desert Spider Beetle or Inflated Beetle in the genus Cysteodemus. According to BugGuide, there are two species in North America and neither is reported from Oregon, and the range is listed as “sw. US: Colorado, Mojave, and Chihuahuan deserts.” We are not certain how unusual this Oregon sighting is.
