What's That Bug? does not endorse extermination

Rhino Beetle in Oregon?
Location: Ashland, Oregon, USA
July 8, 2011 12:45 am
My daughter found this beetle while we were camping in Southern Oregon (Ashland). The horn made me think of rhino beetles but it’s fairly small. Are there rhino beetles indigenous to Oregon? What species of insect is this?

Rugose Stag Beetle

Dear Dr. Aaron Molen,
BugGuide does not have any reports of Rhinoceros Beetles in the subfamily Dynastinae in Oregon, however, there are reports from California.  They also include the disclaimer:  “Range and date information may be incomplete, overinclusive, or just plain wrong.”  This is actually a Rugose Stag Beetle,
Sinodendron rugosum, and we identified it on BugGuide and the horn indicates he is a male.

    I recently found one of these in Portland, OR., which has a greatly different climate than Ashland and Northern California. He did seem a bit sluggish, but was alive when I found him. Perhaps the range is as incomplete as they concede?

      In the time that has elapsed since August 2011 when we first published this posting of a Rugose Stag Beetle, there have been additional sightings on BugGuide, increasing the range of the Rugose Stag Beetle to include Oregon, Washington and British Columbia.
