what’s this bug?
found flailing in our swimming pool in 90+ degree F. two nights in a row in Palm Springs, CA. Maybe it’s totally common, but I can’t seem to find what it is!! (about 2.5-3 inches long, very dark black)

Hi David,
This is a Palo Verde Root Borer, Derobrachus hovorei. The increased use of Palo Verde trees in landscaping is probably contributing an increase in sightings of the Palo Verde Root Borer in developed areas.
