ZZYZX, CALIFORNIA–While exploring the Amboy Crater lava fields on Wednesday, we noticed these small and very active “yellow” beetles. With a little research we discovered they are Desert Spider Beetles (Cysteodemus armatus) that feed on the nectar from a variety of flowers. As you might have guessed by now, the yellow color on the heads and abdomens of the beetles is actually from the pollen of a particular yellow flower blooming in abundance the day of our visit. These beetles turn out to be important pollinators for several flower species.
