While traveling through El Dorado National Forest, I came across a stump that from afar seemed to be crawling with ants. Upon a closer inspection, I saw that the stump was actually crawling with Aradids (flat bugs). Up to this point, I've only stumbled upon lone Aradids or groups of 10 or 15 under bark, but before me there were hundreds of Aradids, milling around on the surface of a pine stump.
The Aradids stayed on the stump feverishly mating until the sun started to go down, and slowly they started to fly away. Later in the evening, we noticed termite sexuals flying around. When I looked towards the direction they were coming from, I soon realized that they were coming from the same log.
I wonder if any other insects use this stump for their reproductive business.
