Hello, I believe this is a water scorpion (actually 2) that were found in a public swimming pool today (early August) in Tucson AZ. It is about 2 inches long, abit longer if you measure the tail like appendage. Water bugs are not uncommon this time of year, but this variety was new to me. I identified it as a water scorpion from other posts on your site. How do water bugs survive in swimming pools when the chemicals that make the water safe for swimming are supposed to destroy organic matter?
You are correct. These are Water Scorpions. Water Scorpions and most other adult aquatic insects breath air, in the case of the Water Scorpion, through the breathing tube at the end of the abdomen which functions like a snorkel. Since they do not take oxygen from the water, they are not adversely affected by the chlorine in the way that fish with gills may die in chlorinated water. If conditions become unbearable, the Water Scorpions just take flight and find a better habitat.
