I check my pool a couple times a day for green June bugs because its mating season. They seem to be able to float for a couple hours before drowning. I get about 20 a day and only had 1 dead one in the last month. Even had one crawling along a piece of rope underwater, was weird.
Found this guy mixed in with them today. Glad I could save him so he can go and make more babies for future generations to find in their pools.
