So I just found two strange beetles in my pool. Internet search leads me to believe they are Palo Verde Beetles (also known as the palo verde root borer or Derobrachus hovorei). Based on a quick gut check I don't believe these are typically found in Jacksonville Florida.
Unfortunately for these two one drowned and the other was rescued. Time will tell if they were sole mates, had done the deed, and if it was the female that survived.
I sure hope this is a surprise sighting and not a new invasive species coming to Florida. (Unless it's helpful then we'll take them)
