This was on the side of our house. I have lived here all my life and haven’t seen one. Any idea what it is?

Dear Jennifer,
We often get identification requests for Oil Beetles in the genus
Meloe from your part of the country at this time of the year.  Handle with caution.  Oil Beetles are Blister Beetles and they can exude a compound known as cantharidin which is known to cause blistering in human skin.  It is also the substance found in the aphrodisiac Spanish Fly.
