‘dog-day’ cicada

6078   Is this some kind of clear wing Sphinx moth? It’s about 4cm long. I was mowing grass in Georgetown Ontario yesterday and this insect was very angry at my lawn mower. It kept attacking it for over 5 minutes then it came at me. I shut down the lawn mower and it left. When I started it up, it came back and when it pitched on the mower I swatted it. The green in the picture is grass blades I think. Steve.

This is a cicada (Hemiptera/Auchenorrhyncha: Cicadidae); likely one of the so-called ‘dog-day’ cicadas in the genus Neotibicen – see https://tinyurl.com/ybltmat5 for details. These insects are harmless; regardless as to how you interpreted its actions, I can assure you that it was not its intent to ‘attack’ anything.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
