Jack and I went to Hidden Lake this morning and were amazed at these large insects digging tunnels on the dam. There were hundreds of the things and others flying just above them. I couldn’t get a decent photo so cadged this from a DuckDuckGo search but it looks like the same bug (and Eastern Velvet Ant) with more orange than red. I will try to get down there later today with a macro lens and see if I can get a shot of my own, but if there are any entomology fans out there, I’d like to know if this is the correct ID.
