what I know...
1. there was about 50-75 of them about this size and what looked to be several other smaller ones as well. ( anything in these numbers can't be good right?)
2. they fly
3. bugs it kinda looks like ,but I don't think it is: ground beetle (looks thinner in shape to me, and not sure if ground beetles fly), assassin bug ( it doesn't have a huge antenna and the body is a bit different)
again I can only assume its a pest.
I live in the northern part of illinois close to WI
I currently have hoop houses up in my raised bed gardens.
I have opened the hoop houses when weather has permitted.
