amazing colorful mystery insect
Can you please identify what insect this is? It was on a gate at my barn, and approximately three-quarters of an inch long. it was early October, approximately 67-70 degrees outside and partially cloudy when i saw it first. I noticed it was still in the same place a few hours later when the sky was fully clouded and the temperature had started dropping, so I suspect the colder temperature was causing it to be inactive. I would love to know what this was, and if it is toxic in any way.
