I need help to identify an insect
I have a small green flying insect attacking my flowers again this year. It is about 1/4th inch in length. A light green color with a brown head. It has antennas all most as long as it is. Six legged and an appetite for my cosmos! I have looked everything trying to find it. Last year someone told me it was a corn worm larvea. That didn't make any sense to me. I looked it up, and nope that's not it. This is an adult insect. Looks more like a beetle. It opens it's armor covering it's wings to fly. Fast too! If anyone has any idea what it is please let me know. I can't figure out how to manage it, if I can't idenify it.
