Sorry I have no pic to post. I saw one of these today flying around the large oak tree in our yard, then over to the southern magnolia. No exageration, it was 2- 2 1/2 inches long at least, rusty reddish front half and wings, appearing to have double wings, and neon green abdomen with dark stripes. Like chartreuse. Not yellow or orange or light green, bright chartreuse. The body seemed wider than even very large hornets. I've seen European hornets and cicada killers and bald-faced. I have seen these green things before on purple passion flower vine blossoms. We live in inland Central Florida just about at the sub-tropical/tropical line if there is such a thing. My son claims to have been stung by one of these once and said it felt like being stabbed, though he has never been stabbed
. Any opinions?
