I found this on the driveway, and thought, perhaps, he was lost. Not wanting a bird to get it, I scooped it up with an envelope and put it in one of my trees, but he doesn't seem to interested. He's about 2.5 to 3 inches long, but I can't measure, as he whips around with his spike when I touch him. I'm allergic to a few things, so if it's a stinger, I'd rather avoid it! What I need to know is what it eats so I can put it on it's natural food source. Please help!
