Butthead has the same behavior as Benchley. Benchley noms first then figures out I'm not food after. Unfortunately, he's an adult or nearly so. I'd love it if he was a little worm nomming on me, not so much given his size. On the other hand, I love his appetite and feeding response, he cleans up anything that is rejected, including 1 gm pinks. I've never offered him a pile of pinks to see what he'd do, but I imagine he would eat a pile of them, like 20 or more!
