Her tongue makes an appearance anytime she eats. I hypothesize that it's to do with the last portion of swallowing. Sort of like that's the last part of sending it down the throat, like the act of sticking the tongue out is part of the muscle motion to push up the back of her tongue to send the bite down. She usually dose it with the fatter bodied butterworms and up, so the waxes, horns and silks. It doesn't happen with the supers, crickets or Phoenix Worms she's eaten. She basically completely refused the ReptiWorms, so I can't speak to them. It's really very interesting how her preferences have manifested.
The fatter hornworms definitely bring out more hunter-like behaviour in her. She downs the Phoenix Worms and superworms fast like chips or popcorn. She likes to watch the butterworms and waxworms crawl and roll around then snatch them up super fast. Waxworms have a stage, at the end when their fat has gone away and they've started their next stage of change, where they get those shells. She LOVES them that way. She likes it when the bit of worm wiggles, and they roll. Silk worms are hard to interest her in. I have to wave them at her or else keep them next to her main food dish. They hang out there, and when she's nearly out of the Phoenix Worms she goes on to the silkworms. I think they kind of bore her. It's incredible how different all the beardie tastes are.
Oh!! And I forgot to mention! She eats salad on her own! Not a ton, but enough that it's a start. She still prefers hand feeding, but I give it to her in a bowl. She does go into it. Wayne turns her lights on first thing and gives her the veg. She gets no worms until noon. It was so tough the first day!! :-(
