Good question! I don’t have an answer, but it is a really good question. I know with some which form chrysalis they will move their tail end when touched, but bsfl don’t pupate like that. I would say just put the container aside and wait a good long time until there’s no doubt. I have had the same bsfl for so many months and they just won’t pupate but are still alive and squirming.
Same here! Once they turn black I like to put them in the pots in my chameleon enclosures. The hatch into flies randomly and my chameleons get unexpected hunting treats
Ahhhh I had this question for awhile, it’s so hard to tell. Honestly you have wait…. And wait and wait and see if they end up coming out of their chrysalis. I do know it can take weeks!!!! So good luck with your batch!
