I am glad that the nymph caught its own prey! With first instar nymphs, hand feeding would be very difficult and any honey can be a disaster. If I have many nymphs, the best thing for me is to wait and see.
I have tried to hand feed first instar nymphs with problems like bent or stuck legs, and it usually, but not always, ends up in heartbreak. It seems that the stress of the hand feeding, or even handling, is enough to kill them.
As I gained a little experience with hatching mantids, I have found it best not to mess with first instar nymphs at all. Usually, I don't even separate them until second instar. I always try to hatch them in very large containers so I don't have to. Some species die easily from stress, like attempting to feed too early, or being crowded.
