I’ve not had good luck rearing sphinx moths even though I keep trying (and they are some of my favorites, both larvae and adults). Marcie has a friend Ian, who rears a lot of them and he told both of us how to do it. Well, his way, although very successful, was too complicated for me so I modified it.
The pupae do not like to dry out so I put them in slightly damp long fibered sphagnum and put the jar in my heated-to-above-freezing garage with the other insect rearing jars. All jars came indoors April 3, 2010. (it should have been earlier but…) Within 9 days 5 had emerged which is much better than in the past.
