anybody know if the Hummingbird Hawk Moth((Macroglossum stellatarum) can be kept and bred in captivity.(by the average hobbyist)????I know you can buy the "goliath horn worm" and "chow" to raise them on. buy what about the adults? they are nectar feeders but would need a pretty big enclosure, etc. etc.right? i wanted to get some horn worms to raise just because they get Gianormous! and would make great feeders, if only i had something large enough to eat them.thought it would make an interesting project.any thoughts?
