The Lime Hawk-moth eggs hatched yesterday (27th) much to my surprise. The eggs were laid on the 15th of June, I had read that it can take from 3-4 days to 2 weeks for them to hatch! They are now happily munching on a Silver Birch leaf. I have to change the leaf every other day and add additional leaves as they grow, which I hope they do! The leaf has to be dry, no rain drops or dew on the leaf and not cold, the plastic container has to be sealed (no air holes), the caterpillars being so tiny can survive on the air that is trapped in the container when the lid is closed. I will update periodically, if they survive.
