Luna Moth Caterpillars
I was fortunate enough to acquire some luna moth eggs from a very kind Butterfly Forum member in the northeast to help me to re-establish lunas in this area. I'm feeding them sweetgum and black gum leaves - these are both known to be host plants for lunas, and there is plenty of it on my property, including new growth, not just old growth that's been on the trees since February or March and is old and not looking good. I put the leaves through holes I punched in the tops of leftovers containers that I had filled with water, and put the two containers in the middle of my real big cage. I haven't counted them yet, but I should be able to do so soon. They're getting big enough that they won't be able to slip through the mesh covering on the cage, so I think I can start using water picks to hold their leaves pretty soon - I attach the water picks to the sides of the cage. That'll be good in another way - they'll be farther apart and not likely to bother each other.
I got this picture of a cat that had just molted. I don't know what instar this is - first? second? Anyway, they're doing very well, eating, pooping, and growing nicely!
