I was shocked to find a wooly bear caterpillar (Great Leopard Moth) in my tent eating a Monarch pupa. I've never seen any thing like this before. But, I've never seen so much rain at one time in this area either. Lee dumped, dumped rain--13 inches at the last count. Luckily, my pots of milkweed were tall enough so the caterpillars didn't drown.
I am so glad you have had more successes than failures. But, most of the time it isn't our fault. It just happens, we do the best we can to help them.
