Newbie? Help sick bsc.
I am new to this butterfly raising. I have successfully raised from eggs five bsc to their last in-stars. I ran out of parsley plants on Sunday and had to buy organic plants at the grocery store. The plants said they were organic. I put my little caterpillars on the new plants and was devastated to find them all curled up on the bottom of the container dying. They were fine 12 hours ago and getting ready to pupate shortly. They are oozing and still move when I touch them with a brush. I don't know what I did but am so upset about this that I don't know if I will want to try this again in the spring. I have previously raised my first cats to butterfly's. It was so exciting when I found these eggs on my parsley and the have been healthy up to this. Please advise ASAP with any diagnosis. Thanks carol.
