They were small and not too gross.
And here they are on 4/21 - much bigger! Maybe double their original size already!
And their little container is full of gross-ness :(
But its a learning process for the kids - they check on them every day and are learning little tidbits about how caterpillars live. The brown in the bottom of the container is their food. They spin silk to help them get around, so that's what the "white" substance is you can see in the last picture. We aren't allowed to open the lid so that everything stays un-contaminated. They should eventually crawl to the top and form their chrysallis' and then we will be able to move them to their new home :) Once they emerge, we'll watch them for a day or so, then release them into the garden and hope they stick around and like our butterfly plants!
I'll post more pics in a day or 2!
