Please can you add the following: The caterpillars are all on the lid and were doing lots of shaking earlier. I think they are all getting ready to turn into a chrysalis!
The caterpillars are still around 4cm long and are spending quite a lot of time crawling up to the lid. They are practising hanging from the lid, ready for when they become chrysalises (cocoons). Isn’t it amazing how much they have grown since day 1!
