Butterfly Treehouse update

The caterpillars are growing at an incredibly disturbing rate. They are already at least 5x the size they were when we got them. They look to be heading towards the lid, which means they should start spinning their chrysalis' soon.

The picture are still really hard to see, it will be easier once they are in their pupa stage and I can take them out of the plastic jar and put them into the mesh house.
