Someone asked about how I keep my pupa over the winter. I used to have an enclosure that I could raise caterpillars in and let them pupate also. It started falling apart and I don’t have a new one yet. I don’t really raise that many anymore anyway, so I don’t have that many to overwinter.
The ones I do have I keep in canning jars, and use mosquito netting to allow air circulation but to keep predators out. They’ve usually pupated on sticks which I can then break to fit into the jar. And I keep the jar outside, usually close to the house.
Here is a picture of one jar from the top:
Here is just the lid and the netting:
The netting is the kind with only really small holes. Some parasitic wasps are very small and it has to be able to keep them out. Here’s a close up the netting, my camera doesn’t do close ups of tiny things though, so it may not be that helpful:
