Last year the kids managed to successfully raise an orange tip https://forum.gardenersworld.com/discussion/1011496/orange-tip-butterfly#latest butterfly from a caterpillar, which was really exciting. Last summer we tried again with an unidentified caterpillar, which we had pinned down to a fairly vague groups of white moths. It has been pupating in the shed since then until they brought it in a couple of weeks ago. Them this morning we got this absolute beauty! Looks like a cinnabar, but most definitely wasn’t a cinnabar caterpillar, so I think it must be one of the burnets?
