Did I mention the egg

Did I mention the egg? I found it a few days ago attached to a strand of fennel and brought it in to see if it would hatch (yet another jar). It was tiny — about 0.5mm diameter — and yellow. Yesterday morning it had turned a dark bluish-black colour. This morning it had disappeared, and there was a tiny, tiny caterpillar in the jar. It's about 2mm long. I've given it some more fennel and it's munching through it. The other caterpillars are growing. I had to separate the two big ones (Boris and Ken) as they had a fight!

Also have what's either a painted lady or a red admiral chrysalis sojourning in a mixing-bowl in the kitchen — if it's the red admiral it may well overwinter in this state, whereas if it's the painted lady the butterfly should emerge in the next day or so. Either way, I need my mixing-bowl back.
