I thought I would explain about Colin the caterpillar (<click to see yesterday’s video). He appeared on my living room carpet about a week ago (I almost stood on him!) and I can only assume he somehow hitched a ride home on some part of my clothing or my backpack. Like the Winter caterpillars I blogged about on 15 January, Colin is an Angle shades moth larva. At the moment, he’s living in a jar on my desk – I wasn’t sure how long he’d been on the carpet so wanted to feed him up before I took him back to the wild. He’s just been through a moult, from 2nd to 3rd instar I think, so he’ll need to be released soon so he can pupate in more natural surroundings.
