I found a woolly caterpillar
I found a woolly caterpillar in my house 10 days ago. It could have dropped off a house plant. It is freezing outside so I put it in a large aerated container with twigs, leaves and moisture. It seems active and healthy so far. It's color at first was a faint purple but now seems all black. Will it spin a chrysalis ? Should I keep it until the Spring ? What should I give it to eat ?
