larvae

Apparently, there is a type of wasp that deposits its larvae inside oak trees, where they grow inside the wood, nourished on oak bark and wasp poop. You can collect these wasp incubators — called oak galls — and do stuff with them. The Etsy seller says they’re good for all kinds of “traditional” medicinal uses like tightening the vagina and uterus after childbirth. THIS IS A BAD IDEA!
