These two might just be lucky they ended up inside the house on some dill l picked for a bouquet. A week later, they grew big enough to see & I've been looking after them ever since! One cocooned Friday night and the other likely will soon too.
Wow, l have googled a lot about caterpillars & butterflies recently. Apparently, caterpillars develop "imaginal discs" that will become different butterfly parts as they dissolve their larva bodies inside the cocoon & build new insect bodies.
