Has my caterpillar's head fallen off?Updated 9 months ago

You might see little black balls at the bottom of the cup - they're actually little balls of cast-off caterpillar exoskeleton and this is normal!

Your caterpillars will moult five times before becoming chrysalides, you may even see the remains of the moulted exoskeleton hanging from the tip of the chrysalis, but do not worry as this will not impede your butterfly from emerging.
