Today tiny painted lady caterpillars arrived in a small clear cup from InsectLore. P is very excited to have her own pets! The stuff in the bottom of the cup is their food, and it provides them with everything they need. All we have to do is observe them grow! The caterpillars will remain in the cup and will eat, spin silk and grow to TEN times their original size! After seven to ten days they will hang upside down and harden into chrysalides (chrysalides are also known as pupae).
