Where can I buy caterpillars?

If you can't find a caterpillar or need to provide caterpillars for an entire class, there are several places where they may be purchased together with an artificial food source. Monarch caterpillars and rearing instructions may be purchased from Monarch Watch. If you are seeking another species of butterfly, post your request to the Breeders' Circle at The Butterfly WebSite.
