    This Monarch Rearing Kit contains fourteen to sixteen first to third instar monarch larvae (caterpillars) and rearing instructions. The larvae arrive in small cups and must be transferred to milkweed plants or leaves to feed. Please make sure you have fresh milkweed available before your caterpillars arrive. Each caterpillar generally needs 18 inches of milkweed to pupate. Pupation will occur in about 10 days and adults will emerge 10-14 days after pupation. These butterflies can be used for classroom instruction, student projects or to start a classroom breeding population.

    Receiving & Caring for Your Caterpillars

    • You must have fresh milkweed for your caterpillars. Please make sure you have a fresh, uncontaminated source before your caterpillars are shipped.
      • We are not responsible for caterpillar mortality due to inappropriate or contaminated food sources.
    • Click here for to learn about rearing your caterpillars and how to care for them at various stages.

    If the majority of your caterpillars do not arrive alive or perish within 48 hours of their arrival, we will replace the caterpillars or credit your account. Unfortunately, some caterpillars die due to shipping and handling. We have included a few extra caterpillars to increase the likelihood you will have a successful experience.

    Monarchs require special care and we cannot guarantee that all of your caterpillars will become butterflies. In the wild, only a small percentage of the larvae survive disease, parasites, and predation to become adults. If you follow the directions included with your kit, the majority of your caterpillars should become butterflies.

    You must notify us within 72 hours of your package delivery (including weekends) if you experienced caterpillar mortality problems. Use one of the methods below and include as much information as possible.
