When the monarch egg hatches, a tiny caterpillar emerges and immediately eats its own eggshell. After that, it begins to eat milkweed leaves. Because caterpillar skin cannot grow, its skin is shed when the caterpillar grows too large. Caterpillars eat a lot of milkweed, particularly during the later stages (instars). You must have live, healthy, and pesticide-free milkweed available for your caterpillars to feed on when they arrive.

When the caterpillar sheds its skin the fifth time, it turns into a chrysalis. In this stage, body parts are rearranged and completely developed into the adult form. At the end of pupation, the adult monarch butterfly emerges, and pumps up its wings with fluid stored in the abdomen. The butterfly’s wings dry and harden within a few hours, after which it is ready to fly away and repeat the complete life cycle.

Because of the nature of the monarch butterfly life cycle, please let us know what your butterfly needs are at least 5 – 6 weeks before your event is scheduled. We will accommodate rush orders if we can.
