WEBVTT 00:00:05.994 --> 00:00:08.994 [Upbeat jingle plays] 00:00:19.439 --> 00:00:22.863 First, the butterfly starts as a very small egg 00:00:22.863 --> 00:00:25.306 laid on the leaf of a milkweed plant. 00:00:26.817 --> 00:00:31.716 About 4 days later a caterpillar is hatched and goes straight to work 00:00:31.716 --> 00:00:34.469 eating milkweed in order to grow. 00:00:37.546 --> 00:00:40.199 For 2 weeks the caterpillar eats and eats 00:00:40.199 --> 00:00:46.439 then it shimmies, shakes and sheds its skin twice as it continues to grow. 00:00:51.657 --> 00:00:56.124 Once fully grown the caterpillar attaches itself to a twig or leaf 00:00:56.124 --> 00:00:59.487 then it begins the process of metamorphosis. 00:00:59.487 --> 00:01:01.936 Unlike a silkworm that spins a cocoon 00:01:01.936 --> 00:01:06.027 the Monarch caterpillar sheds its skin one final time 00:01:06.027 --> 00:01:09.436 revealing a hard shell known as the chrysalis. 00:01:09.436 --> 00:01:11.978 Although it may look as though nothing is happening, 00:01:11.978 --> 00:01:14.663 during this 10-day chrysalis phase 00:01:14.663 --> 00:01:18.818 major changes are taking place that result in a fully grown butterfly. 00:01:18.818 --> 00:01:22.138 Once the butterfly emerges from its chrysalis, 00:01:22.138 --> 00:01:24.695 it only lives for a few months. 00:01:24.695 --> 00:01:30.197 This gives it just enough time to fly, mate and produce another egg. 00:01:30.197 --> 00:01:34.311 The entire cycle from egg to adult takes about 30 days. 00:01:34.311 --> 00:01:38.247 And that's the life cycle of the Monarch caterpillar.
