Monarch butterfly eggs are somewhat difficult to find in the wild. Since it only takes 3-5 days for eggs to hatch, timing is crucial. The best sign is to watch for adult Monarchs stopping at milkweed plants. A female will usually lay only one egg per milkweed plant to ensure enough food for each larva.onarch butterfly eggs are somewhat difficult to find in the wild.

Metamorphosis is the series of developmental stages insects go through to become adults. Butterflies and moths have four stages of life: egg, larva (the caterpillar stage), pupa (the chrysalis phase in a butterfly's development), and adult.It takes a monarch butterfly just 28 to 38 days to complete its life cycle, with warmer temperatures generally being responsible for faster development. Monarch caterpillar can eat enough Milkweed in one day to equal its own body weight. Just 9 to 14 days after hatching from its eggs, a caterpillar will be about 2 long and fully grown. A caterpillar has eight pair of legs (three pair of true legs on its thorax and five pair of prolegs on its abdomen).
