If you start with a fresh butterfly egg you can expect to wait about 3-7 days for it to hatch. The butterfly larva (caterpillar) will eat and grow for about 2-4 weeks. It will then turn into a chrysalis and the butterfly will emerge from the chrysalis in about 1-2 weeks.
Most butterfly eggs hatch within 3-6 days, depending on the temperature in the room where the eggs are located. Use caution: do not place the cup where direct sunlight or heat will touch it. Direct sun causes the cup to become an oven. Keep the cup away from windows.
Canned fruit nectar offers everything the newborn butterfly needs to develop further. Use the canned nectar in place of sugar water and either place it in a plastic bottle cap or saturate a tissue with it. Or provide nectar-bearing flowers, especially milkweed — the monarch’s food of choice.
The eggs need to be kept warm and must have the appropriate moisture or they will either rot or dry out. Normally, the eggs are attached to the underside of a leaf so they are kept safe from predators.
Once your butterflies have emerged from the chrysalis stage, feed them with fruit, nectar (sugar water), or nectar bearing flowers.
Q: When should I release my butterflies? A: Release your butterflies as soon as possible after hatching. They can live for up to two weeks in your cage, but we recommend that you release them on the first nice day that comes along.
Butterfly chrysalises need humidity. To prevent dehydration, dunk or spray your chrysalis under/with water a couple of times a day! Chrysalises breathe through holes in their sides, called spiracles. A good wetting will not harm them.
A quick and easy method to euthanize butterfly eggs, caterpillars, chrysalises, and adults is simply to place them in the freezer overnight. Within a couple of minutes, they are normally already dead. They can be placed in a paper or plastic bag, sealed shut, and laid in the freezer.
he normal lifespan of a butterfly is 2 to 4 weeks. You will want to observe your butterflies for a few days before you release them from the habitat. Butterflies will not eat the first day but after that you need to feed them (see instructions below.)
The Butterfly Egg
The egg stage usually lasts 3-7 days but this can vary quite a bit among different species of butterflies. In fact some species overwinter as eggs and undergo diapause to survive the many months of winter.
The newly hatched butterfly is called as Caterpillar ….
Although it is important to keep butterfly eggs from dehydrating, it is also important to prevent them from sitting in an airtight container. They need air. A closed container without air flow is a perfect spot for mold and bacteria to grow.
