Some species begin incubation with the first egg, causing the young to hatch at different times; others begin after laying the second egg, so that the third chick will be smaller and more vulnerable to food shortages. Some start to incubate after the last egg of the clutch, causing the young to hatch simultaneously. [10] Incubation periods for ...
Five butterfly species in the United States have gone extinct since 1950, and dozens more are on the verge of extinction according to the Xerces Society for Invertebrate Conservation.
A fertilized animal later releases a gelatinous egg mass, and the eggs float freely until hatching. Their embryonic shells are lost within the first few days after hatching. The gymnosomes, like other shell-less opisthobranchs, [a] discard their shells at metamorphosis, with the retractor muscles being severed and the shell lost. [10]
The female incubates the eggs for 11–14 days before they hatch. Then the female feeds the offspring while the male teaches them to fly and leave the nest, usually within 18 days of birth. The male also feeds the offspring a little less than half the time, easing the burden on the female.

The large white eggs hatch approximately one week after being laid and live as a group for some time. [11] [12] [13] The hatching period constitutes around two to seven hours. Upon hatching, they cause a lot of damage to the host plant by eating away at and destroying the host plant.
After hatching, the caterpillar goes through multiple developmental stages. In its early stages, the caterpillar resembles bird droppings for camouflage and has eye spots to defend against predators. Once the larval stage is complete, the caterpillar enters the pupal stage, forming a chrysalis–a hard shell used for protection while it ...
