Eggs of black-veined white (Aporia crataegi) on apple leaf A butterfly from the genus Euploea, laying eggs underneath the leaf. Butterfly eggs are protected by a hard-ridged outer layer of shell, called the chorion. This is lined with a thin coating of wax which prevents the egg from drying out before the larva has had time to fully develop.
These are thought to protect the plant as the butterfly avoids laying eggs near eggs already on a host plant, to give her own eggs the best chance of survival. A later example is the mimicking of a mammalian hormone by an ant toxin which causes long-lasting hypersensitivity, Gilbertian mimicry at a molecular level.
Dryas iulia (often incorrectly spelled julia), [3] commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed (or nymphalid) butterfly. The sole representative of its genus Dryas , [ 4 ] it is native from Brazil to southern Texas and Florida , and in summer can sometimes be found as far north as ...
The butterflies avoid laying eggs near existing ones, reducing intraspecific competition between caterpillars, which are also cannibalistic, so those that lay on vacant leaves provide their offspring with a greater chance of survival. The stipules thus appear to have evolved as Gilbertian mimics of butterfly eggs, under selection pressure from ...

The caterpillar undergoes metamorphosis and emerges a butterfly. In the adult stage, within a few hours of emerging, the butterfly's wings dry and expand, allowing it to fly. During this stage, the butterfly focuses on reproduction and finding a mate. Once the female is fertilized, the cycle begins again.
In this case, the pesky bugs, which are actually called weevils, infest the whole kernels and lay eggs in the wheat grains before it's been milled into flour, Quoc Le tells Delish.
