Caterpillars are also affected by a range of bacterial, viral and fungal diseases, and only a small percentage of the butterfly eggs laid ever reach adulthood. [79] The bacterium Bacillus thuringiensis has been used in sprays to reduce damage to crops by the caterpillars of the large white butterfly, and the entomopathogenic fungus Beauveria ...
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.

The adult butterfly emerges (ecloses) from this and expands its wings by pumping haemolymph into the wing veins. [13] Although this sudden and rapid change from pupa to imago is often called metamorphosis, metamorphosis is really the whole series of changes that an insect undergoes from egg to adult.
These caterpillars feed on stonecrop (Sedum species, mainly Sedum telephium, Sedum album, Sedum rupestre and Sedum ropsea), Hylotelephium caucasicum and houseleek (Sempervivum species). [3] [7] When the caterpillar is fully grown it will pupate on the ground, forming a loose cocoon from which the adult butterfly emerges following metamorphosis. [9]
The butterflies form the clade Rhopalocera, which is composed of three superfamilies: Hedyloidea (the moth butterfly family Hedylidae), the Hesperioidea (the skipper family Hesperiidae), and the Papilionoidea (the true butterfly families Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Riodinidae). All of these families are monophyletic.
