Butterflies are insects in the clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, along with two smaller groups, the skippers (superfamily Hesperiidae) and the moth-butterflies (superfamily Hedyloidea). Butterfly fossils date to the Palaeocene, about 56 million years ago.
Butterflies feed primarily on nectar from Flowers wallpaper . Some also derive nourishment from pollen, tree sap, rotting fruit, dung, decaying flesh, and dissolved minerals in wet sand or dirt. Butterflies are important as pollinators for some species of plants. In general, they do not carry as much pollen load as bees, but they are capable of moving pollen over greater distances. Flower constancy has been observed for at least one species of butterfly.
Adult Butterfly wallpaper consume only liquids, ingested through the proboscis. They sip water from damp patches for hydration and feed on nectar from flowers, from which they get sugars for energy, and sodium and other minerals vital for reproduction. Several species of butterflies need more sodium than that provided by nectar and are attracted by sodium in salt; they sometimes land on people, attracted by the salt in human sweat. Some butterflies also visit dung, rotting fruit or carcasses to get minerals and nutrients. In many species, this mud puddling behaviour is restricted to the men, and studies have suggested that the nutrients collected may be provided as a nuptial gift, along with the spermatophore, during mating.
Butterflies use their antennae to since the air for wind and since. The antennae come in various shapes and colours; the Hesperides have a pointed angle or hook to the antennae, while most other families show knobbed antennae. The antennae are richly covered with sensory organs known as sensible. A butterfly's sense of taste is coordinated bythermoreceptors on the tarsi, or feet, which work only on contact, and are used to decide whether an egg-laying insect's offspring will be able to feed on a leaf before eggs are laid on it. Many butterflies use chemical signals, pheromones; some have specialized scent scales (androconia) or other structures (cremate or "hair pencils" in the Danaids). Vision is well developed in butterflies and most species are sensitive to the ultraviolet spectrum. Many species show sexual dimorphism in the patterns of UV reflective patches. Color vision may be widespread but has been demonstrated in only a few species. Some butterflies love wallpaper have organs of hearing and some species make stridulation and clicking sounds.

Many species of butterfly maintain territories and actively chase other species or people that may stray into them. Some species will bask or perch on chosen perches. The flight styles of butterflies are often characteristic and some species have courtship flight displays. Butterflies can only fly when their temperature is above 27 °C (81 °F); when it is cool, they can place themselves to expose the underside of the wings to the sunlight to heat themselves up. If their body temperature reaches 40 °C (104 °F), they can orientated themselves with the folded wings edgewise to the sun. Basking is an activity which is more common in the cooler hours of the morning. Some species have evolved dark windlasses to help in gathering more heat and this is especially clear in alpine forms.
As in many other insects, the lift generated by butterflies is more than can be accounted for by steady state, non transitory aerodynamics. Studies using Vanessa Atalanta in a wind tunnel show that they use a lot of aerodynamic mechanisms to generate force. These include wake capture, vortices at the wing edge, rotational mechanisms and the Wei Foch 'clap and' mechanism. Butterflies can change from one mode to another rapidly.
