Superfamily Hesperioidea:HesperiidaeSuperfamily Papilionoidea:PapilionidaePieridaeNymphalidaeLycaenidaeRiodinidae A butterfly is a flying insect of the order Lepidoptera belonging to one of the superfamilies Hesperioidea (the skippers) and Papilionoidea (all other butterflies). Some authors would include also members of the superfamily Hedyloidea, the American butterfly moths. Many butterflies have striking colours and patterns on their wings. When touched by humans they tend to lose small numbers of scales, that look like a fine powder. If they lose too many scales the butterfly's ability to fly will be impaired. People who study or collect butterflies (or the closely related moths) are called lepidopterists. Butterfly watching is growing in popularity as a hobby. See more at Wikipedia.org...

>This article is about the insect. For other meanings, see Fly (disambiguation) As defined by entomologists, a fly (plural flies) is any species of insect of the order Diptera, some of which can land on food and transmit bacteria to humans. A few, like Ormia ochracea, have very advanced hearing organs. Flies are common amongst humans and have caused many diseases to spread in the past. The house-fly (Musca domestica) and mosquito are particularly common amongst humans. Other flies, such as the horse-fly (Family Tabanidae), can inflict painful bites. The larva of a fly is commonly called a maggot. See more at Wikipedia.org...
