Flies of North America - Order Diptera. Flies are prevalent in virtually all habitats, with over 16,000 species in North America. Flies can be distinguished from all other insects in that they only have one pair of normal wings. The other pair has evolved into small ball-like structures called halteres, thought to be used as stabilizing organs during flight. Most flies have compound eyes and mouthparts adapted for piercing, lapping or sucking fluids. Insects & Spiders | Flies Index | Syrphidae | Bee Flies | Robber Flies |
