Although most flies live and fly close to the ground, a few are known to fly at heights and a few like Oscinella (Chloropidae) are known to be dispersed by winds at altitudes of up to 2000 ft and over long distances.
Aínda que a maioría dos dípteros viven e voan preto do chan, uns poucos voan a maiores altitudes e uns poucos como Oscinella (Chloropidae) son dispersados polos ventos a altitudes de ata 610 m e a longas distancias.
