Aquatic Flies


A Male Midge

One reason for the greater number of species of aquatic Diptera compared to other groups is the range of suitable habitats.  Insects with relatively long development times such as dragonflies, mayflies and stoneflies need a habitat that is relatively stable over their lifespan.  Dipteran species can be found in all of the same habitats plus some species are able to utilize temporarily aquatic habits such as tree holes and puddles that become dry periodically.  A relatively short life cycle plus life stages that are adapted to desiccation allow Diptera to exploit these numerous and diverse habitats.  Differences between among these temporary, isolated habitats encourages adaptation to local conditions and speciation.
