Introduction Keywords Aquatic Diptera Á Continental waters Á Diversity Á Distribution Á State of knowledge Family Blephariceridae (P. Zwick) For a long time, the slender, long-legged net-winged Foreword midges (wing lengths between 4 and 12 mm) were first known by the name Blepharoceridae in the With few exceptions it is difficult to extract from the 1840s. Blepharicerid larvae and pupae were only numerous Diptera families those with aquatic or discovered in 1881. They inhabit fast flowing, often ‘water dependent’ species. A key problem for most torrential waters, from sea-level to high mountains. groups is the lack of knowledge on larval ecology and Larvae attach to smooth rock substrata with their morphology of many taxa on the one hand, and the suckers, head upstream, some resisting speeds of flow great ecological plasticity on the other hand.

Most species able aquatic life cycles, i.e. Chaoboridae and occur in permanent streams, but some taxa with long Corethrellidae, that are almost exclusively found in egg diapause survive or even specialize (Dioptopsis) the pelagic zone of standing water bodies, or in the in intermittent water courses. families of Blephariceromorpha whose larvae live almost only in torrential mountain streams. Recently, a few Diptera families have been reported from Family Deuterophlebiidae aquatic habitats, e.g. Lonchopteridae (Vaillant, (G. Courtney & R. Wagner) 2002), Scatopsidae (Haenni, Vaillant pers. comm.), and Bibionidae (own observation). Another example Deuterophlebiidae (mountain midges) is one of the is the family Dolichopodidae; several thousand most specialized dipterous insects. The larvae and species have been described until now. Some species pupae of these small flies (\4 mm) are aquatic, found exhibit aquatic development of larvae; however, mostly in cold torrential streams, but ranging from larval ecology of most species remains totally small high-gradient creeks to large low-gradient unknown.
