The presence of knickzones allows filter-feeding groups, such as Hydropsychidae (caddisflies) or
Simuliidae (black flies), to persist despite their absence in other lentic compartments that are under direct reservoir influence.
An annotated list of and keys to the immature black flies of Alberta (Diptera:
Simuliidae).
As an example, diet of Pinguicula vulgaris, which inhabits northern sweden, consists solely of black flies (Diptera:
Simuliidae; Adler and Malmqvist, 2004).
Mediante el analisis de conglomerados (Figura 6), se puede observar claramente el agrupamiento de cuatro conjuntos, el primer grupo caracterizado por aquellos taxa abundantes espacio-temporalmente, resaltando la familia Baetidae, seguido por Leptophlebiidae, Gripopterygidae,
Simuliidae, Chironomidae y Oligochaeta.

Hydrodynamics and behavior of
Simuliidae larvae (Diptera).
La abundancia en las estaciones con impacto agricola estuvo dominada por individuos de las familias
Simuliidae (Simulium) y Chironomidae (Cricotopus, Chironominae sp.1), mientras que en las estaciones con impacto minero hubo mayor riqueza de morfoespecies (Fig.
1977; Clements 1999), and
simuliidae (moorhouse & Colbo 1973; Hunter 1979).
Fly larvae, especially Chironomidae and
Simuliidae, were important components of the diet in nearly all streams (especially in 2007), whereas amphipods were more variable in their importance.
The five most common drifting taxa (excluding terrestrial insects) were Baetis (Ephemeroptera: Baetidae), Simulium (Diptera:
Simuliidae), Trombidiformes, Orthocladiinae (Diptera: Chironomidae), and Hydropsyche (Trichoptera: Hydropsychidae); composing 45, 13, 13, 9, and 3% of the total, respectively.
Insectos de las familias Noctuidae (Lepidoptera), Corydalidae (Megaloptera), Sclerosomatidae (Opiliones) y
Simuliidae (Diptera) fueron los grupos consumidos en mayor cantidad a lo larg o del ano por adultos y juveniles.
