Chironomid communities as water quality indicators.
chironomid head capsules and chitinous remains (carapace, exopodites, post-abdomens) of cladocerans under a 40-450x magnification binocular microscope.
Approximately 900
chironomid species are recognized from the Neotropical region (Martin Spies, personal communication).
By contrast, Stations 10-12 in the Caroni River recorded seven species constituted primarily of Oligochaetes and
chironomid larvae at Station 12 (wet season).
Based on prospective feeding guilds and the actual food web, it was identified that the most convincing case was for a bottom feeder, given that it was the benthic oligochaetes and
chironomid larvae which were the most under-utilised, and it was suggested that one of the species of Mormyrus should be considered [8].
Muted responses in subfossil diatom and
chironomid assemblages were noted during the time of sewage inputs, and similar responses have been reported in other eutrophic Arctic sites, as well as in many macrophyte-dominated shallow lakes in general.

chironomid larvae after exposure to diazinon using fractal dimension and self-organizing map," International Journal of Ecodynamics, vol.
The most important prey for all size classes of fish in both shoreline and benthic, main-channel habitats were
chironomid larvae and pupae, which is consistent with the finding of Gray and Dauble (1979).
"One thing these lakes have in common is
chironomid (midge) larvae," he says.
Topics will include deep bobber
chironomid, wind drifting, cast and strip, targeting risers and other tackle and equipment.
