Mosquito
(
Culicidae
: Coquillettidia
)
Diagnostic features
Like other culicids Coquillettidia mosquito larvae have a wide thorax (the widest part of the body) and a breathing siphon at the end of the abdomen, however in Coquillettidia the siphon is short and pointed (used for extracting oxygen from plant stems).
Typical habitats
Coquillettidia larvae can be found attached to plants around the shallow margins of still or slow flowing waters.
Feeding
They are likely to use their brush-like mouthparts to collect floating organic matter or to scrape organic slimes from plant surfaces.
Indicator value
We have little data about the water quality requirements of Coquillettidia. This genus has not been assigned tolerance values, but the family (Culicidae) have values of 3 (hard bottom sites) and 1.2 (soft bottom sites).
