Ochlerotatus pullatus
Ochlerotatus pullatus is a boreoalpine mosquito species with a discontinuous Holarctic distribution. In eastern North America, it has been recorded from alpine and subalpine habitats, with a notable range extension documented in the Chic-Chocs mountains of eastern Québec. The species develops in temporary snowmelt pools at elevations around 1000 m, where it can be locally dominant. Its presence in disjunct mountain populations has been discussed in relation to postglacial dispersal patterns.
