Featured Arthropod: Aedes nigripes (Diptera: Culicidae)

Aedes nigripesAedes nigripes (Zett, 1840) is probably the most abundant Arctic mosquito (Vockeroth 1954) and is found all across the Arctic. Its larvae grow rapidly in snowmelt tundra ponds during early summer and the adult females emerge to fiercely seek blood from caribou and other wildlife. Autogeny (i.e., reproducing without a blood meal) has been documented in this species (Corbett 1964, 1967) although it is unclear if this presumed adaptation to low blood-meal density is present in all populations (Culler, pers. obs.). In Greenland, the timing of pond thaw in spring strongly predicts its emergence time, and the number of immatures that survive to the adult stage depends on pond temperature and mortality from beetle predators (Culler et al. 2015). –L.
