Distribution. NWR: AP, Komi, LP, NP,PP, RK, SPb, VP. Adjacent countries: Norway, Sweden, Finland, Lithuania and Belarus. Europe (ranging northward to the UK, Belgium, the Netherlands and Denmark); the Holarctic.

Note. The northernmost record of Aedes sticticus is 71°30 ′ 38.91 ″ N, 52°18 ′ 3 ″ E, Novaya Zemlya (Fig. 3f; Sack, 1923). However, in Fennoscandia the species was recorded only from the southern parts of Sweden, Norway and Finland. The northernmost records of Ae. sticticus from these countries are as follows: Norway: 59°56 ′ 25.58 ″ N, 10°56 ′ 28.91 ″ E, Lerenskog (Natvig, 1948); 59°46 ′ 59.48 ″ N, 11°11 ′ 40.04 ″ E, Oieren (Mehl et al., 1983); 61°33 ′ 27.28 ″ N, 9°56 ′ 15.52 ″ E, Ser Fron (Mehl, 1996); Sweden: 60°38 ′ 46.83 ″ N, 15°51 ′ 24.71 ″ E, Karlsbyn (Natvig, 1948); 61°3 ′ 40.76 ″ N, 14°12 ′ 53.5 ″ E, Dalarna (Lundström et al., 2013); Finland: 60°24 ′ N, 19°54 ′ E, Åland (Culverwell et al., 2021). In the case of partial loss of thoracic and abdominal scales, females of Ae. sticticus cannot be distinguished from some other Aedes species, e.g. Ae. communis .
