Thread subject: Diptera.info :: Mosquito laying eggs - Culex cf. pipiens

Hi,
In a July night of 2015 I observed this mosquito female laying eggs in a water basin. The eggs formed a nice little raft. I would really like to know the species - is it our common Culex pipiens?
Thanks for help, Sundew

Culex for sure, and most likely pipiens

Thank you very much, Tony! I have no Culex key, and in our region 6 species are said to occur: hortensis, martinii, modestus, pipiens, territans, torrentium. Can any of them be excluded with certainty?

It's not modestus, which has a much shorter hind basitarsus. Nor martinii, which has no pale bands on the abdomen. Nor hortensis or territans which have pale apical bands on the abdominal segments. Which leaves pipiens and torrentium. To separate these species, characters of the male genitalia appear to be the most reliable features.
