Culiseta melanura have a unique life cycle for a mosquito; the mosquito over winters as a larva as opposed to an adult. Eggs are laid singly onto the surface of water in crypts, which are stagnant pools of water. Eggs cannot survive without water, or they will dry out. Females can oviposit between 30 and 300 eggs at one time. The time it takes for the egg to hatch and undergo pupation is dependent upon the temperature of the environment. Adults disperse and reproduce within a 100 km radius of the site where they emerged.
Average eggs per season: 30 -300.
Key Reproductive Features: semelparous ; sexual ; fertilization (Internal ); oviparous
Females lay eggs in a place suitable for larval development, after which there is no further parental involvement.
Parental Investment: pre-fertilization (Provisioning)

There are several problems with this article: 1. Most mosquitoes overwinter as eggs. 2. The eggs of Cs. melanura are laid in rafts. (Chamberlain, R.W., W.D. Sudia and D. B. Nelson. 1955.

(I have pictures if you like.) 4. your description of what Cs. melanura looks like is pretty generic.
