floodplain habitat
Floodplain mosquito species lay eggs in a dry floodplain area and wait for rain to flood the surrounding wetland (such as that shown here) with enough water for the eggs to hatch. A few common species increase after these rainfall events, but recent collections in the Norfolk County (Massachusetts) Mosquito Control District have been mostly made up of two in particular: Aedes vexans and Psorophora ferox.
