Mosquitoes in the Maritimes fall into many categories but four very braod 
ones.
1st , Spring snowmelt species. These species (by far the largest group) 
breed in areas where melting snow froms pools in woods and raises the level 
of semipermanent and permanent ponds,puddles etc. The peak of adult activity 
is early to mid June. Depending on where you lived in the maritimes this 
winter and how much snow you got, there could have been few (Halifax area) 
or billions (Southern New Brunswick)

2nd, In late July hordes of marsh species (Colliquettidia perturbans 
especially) fly but usually not far from breeding areas (i once trapped over 
10,000 in a single night)

3rd, Late summer species that are the product of heavy rainfall followed by 
a few weeks of sunshine. They breed in puddles filled by rain. (Aedes vexans 
and Aedes cinereus) These are small and eager biters, capable of piercing 
blue jeans, they like to go for the back of the knees.They usually begin in 
early August.

4th , Species that breed without break for most of the year. This includes 
container breeding species but mainly  coastal saltmarsh mosquitos, big and 
vicious. Because they migrate far inland they can affect many parts of Nova 
Scotia and all of PEI. They fly into November
