Species: Aedes campestris

Importance:

This species can be an important pest of man and livestock in irrigated areas in the spring and early summer, especially in close proximity to where adults emerged. It is not known to be important in disease transmission.

Biology:

This species overwinters in the egg stage. Larvae prefer shallow, sunlit pools that are alkaline and rich in organic content. Adults tend to remain within the immediate vicinity of the breeding area, although gradual dispersion from these areas does occur with adults having a flight range of about 10 miles.

Identifying Characteristics:

Pointed abdomen, pale banding on apical and basal ends of hindtarsomeres, wing vein C mostly pale scaled, middle wing vein (R₄₊₅) with as many dark scales as veins above and below it.
