Ochlerotatus rusticus


This is the largest dark legged member of this group with a wing length of about 7 mm. The top surface of the thorax has four broad stripes of dark scales with golden brown stripes in between.  In females the pale abdominal bands tend to broaden in the middle to form a median stripe, which may be complete, or variously discontinuous. The wing has two cross veins. Female palps are about a quarter of the length of the proboscis. The males have a hairy hypopygium with the last segment of the palp thicker than the preceding one.
