Horse flies (Tabanus spp.) are larger than deer flies and usually have solid or striped eyes. In both horse and deer flies, there is a space between the eyes in the females (when viewed from above), while the eyes of males nearly touch. Only the females drink blood. They are attracted to large, dark, moving objects.
Mosquito larvae are aquatic, with a large head and thorax and narrow, wormlike abdomen. They typically hang just below the water surface, breathing air through tubes at the end of the abdomen. When disturbed, they wriggle downward.
