Some are aquatic and a few develop in relatively dry soil. The horsefly vs. deerfly has a fairly similar life cycle, know it: Eggs: both types of flies lay from 50 to 1,000 eggs approximately, you can observe them on vertical surfaces, rocks, vegetation, etc. The use of insecticides to kill larvae is not an option because the vast majority of species develop in natural habitats in which insecticides cannot be applied due to environmental concerns. Bites can be very painful and there may be an allergic reaction to the salivary secretions released by the insects as they feed.

Horse flies (Tabanus, 52 species, and other genera) range from 3/8 to just over 1 inch long and vary in coloration by species. However, small species of deer flies can complete 2-3 generations per year and very large species of horse flies require 2-3 years in which to complete larval development. The use of insecticides against adult horse and deer flies is not a realistic option because they are relatively large to very large and unaffected by the rate of insecticide that can be applied according to product label. Often known as biting Their mouthparts include two pairs of cutting "blades" that lacerate skin and cause flow of blood out of the wound, which females lap up with a sponge-like mouthpart. During this transformative phase of their life cycle, the pupa gains the ability to extract oxygen from the air rather than the water. Follow label instructions because some people can develop allergies with repeated use, look for age restrictions. Deer fly maggots have small heads and tan or white tapered bodies, but you’re unlikely to see them. Phlebotomine sand flies occur throughout the tropics and sub-tropics, as well as in temperate zones. “Female horse and deer flies are vicious, painful biters.

However, there is one type of habitat associated with human activity that can be a source of horse flies. They have a wide host range, attacking mammals of all sizes, including humans, and some species feed on birds and reptiles. The irritation and swelling from bites usually disappears in a day or so. Their blood sucking habits also raise concerns about possible transmission of disease agents. “The real saving grace is that the life cycle should be complete soon and the problem will take care of itself,” he said in late July 2011.
