Females of both horse and deer flies are aggressive, persistent feeders that quickly return to bite again if they are interrupted before they take a complete blood meal. Deer flies are bloodsucking insects considered pests to humans and cattle. Stable flies are usually found in open sunny areas, although they may enter a house during bad weather. Several fleshy rings circle the body. In a USDA Bulletin 1218, Webb and Wells estimated that horse flies would consume 1 cc of blood for their meal, and they calculated that 20 to 30 flies feeding for 6 hours would take 20 teaspoons.

A number of sand fly species are present in Europe, and in recent years, their range has increased. Most species overwinter in the larval stage and pupate during the spring and early summer. 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.

Female horse flies and deer flies are active during the day. Light colored clothing and protective mesh outdoor wear may be of some value in reducing annoyance from biting flies. When a deer fly detects a human, bear, deer, or other sizeable animal, it initially flies in circles around the creature’s head to assess its value as a potential host and to locate a suitable landing spot. It is estimated that at least 45 species of horse flies and 30 species of deer flies occur in Indiana. These flies apparently are attracted to such things as movement, shiny surfaces, carbon dioxide, and warmth. The time it takes for the eggs to hatch can also vary in some species, they will hatch within a few weeks and in others they will only hatch once the weather is warm enough.

It all starts when a female butterfly lays her eggs, usually on leaves or stems of plants. Adult life span is 30 to 60 days. Life cycle: Like all other members of the fly family, these go through complete metamorphosis, starting out as eggs, which hatch into grublike larvae (maggots), which grow, then pupate, then emerge as winged adults capable of reproducing. There are no true legs. Adult horse and deer flies are relatively large to very large (approximately 0.25 to 1.25 inches long), robust flies with a pair of huge eyes known as "compound eyes." Deer fly larvae have wormlike, cylindrical bodies that taper at both ends. Life Cycle of a Fly Stage 2 : Fly Larva. Larvae of most species are found in freshwater and saltwater marshes, some in streams, some in moist forest soils, and a few in moist decomposing wood. Horse fly larvae appear to possess a toxin in their saliva that is involved in subduing their prey. An egg mass has been found as early as May 5th and as late October 13th. 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. At best, an insecticide application aimed at adults might produce a minor and temporary reduction in biting. In contrast to horse flies, female deer flies typically feed on moving hosts and usually bite on the shoulders and head. Once ready, the caterpillar leaves its egg home and enters the big outside worl… Deer fly larvae appear to be limited to aquatic habitats, including marshes, ponds, and streams.

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.
