The stable fly, S. calcitrans, is often found in swine farms.Its significance in food animal production can be divided into direct and indirect influences. Urban J E, Broce A, 1998. Sensory morphology and chemical ecology of the stable fly, Stomoxys calcitrans: host-seeking and ovipositional selection. Scanning electron microscopy was used to examine the external morphology of first-, second-, and third-instar stable flies (Stomoxys calcitrans (L.)). Female stable flies, Stomoxys calcitrans… In the cephalic region, the antennae, labial lobe, and maxillary palpi are morphologically similar among instars. Horn flies differ from another major cattle pest, the stable fly (Stomoxys calcitrans (Linnaeus)), in several ways. On the distribution of Stomoxys calcitrans (Diptera, Muscidae) in stalls. Flies and their bacterial loads in greyhound dog kennels in Kansas. Life cycle • Breed in decaying straw, rotting vegetable matter and especially a mixture of straw and manure.

Stomoxys calcitrans - stable fly Morphology: • Resembles house fly but has sucking mouth parts visible as a narrow pointed, shiny black proboscis protruding bayonet-like in front of head. in North America, is palearactic in origin and was probably introduced into the Americas and Australia during the colonial era (Hennig 1964, Moon 2002). Introduction Stable flies, Stomoxys calcitrans L., are obligate, blood-feeding insects. The present study was carried out to identify the morphological characters of Stomoxys calcitrans (stable fly) which play a very important role in transmission of diseases in livestock animals. • Usually 25 to 50 eggs deposited.
