Scientific name: Stomoxys calcitrans (Linnaeus)
Facts: Stable fly adults are about 1/4 inch long and have grayish-colored bodies and piercing-sucking mouthparts. Except for a pointed, stiff, slender beak sticking out from under the head, a stable fly adult resembles a house fly. Seven dark, rounded spots are on the upper side of the abdomen. Larvae have hooks in their mouthparts and feed in manure.
