Which of the following is correctly identified as a stable fly?

The correct identification of the stable fly is Stomoxys calcitrans. This species is known for its characteristic behavior and ecology. Stable flies are typically found in agricultural settings, often near livestock, where they feed on blood. They have a distinctive appearance, with a grayish body and patterned wings that differentiate them from house flies and other fly species.

Recognizing stable flies is important for pest management, as they can transmit diseases to livestock and are a nuisance to both animals and humans. Their bite is painful, further underscoring the need for effective control measures in areas where they are prevalent.

In contrast, the other mentioned species serve different ecological roles and do not share the same characteristics as stable flies. Musca domestica, known as the house fly, has different feeding habits and habitat preferences. Fannia canicularis, or the little house fly, has a distinct appearance and life cycle, while Musca autumnalis, known as the face fly, primarily feeds on secretions from animals' eyes and noses. Recognizing these differences is vital for effective pest control strategies.
