Adult drone flies, which can exceed half an inch in length, are easily discernible from honey bees due to their lack of a narrowed waist between the thorax and abdomen, and they possess only two wings compared to the four wings of honey bees. Their thorax and first abdominal segment are adorned with short, brownish-yellow hairs. The body typically appears dark brown to black, featuring yellow-orange markings on the side of the second abdominal segment, along with a narrow yellow-orange band spanning the third abdominal segment. Differentiating between male and female drone flies is common among many fly species, with males distinguished by larger eyes that nearly touch, while females have smaller eyes spaced farther apart. A key characteristic unique to flies belonging to the Syrphidae family is the presence of a “false vein” or spurious vein in their wings. This vein differs from others as it does not terminate at the end of the wing or intersect with another vein, and it lacks the same level of hardness as other wing veins.
