About Fannia canicularis (Linnaeus, 1761)
Morphology of Fannia canicularis: This is a slender fly that grows to a length of 4 to 6 mm. In males, the white-bordered eyes meet at the top of the head, which is called the holoptic condition. In females, the eyes do not meet. The brown-grey thorax of males has three black longitudinal stripes, while these stripes are much less distinct in females. The first two segments of the abdomen are translucently yellow, with a dark-brown base colour. Dark trapezoid markings are present on males, and these markings are barely recognizable in females. The halteres are yellowish.
