Lesser house fly : ウィキペディア英語版 | Lesser house fly
The lesser house fly or little house fly, ''Fannia canicularis'', is somewhat smaller () than the common housefly. It is best known for its habit of entering buildings and circling near the center of rooms. It is slender, and the median vein in the wing is straight. Larvae feed on all manner of decaying organic matter, including carrion. Among the Fanniidae, this species is the one most frequently associated with myiasis. == Morphology == ''Fannia canicularis'' is a slim fly reaching a length of from 4 to 6 mm. The white-bordered eyes meet above in the male, a condition described as holoptic. In females, the eyes do not meet. The brown-grey thorax has three black, longitudinal stripes in the males. These are much less distinct in the female. The first two segments of the abdomen are translucently yellow with a dark-brown basal colour. The dark trapezoid marks of the males are hardly recognizable in the females. The halteres are yellowish.
