Chen, Y.-O., Zhang, D. & Wang, Q.-K. 2013. Alimentary canal of the lesser housefly, Fannia canicularis (Linnaeus) (Diptera: Fanniidae). - Entomol. Fennica 24: 35-42. The alimentary canal of Fannia canicularis was studied intensively for the first time, highlighting the description of morphological characteristics aid providing detailed morphometric data. Two pairs of Malpighian tubules with considerably different length were found which has been rarely documented for Calyptratae flies before. Furthermore, stout cardia and sinewy crop of the samples were observed and supposed to be responsible for the energy needed to support the longtime swarming behavior of the species. Y.-O. Chen, D.
