One reader of my blog ““Zombie flies” are not in Saudi Arabia (at least, not yet)” , wrote me a private message, disagreeing that an unequivocal identification of Megaselia scalaris could be made, based on the published figure “C” in that paper. Technically, this reader is correct that one could theoretically assemble a group of other Megaselia that would be indistinguishable from M. scalaris based on this photo. The context is important, however, as M. scalaris is abundant in dead insects and frequently found in dead honey bees (I have seen this association from dead honey bees many times from various parts of the world). Thus, what I should have written is that based on the incomplete photo and the situation where the flies were found, it is almost certain that they are M. scalaris.
