Coordinator notes: The two species (<i>D. maculalis</i> and <i>D. funeralis</i>) cannot be distinguished in typical dorsal view photos. It would be necessary to see mouth parts at high magnification or examine genitalia to make specific determinations. It is best to consider photos of these species as representing a species group. However, one character that can be used is the extent of the white patch on the underside of the abdomen. D. funeralis individuals have a solid white patch on the underside of the abdomen on segments 1-5 (or may have a slight break on segment 3). D. maculalis individuals have a broken white patch, where about 1/2 of segments 3 and 4 are clearly dark. Basically, maculalis looks striped on the underside, whereas funeralis looks like it is basically solid white..
