The genus Dolichopeza is a small group of flies including about a score 

 of species, most numerous in the Oriental and Australian regions. The 

 immature stages of the European Dolichopeza albipes Strom, a species 

 that is very close to the American species D. americana Needm., have 

 been described by Beling (1879, 1886). He found larvae in and beneath 

 moss cushions covering the piles of waste copper slag in the Harz Moun- 

 tains. On June 11, 1878, larval and pupal material was taken from a 

 tussock of the Jungermanniales liverwort Alicularia scalaris Corda. The 

 pupal period was found to be six days. Females were noted depositing their 

 eggs in these hummocks, and small swarms of males were observed dancing 

 near by. It appears that the larvae feed on the upper side of the moss 

 cushion at night, withdrawing into the interior at other times. A larva was 

 found in earth, which shows that these larvae are not dependent on mosses. 



The larva is described by Beling (1886:189-191) as being about 12 

 millimeters long and 2.3 millimeters in diameter. The body is almost 

 terete. The color is a rather bright green, the dorsum being marked 

 with two zigzag dark brown stripes. The spiracular disk has but five 

 lobes; the three dorsal lobes are long and narrow, the median tooth being 

 formed by the apparent fusion of two teeth; the ventral lobes are very 

 short, are tuberculate, and have a small, dark brown, triangular mark 

 at the inner tip. There is a small dark cross-stripe at the base of each 

 lateral lobe. The spiracles are small, are circular, and are separated by 

 a distance equal to about one and one-half the diameter of one. Beneath 

 each spiracle is a rather large, irregular, blackish brown spot. The anal 

 gills are strongly protuberant. The pupa measures about 14.5 millimeters 

 in length and 2.5 millimeters in diameter. The pronotal breathing horns
