Cheilosia longula

External images For terms see Morphology of Diptera
Cheilosia longula shares bare eyes, partly pale legs, rather long wings and fused antennal pits with Cheolosia soror and Cheilosia scutellata but it is smaller (wing length 6-8·25 mm., body length 6.0 to 9.0 mm) and darker than these species. The central facial knob is confined to the middle of face (although the face is swollen to the eye-margins) and is not semicircular viewed from above as it is in C. scutellata. The front tarsi are brownish or blackish. The scutellar bristles are rather long, median pair at least as long as scutellum and the arista has rather short but obvious hairs . In the female the scutellum usually has a yellowish tip and the humeri are usually yellowish. The sternopleuron of females is usually yellow along the posterior margin. In females the frons has minute sparse punctation and is without a median groove. The larva is described and figured by Rotheray (1994).^[1] See references for determination.^{[2][3][4][5] [6]}
