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]
Range: Fennoscandia south to the Pyrenees Italy and Yugoslavia.Ireland eastwards through USSR to eastern Siberia [7] [8]
The habitat is deciduous and coniferous forest and conifer plantations in glades, clearings, and by tracks and taiga
Adults fly at heights up to 3m, often settling on low-growing vegetation in dappled sunlight. Flowers visited include species of Achillea , Calluna , Cirsium , Euphorbia , Galium and Potentilla erecta . Flies from the end of June to October, with a peak in September.The larva is an internal feeder on the tissues of various large, woodland basidiomycetes mainly Boletus , Leccinum and Suillus . [9]
Eupeodes luniger is a common species of hoverfly.
Cheilosia albipila is a European and Palearctic species of hoverfly. Like most Cheilosia it is black, and because of this may often be overlooked as a hoverfly. It is little recorded but probably widespread and common and maybe overlooked because adult flight periods are early in the year, before many hoverfly recorders are active.
Leucozona lucorum is a Palearctic and Nearctic species of hoverfly.
Cheilosia variabilis, common name figwort cheilosia, is a species of hoverfly belonging to the family Syrphidae.
Cheilosia grossa is a widespread European species of hoverfly. Adults can be found in spring on sallow catkins and the larvae tunnel in the stems of various thistle species.
Cheilosia albitarsis is an abundant European species of hoverfly. Adults can be found in spring visiting buttercup flowers and this plant is also the larval hostplant.
Cheilosia bergenstammi is a widespread European species of hoverfly. Adults can be found in summer visiting ragwort flowers and this plant is also the larval hostplant.
Cheilosia latifrons is a species of 'flower flies' or hoverflies belonging to the family Syrphidae subfamily Eristalinae.
Paragus haemorrhous,the Black-backed Grass Skimmer is a common widespread species of hoverfly found in many parts of Europe, Africa and the Nearctic. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers from which they get both energy-giving nectar and protein-rich pollen. The larvae are predators on aphids.
Melangyna arctica is a Holarctic species of hoverfly.
Meligramma guttatum is a Holarctic species of hoverfly.
Eumerus funeralis or lesser bulb fly is a species of Hoverfly, from the family Syrphidae, in the order Diptera. E. funeralis appears in Peck (1988) as a synonym of E. strigatus (Fallen), but was reinstated as the correct name for tuberculatus Rondani, sensu auctorum by Speight et al. (1998).
Cheilosia impressa is a Palearctic species of hoverfly. Like most members of its genus C. impressa is a rather small, dark insect and identification can be problematic.
Brachyopa insensilis is a Palearctic species of hoverflies.
Cheilosia antiqua is a European species of hoverfly.
Cheilosia scutellata is a Palearctic hoverfly.
Cheilosia vernalis is a Palearctic hoverfly.
Lejogaster tarsata is a Palearctic hoverfly
Mallota cimbiciformis is a Palearctic hoverfly.
Cheilosia fraterna is a Palearctic hoverfly.
