Eristalinus October 2007-6
''Eristalinus'' is a genus of hoverfly. Most species have very distinctive eye marking in the form of spots or banding, though these features may fade on some preserved specimens. Most are stout flies, and are nimble flyers, even compared to other hoverfly species. Systematics At one time the members of this genus were divided into three clades (''Eristalinus'', ''Eristalodes'' and ''Lathyrophthalmus'') based on morphological characters such as whether the eyes were spotted or striped. Recently Pérez-Bañon ''et al.'' studying the European species of ''Eristalinus'' using a combination of molecular data and male genitalia characters have determined that the genus in Europe at least, divides neatly into two clades - ''Eristalinus'' (+ ''Lathyrophthalmus'') & ''Eristalodes''. It was also discovered that the eye patterning was not taxonomically important as ''Eristalodes'' contained members with eyes either spotted or striped. The following list is an attempt to organise some of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eristalinus Aeneus
''Eristalinus aeneus'' (Scopoli, 1763), the common lagoon fly, is a fairly common species of Hoverfly, syrphid fly observed throughout the United States and Europe. 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 Nectarivore, nectar and protein-rich Palynivore, pollen. The larvae occurs along shorelines in rock pools containing large amounts of decaying seaweed. Description ''For terms see Morphology of Diptera'' The wing length is 6.5–9.25 mm. The eyes are patterned with obvious black spots. Tergites 2 and 3 are completely shiny. The thoracic dorsum has faint greyish stripes (in Southern Europe it has five strong grey stripes). In males the eyes meet on the frons. In females the eyes are bare on the lower half. The hind tibiae have a black ring after middle, and all tarsi with segments 2–4 darkened. The male genitalia are figured by Pérez-Bañón ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
