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. [1] [2]

Size

4.3–5.9 mm (0.17–0.23 in)

Head

The face is yellow, moderately projecting, with a black median stripe in both sexes. The third antennal joint is sordid reddish below. The eyes are uniformly pilose."

Thorax

The scutellum entirely black.

Abdomen

Segment 1 is black and well-developed. Segment 2 is black or has a posterior margin that is red. Segments 3 through 5 are usually entirely red-orange to dark red in males. The superior lobe varies in shape and size, with an apex that is nearly truncate to strongly oblique, and with a length from one to two times that of the surstylus.

Wings

The wings are hyaline with a brownish grey stigma.

Legs

The legs are yellow and light brownish yellow. The basal half of the femora are black. The hind tibia is usually with apical half yellow-orange.
Females cannot be identified. [3]

Distribution

Palearctic: Fennoscandia south to Iberia and the Mediterranean basin, Israel and Turkey, Ireland eastward through Central Europe and Southern Europe (Italy, the former Yugoslavia) into European Russia. Nearctic: from the Yukon south to Costa Rica also in parts of the Afrotropical region. [8] [9] [10]

Habitat: Portugal.

Biology

Habitat: Unimproved grassland, heathland, garrigue, dune grassland, open areas and pathsides in forest up to the Larix/Pinus uncinata zone, fen meadow. [11] Flowers visited include umbellifers, Calluna , Jasione montana , Matricaria , Origanum , Polygonum , Potentilla , Solidago , Stellaria . [12] It flies May to September. The larva feeds on aphids on low herbaceous plants.

As "based on both morphological and molecular evidence", Paragus haemorrhous Meigen 1822, Paragus coadunatus (Rondani, 1847) and Paragus ascoensis Goeldlin de Tiefenau & Lucas, 1981 appear to be synonyms of Paragus tibialis (Fallén, 1817)". Rojo et al. (2006). [13]

<i>Syrphus ribesii</i> Species of fly

Syrphus ribesii is a very common Holarctic species of hoverfly. Its larvae feed on aphids. In common with many other species of hoverfly, males have the eyes meeting on the top of the head, whilst females have their eyes widely separated.

<i>Eupeodes corollae</i> Species of fly

Eupeodes corollae is a very common European species of hoverfly. Adults are 6–11 millimetres (0.24–0.43 in) in body length. Males and females have different marking on the abdomen; males have square commas on tergites 3 and 4, whereas females have narrow commas. Larvae feed on aphids. This species has been used experimentally in glasshouses as a method of aphid control, and to control scale insects and aphids in fruit plantations. They were found to be partial to the fruit, eating more fruit than aphids.
