Parasyrphus malinellus (Collin, 1952)

Identification

Identification difficulty = 4. microscope_icon camera_icon_cross according to Ball & Morris, 20241

Synonymy

Syrphus malinellus Collin in Coe(1953)2.

Biology

The larva is undescribed, but larvae of this genus are usually arboreal predators of adelgids and pine aphids. Adults are found along rides in conifer plantations, and in partially-coniferised deciduous woodland, where they fly amongst the conifer foliage at some height, descending to visit flowers.

Flight period

The following plots show the number of unique records per week that were not reported to be of eggs, larvae or pupae. phenology

Distribution

Described as new to science in 1952 on the basis of British material caught between 1932 and 1942. It occurs widely across Britain and is now known to be much more abundant in Scotland than data suggested when the Provisional Atlas (Ball & Morris, 2000)3 was published. dotmap
