Species account from Provisional atlas of British hoverflies, Ball & Morris, 2000.

Parasyrphus annulatus (Zetterstedt, 1838) Syrphus annulatus Zetterstedt in Coe (1953)

Biology: Larvae not described, but larvae of this genus are usually arboreal predators on adelgids and pine aphids. Normally found in larger woods, usually with some coniferisation. Adults are generally found visiting flowers, or settled on sunlit vegetation and are fairly distinctive, being noticeably smaller than other black and yellow syrphines

Distribution: Very local (but sometimes abundant where it occurs) in woods in southern and central England, with scattered records throughout most of mainland Britain, north to south-east Sutherland
