Species details

Leucozona glaucia (Linnaeus, 1758)


Syrphus glaucius Linnaeus in Coe (1953).


The larva preys on herb layer aphids. A woodland species, typically found in clearings, rides, and tracksides, but also in tall vegetation along roadside hedgerows, scrub, etc. Adults are usually seen visiting flowers, especially white umbels such as Hogweed Heracleum sphondylium and Wild Angelica Angelica sylvestris.


Widely distributed in well-wooded lowland areas throughout Britain, but possibly more of a northern and western species than L. laternaria. The gap in distribution in eastern England and East Anglia appears to be genuine, and not an artefact of recorder effort. Where it occurs it can be extremely abundant; this is very evident in northern and western areas where it continues to form a significant part of the 'Hogweed fauna'.
