Leucozona lucorum (Linnaeus, 1758)
Biology & ecology:
The larva preys mainly on herb layer aphids. Adults fly in dappled sunshine in situations such as woodland rides and edges, roadside verges and hedgerows, where they are often found in association with Red Campion Silene dioica and Greater Stitchwort Stellaria holostea.
One of the characteristic hoverflies of early spring throughout lowland Britain, with an earlier flight period than the other Leucozona species although it appears later in Scotland. There is some evidence of a partial second generation with occasional records to September.
Status & conservation:
The frequency of occurrence has fluctuated widely, but the trend is marginally downwards.
