Neoascia podagrica (Fabricius, 1775)
Biology & ecology:
The small, semi-aquatic larva has been found in wet manure, cow-dung and wet compost. They seem to be able to utilise a wide range of situations where highly enriched, semi-aquatic conditions are present. Adults can be found in any habitat where there is lush vegetation, typically in hedgerows, woodland edge, gardens (where it is presumably breeding in compost heaps) and around the margins of water. They are typically found by sweeping, but will visit a wide range of flowers. Males hover near to flowers in bloom.
This is an extremely widely distributed and common species.
Status & conservation:
Trends indicate that a decline has occurred in the past 20 years.
