Species text
Solva marginata is essentially a fly of southern England, though with scattered records as far north as Yorkshire. It is fairly regular in southern old woods with about 25 known post-1960 sites known to Falk (1991). The species is now known to be less uncommon than previously thought. The larvae develop in the rotten wood or beneath sappy bark of a range of broadleaved trees, especially poplar and aspen, but also including sycamore, oak, ash and walnut. Fallen trees are preferred, though it would appear that live trees with some dead bark can be exploited. Any post mature or dead trees within a site should be retained, ensuring continuity of these in the future. References
