There are around 7000 species of Diptera in Great Britain and we know their diversity in the garden is currently massively under recorded. Identifying many of the species is difficult, as indeed is obtaining a clear photograph of them.

As flies in the garden go, the hoverflies are perhaps the most comprehensively recorded family of flies (Syrphidae), due in part to our own growing interest in this family and the relative ease of identification (and help available to identify them).
