I looked through my hoverfly records to see what I should be seeing and to see which of those that I have seen are the most noteworthy.
First those that I have seen and later I’ll look at what I am missing but a quick glance told me that many that I’m missing are in grassland, woodland and wetland so next year I’ll look outside the garden. This is from the maps and status as given in Ball & Morris: Britain’s Hoverflies.
Many of these species are waiting verification (e.g. Riponnensia splendens looks a bit suspect judging by its scarcity in Scotland).
