Swarms of Migrants in Hastings Country Park.

In the past couple of weeks there have been migrants lurking in the undergrowth wherever you looked. One of the large and brightly marked hoverflies, Scaeva pyrastri, has been seen on just about every umbel of hogweed in the hedgerows around the Country Park. It is a large black and white fly with comma shaped markings and a bulging face, making it easy to identify. It is not resident in Britain but is a very frequent summer visitor, with some years seeing huge numbers of migrants. This is one such year.
