The large, attractively marked hoverfly Helophilus trivittatus is quite conspicuous at present, especially around Hemp Agrimony. There are several in our Fairlight garden most days , usually on this plant or basking on sunflowers [which obligingly turn towards the sun]. Today I saw quite a lot in Hastings Country Park NR,, on Hemp Agrimony by Ecclesbourne Glen steps. As I looked at these, one flew into a spiders web and was immediately trussed up and dealt with. Being something of an arachnaphobe I’ve never “got into ” spiders, but I imagine this one is common.
