Emmelina monodactyla is one of the Plume Moths. These have wings that retract like a venetian blind when the moth has landed. A system of hooks and eyes keeps the wings in shape when in flight. I haven't worked out a benefit for this complex system, other than a very narrow profile when resting.
Another Episyrphus balteatus hoverfly that initially appeared to be looking for aphids, but this one was nectaring on the recently-opened Meadowsweet.
Greater birds-foot Trefoil has opened. I used to think that I had some Greater mixed amongst the ordinary, but every specimen that I have examined locally turns out to be Greater. Ordinary Birds-foot Trefoil is earlier and, in my experience, more coastal.
