Heavy rain.
I've been watching this tree on the river for a year or so, and I now think it's a Bird Cherry - Prunus padus. Well, Gill does, and I'm not arguing. The fruit will tell.
And on the putative Bird Cherry we have galls of Eriophyes padi, caused by a mite.
Notice that the young galls are just beginning to crease the leaf, but the more developed galls have caused substantial distortion.
Rather confirms the id, I think.
Hawthorn blossom is about 2 weeks later than last year, so we're still behind.
Red Campion - Silene dioica - is common in a few places, but is missing from places that look just as suitable. Maybe it has strict or subtle environmental requirements.
I was taken by the extremely long legs of this crane fly.
The parasitic hymenopterans are beginning to appear in numbers. This one was running quickly all over the top and under surface of leaves looking for a host.
A yellow snail. I have no idea of identity.
And I'm going to leave this as a mystery picture for a day or so. I found many of these strangely-shaped objects perched on Butterbur leaves, and it took me a little while to work out what they were. They're about 1 cm. tall and the time of year is a strong clue to the identity.
