Bramble bushes in particular are insect magnets. Here's one in a wooded area so protected from wind, and it was alive with bees.
This looks like a male Vestal Cuckoo Bee (bombus vestalis). It has the distinctive yellow tinge to the edge of the white tail, and has a band round the top of the abdomen.
This and the one below look like a female Vestal Cuckoo Bee (no middle ring).
I don't know which this one is. It is a female worker bumble bee (has pollen baskets) but has no middle band.
This is a worker (pollen baskets again) and is straightforwardly either a buff-tailed bee or white-tailed bee.
Then a couple of hoverflies, both of which are I believe Volucella Bombylans. These mimic bumble bees, the first one mimicking red-tailed bee and the second white-tailed bee.
Now on easier ground. A male Large Skipper - first of the year.
Finally a Whitethroat, and then one of the more notable birds of the patch. Please leave a comment when you have found it!
