Quite a number of the hedges around the fields here are Blackthorn, Prunus spinosa. They have white flowers at this time of year, but I have never seen them flower so profusely.
The Cherry trees are also flowering well this year.
The flowers are alive with insects. This lovely Carder Bumblebee, Bombus pascuorum, was on a Cuckoo Flower, Cardamine pratensis, in a meadow near where we live.
