In the hedgerows wild roses are coming into bloom. The only species present was the Dog Rosa, Rosa canina. Perhaps I shouldn't use the word 'species' as this lovely plant is really a complex aggregate whose different forms are to be distinguished only by an expert.
Dog Roses have little fragrance but their simple beauty is unsurpassed.

Some claim that it was originally called 'Dag Rose' on account of its dagger-like thorns. As kids we would grind up the seeds - or use them whole - as 'itching powder' but I'm not sure the were really much of an irritant. During the war we collected the hips to be taken into school and weighed. We earned a few coppers this way. The hips really are very rich in vitamin C and I believe that it is still possible to purchase Rose Hip Syrup.
At the base of the hedgerows Ground Ivy, Glechoma hederacea grew and I was pleased to find one specimen bearing an impressive gall. As is often the case it was the work of a gall wasp, in this instance Liposthenes glechomae.

Distribution maps suggest that it is widespread but not particularly common. The gall is more frequently recorded than the actual wasp.
A speculative sweep with my net captured an interesting geometrid caterpillar (in America they are called 'inch worms'). It turned out to be an Angle-barred Pug, Eupithecia innotata and is another widespread species.

This is a variable insect, so variable that different forms were once thought to be different species, and I must admit that I spent over an hour examining various features of it before coming to a decision regarding its identity.
In my previous blog I mentioned Yellow Rattle and commented on it being a hemi-parasite on grasses. The area where I was recording today contained a great deal of this ecologically important plant and it was interesting to note that, where it was abundant, few grasses flourished.

Yet in an area barely a metre away, devoid of Yellow Rattle, grass was growing strongly. It illustrated forcibly what a dramatic effect even a hemi-parasite can have.

This was a splendid visit and once again I was struck by the effects of a thoughtful management regime. Let's hope that this is the start of a developing trend, allowing nature to recover from the shocking agricultural methods of the last half century.
