Some blackthorn, Prunus spinosa, bushes nearby have been 'infected' with Eriophyes similis. There is nothing unusual in that, but I have never seen such an overwhelming attack.

The galls created by this mite were on every leaf with, as is usual, most formed at the leaf edge and although galls normally have little if any effect on the general health of the host an infestation of this magnitude must surely be debilitating.

Oxford Ragwort, Senecio squalidus, had colonised waste ground, its golden flowers much appreciated by insects seeking nectar. The story of this species, with its remarkable, spread across Britain has been well-documented and I have told the story elsewhere in these blogs.
On waste ground nearby I was pleased to find Honesty, Lunaria annua, in full flower. Despite its specific epithet of annua it is a biennial. This popular garden plant is a member of the Cabbage Family, Brassicaceae and, like many other species in the family such as Oilseed Rape, Brassica napus, subsp. oleifera, it yields oil.
It is not yet, as far as I am aware, being grown commercially for this purpose but the oil from Honesty would appear to have valuable potential both medicinally and as a specialist lubricant. What a lovely sight a field if it would make!

It is closely related to Groundsel, Senecio vulgaris, and the hybrids arising from these two species are highly complex. So far I have not knowingly encountered any of these hybrids.
Growing nearby was yellow-flowered Yellow Corydalis, Pseudofumaria lutea. It is frequently encountered in towns where it often colonises brickwork and I only mention it because I have, in the last few days, planted its less common relative, Pseudofumaria alba, in our front garden.

The leaves of Creeping Buttercup plants, Ranunculus repens, were being mined by the fly Phytomyza ranunculivora. As is often the case the species could only be determined by the distribution of the frass (poo) in the mines. I do have an exciting life!

Earlier I said that wildlife was taking advantage of the situation and sometimes it does this in remarkable ways. A solid brick wall has, at one point, been pierced by a blackberry bramble, Rubus fruticosus, and will, given time, split the structure asunder.

This doesn't matter as the whole site is due for redevelopment in the near future. And hopefully we'll get a new library!
