Tufted Vetch is an odd plant: it grows in only a few places on my patch, but wherever it grows it is rampant. There appears to be no similarity amongst the places it chooses and there are places that appear to be ideally suited, but the plant is absent. It must have some very particular micro-climate requirements.

Taphrina alni is a parasitic fungus on female Alder cones:

Alder is a good food source for Sawflies: these are multiple mines of Acidia cognata. The broad-shouldered larva can be seen in each of the mines:

This next shot shows just how attractive Angelica is for insects at this time of year. I counted 7 ichneumonids, 2 sawflies and 2 dungflies on this flowerhead:

One of the few Ichneumons that can be identified by sight: Amblyteles armatorius, which is parasitic on larger moths.

Harvestmen are related to spiders, but they don't make a web. They hide instead in plants, waiting for some unsuspecting insect to come wandering along.

The social wasps are divided into two main families: Dolichovespula and Vespula. Dolichovespula species (Dolichovespula sylvestris shown) can be readily identified by the 'malar space', which is indicated by the arrow below:

The Potato Capsid, Closterotomus norwegicus, is commonly found on Knapweed and other composite flowers. I have never found it on potato:
