First up the moth. As I was walking along the path at the bottom of the top reservoir I spotted a small moth with very long antennae flying around a tree. I watched it land and managed to get a couple of photos. Checking my book at home I found out it's called Nemophora degeerella, a species belonging to the Adelidae family (known colloquially as Longhorns), which is made up of 15 species in the UK. It's common throughout England, so I expect I'll see more examples later in the year (details here).
There weren't many other insects about (that I could photograph or identify!), but I did spot this Red and Black Froghopper. This is a common species at Linacre and I see them on most visits during the summer.
