I've never really been very interested in Orthoptera. It's a small group so theoretically not much of a challenge but the identification criteria for a lot of species always seem to be a bit vague and comparative. This is all well and good when you're familiar with them but not much help to a beginner. Even the 'experts' seem to struggle with some species, I have a couple of cockroach specimens which are either Tawny or Dusky but I've shown them to various people and no-one has been able to definitively identify them.
Despite this I have managed to pick off most of the common species over the years, but Stripe-winged Grasshopper had eluded me. The opportunity of a meeting near Dorking on a warm, sunny day encouraged me to pay a visit to Box Hill. The grasshopper was very easy to find (although not a very cooperative photographic subject) but there was little else of interest on the slopes.

Back at the Zigzag car park I noticed a couple of groups of an unfamiliar plant. It really should have been easy to identify as the leaf-shape was very distinctive but the flower wasn't right. Eventually it was resolved as Buckwheat but I maintain that the picture in the Collins guide is very unhelpful. Buckwheat is a member of the sorrel family and they illustrate very sorrel-like flowers, not at all like this:

A quick stop in at Chiddingfold Forest produced little of note apart from the larval case of the moth
Coleophora discordella on Common Bird's-foot Trefoil. This is not a rare species but I've only found it in the larval stage on a couple of occasions.

There has been news recently from Dungeness of two very unusual Orthopterans. The Sickle-bearing Bush-cricket which was resident for a while at Hastings and the Italian Tree Cricket which has not previously been recorded breeding in Britain as far as I know. I had a couple of work related things to do in Kent so an evening visit to Dungeness seemed in order. I had fairly detailed info on where to look for the Italian Tree Crickets but the best chance of them was when they start singing at dusk. I did have a grid reference for the Sickle-bearers but it was worked out from aerial photo's rather than being taken at the time. I spent some time looking for these without success, a couple of hoppers and an interesting looking beetle may be new for me when I get them identified but the only new species for me by dusk was New Zealand Spinach - a plant so boring I am not going to post a photo.
As dusk fell the Italian Tree Crickets started to sing. It was really rather bizarre to be standing at Dungeness in a cold wind, listening to noises that would not be out of place in the tropics. There were a good couple of dozens crickets singing but actually seeing one was proving to be rather difficult as most were hidden deep in brambles. I did get one brief view but the photo's that I took were all horribly out of focus. At this point the warden of Dungeness Bird Observatory arrived and he kindly took me to see the Sickle-bearing Bush-crickets (well, cricket singular while I was there). It turned out that the grid reference I'd been given was a good 100m+ out.

I returned to the tree cricket area and eventually they became more cooperative (or I became better at finding them).

Also of Orthopteran note was a mating pair of Lesser Cockroach.
