Black and Brown Hairstreak larvae at Ditchling Common

Brown Hairstreak larva, Thecla betulae
Yesterday I visited Ditchling Common to attempt to find Hairstreak larvae and pupae. I found a Brown Hairstreak larva (8mm) on blackthorn, munching on the new growth at the tip of a branch. It started moving down the branch and when I returned later it was nowhere to be seen. I met Ben Greenaway on a similar hunt and he showed me a Black Hairstreak larva he had previously found. David Cook directed us to the Black Hairstreak pupa he had located on a branch and then Ben found another on a nearby leaf. There were numerous moth larvae on the blackthorn and oaks and I have six which I cannot as yet identify. I also spotted a Plum Tortrix moth (Hedya pruniana) and a Mottled Umber larva (Erannis defoliaria). In the nettles by the car park were numerous Red and black Froghoppers.

Damselflies at Highdown Gardens

Large Red Damselfly, Pyrrhosoma nymphula
Yesterday we had a walk round Highdown Gardens which is always lovely, especially at this time of the year. It has a wonderful variety of garden habitats with a worldwide collection of flowering trees and plants. My favourite spot is the pond which had plenty of damselflies, with many mating pairs - Common Blue and Large Red Damselflies.
  Last week we had a Nut-Tree Tussock moth (Colocasia coryli) on our balcony and yesterday two pugs: a Channel Islands Pug (Eupithecia ultimaria) and a Common Pug (Eupithecia vulgata).

Celtic Ring Money and a Derbyshire visit

On Thursday I attended a dig near Whitchurch, Hants and was delighted to find a rare artefact, a piece of Celtic gold Ring Money weighing 3.88g. This will go through the Treasure Process with my FLO (Finds Liaison Officer). I also found a gilt Georgian watch winder (18th C).

I then drove to Buxton to attend a dig in Derbyshire. While there I visited the Buxton museum to attend an exhibition of Hoards found in Britain, a fascinating experience. I took photos of the exhibits: https://www.colinknightimages.com/Blog-slideshows/2019/Hoards-a-hidden-history-of-ancient-Britain-at-Buxton-museum/ I also visited Aunt Bea and we had a lovely Italian meal at a local restaurant. The metal detecting was disappointing so I came home early and attended a local dig and found a Roman grot (grotty copper coin).

I think this is a Light Knot Grass larva (Acronicta menyanthidis). I found it on a dry stone wall.
