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).

Bronze Age 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 Late Bronze Age gold 'Ring Money' weighing 3.88g, 14mm outer diameter. This will go through the Treasure Process with my FLO (Finds Liaison Officer). Their use is unknown and debated, they may have been used as currency or jewelry or both - see 

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.
