Tuesday 12 June

I've been very busy mapping the distribution of the now famous Black Hairstreak population of Ditchling Common, finding the species in all suitable habitat as far north as Janes Lane, about 1.3km north of where David Cook first discovered it. Here are some of my favourite images collected along the way (6 - 11 June). (Neil Hulme)

You can never have too many pictures of Black Hairstreaks on bracken in Sussex so here are some more. It's almost more about the composition of the bracken than the Hairstreak. Anyway, fun day with plenty of afternoon Hairstreak action and plenty of chat with Sussex stalwarts of lepidoptery! Nice to put faces to names and bump into combinations of the two (hello Trevor, Neil again!)Thanks to Dave of course - both for the Hairstreaks and his contribution to the environment; think of all the petrol that won't be burned on trips to Oxfordshire, Cambridgeshire and Northants for ever more or at least as long as this magnificent colony lasts! (Rolf Farrell)

My apologies for the delay in getting this sighting in! However, on 10 June on Seaford seafront, at about 14:30, I saw a very small greyish butterfly with pale underwings come in/off the sea and disappear northwards; about the size of a Common Blue and a similar although more delicate and erratic style of flight. It looked very much like a Long-tailed Blue from my brief view, but hard to say for certain. Thought it would be worth letting people know, just in case it's a harbinger of another good year for this species! It was a gentle southerly airflow on Seaford Beach on Sunday, ideal for immigration. (Liam Curson)

Great spelling of the moth name. However Bob Eade points out that it is in fact a Privet Hawk-moth! (Ed jnr)

Day two at Ditchling common saw fewer Black Hairstreaks today, owing to constant cloud cover.
In spite of the cloud some very fine specimens were found, and quite a few old faces turned up
to enjoy the latest Sussex species.
One image, with wings part open, the orange spots on the upper side of the hind wing can just be made out. (Trevor Rapley)

Just a small collection of photos to follow up report of sightings from Iping and Stedham Commons on 11 June 2018. (Anthony Bennett)

During a recent visit to Ditchling Common I saw many Black Hairstreaks. There were also Brown Silver-lines (Petrophora chlorosata), Garden Grass-veneers (Chrysoteuchia culmella) and a Variable Damselfly. At Littlehampton I found a Small Dusty Wave (Idaea seriata) on our outer door. (Colin Knight https://www.sussex-butterflies.org.uk/news/#76)
