Down House bird survey today , but on the way , a quick stop on the Common at the Ash tree , revealed 5 Purple Hairstreaks , all up high and some already moving off into surrounding Oaks . A freshly emerged female Marbled White did show off well the golden leading edge to her forewing . The survey at Down House was done in very warm , humid conditions , and it wasn't a surprise that only 15 species were recorded . The best of the bunch was this Yellowhammer which wouldn't let me get any closer . Once again , it was butterflies that filled the gap , 12 species being recorded during the visit . But it was a Silver Y moth that was first to the camera , usually a very timid soul , diving into vegetation at any opportunity , this one forgot about all that and posed on the flowers of Sage in the walled garden . As soon as I got into the large meadow , I started recording Small Coppers , all looking very fresh , and all 8 probable males as they were already scrapping amongst themselves . Not so many Skippers as at other sites , just 4 recorded , but I thought these two Small specimens , male below , were going to get it together , but they didn't . On the lsat survey , I recorded a pristine Dark Green Fritillary , and today I recorded one too , possibly the same specimen , but definitely not so pristine now . The big numbers of course were Meadow Brown (163) and Ringlet (61) , but Marbled Whites were disapointing , with just 13 being recorded . It could well do with the meadows being cut far too early in my opinion last year . On the way around , three Violet Helleborines were found in the Sandwalk Wood , one a very robust plant , and a few flowers of interest found were ,Marjoram/Origanum vulgare , another Labiate , is just flowering ,Feverfew/Tanacetum parthenium , a member of the Daisy family ,Corn Marigold/Chrysanthemum segetum , another Daisy and a shot of a single flower of Wild Basil/Clinopodium vulgare , another Labiate .
And finally , one for the detectives . I found this pair getting it together in the large meadow .

Sunday 3rd. July 2011

After all the excitement of recent days , it was back to the mundane things of life today , like taking Carol to do the monthly shopping , but , before that I did spend an hour or so up on the Common , hoping for another meeting in the early morning light with the Purple Hairstreaks . Trouble was that no one told the PHs , as the only ones I saw , about 10 in total , were high up in the Oaks , seemingly unwilling this morning for a photo shoot . The usual more common species were recorded , along with a single Marbled White , the first recorded on the site this year , still warming up amongst the grass . A single , very fresh , second brood Holly Blue was also recorded , but quickly disappeared over a high fence .
After the shopping and a quick coffee , I headed for the Farm lake , taking advantage of the sunshine . Still no sign of the Little Grebes at all , and the 'Coot 8' are still intact . Still not great numbers of Odonata , but several of the bays had male Emperors patrolling their territories . Black-tailed Skimmer numbers seemed lower as was any mating activity , with most males perched over their patch , waiting to drive off intruders . Around the banks , Purple Loosestrife/Lythrum salicaria is starting to flower , which will boost nectar sources now that the masses of Ox-eye Daisies have gone over . As will Wild Carrot/Daucus carota , one of the many umbellifers found around the lake , and a magnet for many of the smaller insects . I meant to mention on yesterday's post that I found my first Gatekeeper whilst searching for the Black Hairstreak , and today three more were recorded , all males , identified by the dark sex brand on the top of the forewing . In the quietest corner of the lake , I found one of three female Emperors , two of which were ovipositing , secreting their eggs singly into vegetation around the shallow , warm edges . She was very mobile depositing her eggs over a large area , whilst I stood quietly watching her . Eventually she chose a spot directly in front of me , giving a good view of the dark dorsal marking running the length of her abdomen , the only dragonflies to be so marked . Still lots of newly emerged Common Darters amongst the vegetation , but only small numbers of Common Blue , Azure and Blue-tailed Damselflies were recorded . The lady of the house came down for a chat and invited me to go up to the stables where the Swallows are nesting if I wanted to before leaving , which I duly did . On the way up the drive , two juvenile Jays were on the verge and I slowed to get a shot , even though I still had the 100mm. lens on the camera . I tried to get close but every time I crept forward 5 metres , they flew back 6 metres , and one flew off . This was the best I got of the one that remained . Arriving at the stables , I set up the tripod at the stable door , but there wasn't much action at the nest , which has been used for at least the last 4 years . Eventually , two little heads peeped over the edge to see what was going on . A few times adults did come to the nest , but not with food in their bills , even though the youngsters were begging . On other occasions , the adult would just hover in front of the nest , then perch and watch the actions of the youngsters . Then different tactics , as the adult landed next to the nest , calling constantly . That too was followed by perching some way away and watching again . Those two youngsters looked ready to fledge to me , and I think that the adults were trying to encourage the pair out of the nest and into the wide world outside . As I packed up to go home for lunch , the two youngsters were still entrenched in the nest , still begging for food . I don't think that they will still be there tomorrow though .

Whilst photographing the male Purple Emperor during the week , the other chap , with the walking stick , mentioned that he had been to see one of the rarest and most elusive butterflies the day before , and had found it . A quickly arranged sorti was planned last night , and I met Keith at his house at 0600 to see if we could do the same . Our target species was the Black Hairstreak , a species restricted to just 45 colonies , all in the East Midlands , between Oxford and Peterborough , and today we were heading for Glapthorn Cow Pastures in Northamtonshire . We had an easy trip up , and even before reaching the reserve , just had to stop the car to get shots of Red Kites , cruising effortlessly over the open fields . We found the site and nervously , as neither of us had ever seen the species in real life , started to search the large areas of Blackthorn and Bramble , paying particular attention to those that were already swathed in the warm sunshine . With many large , mature trees on the site , as the sun rose in the sky , different patches came into the sunlight , as others went back into shade . A deer was seen at distance down a track as we arrived , and during the first couple of hours , at least two were heard 'barking' for long periods . It didn't click till later , that the 'barking' was probably Muntjac Deer , as they are well known for doing so and also found records of their sighting in the visitor's book on site . We were finding plenty of butterflies , but not the target species , and although by the book we should be in the middle of their short flight time , like all other species this year , they probably emerged early . This was also confirmed in the visitor's book with a 28th. May entry of 'first Black Hairstreak seen' . From the open glades we still had occasional views of Red Kites and the book once again informed us that they had in fact nested on the site this year . Three hours of searching still hadn't produced the required result , but it also gave more time to practice Volucella pellucens in flight shots , and when they weren't around , the odd spider managed to make it to the camera . Like everywhere else this year , Large Skippers showed really good numbers , here three posed in line astern . Yet another Red Kite flew over the site , this time looking a bit tattier than the others . Searching hard and trying not to let our lack of success get us down , after about three hours Keith uttered the words 'I've got a Hairstreak' . I don't know how 'Eagle Eye' saw it as it was well back in a large Bramble patch and above head height , but I'm really glad that he did . Then came the soul searching , is it definitely a Black , as the White-letter Hairstreak is very similar . Frustratingly , it seemed to prefer the Bramble flower on the far side of the plants , being out of sight for much of the time . Every now and again , it gave a full side-on view , and sometimes that view was in full sunlight . It was then that we started to believe that we had found our target species . Because of the distance , it was difficult to see the orange and black makings on the back of the hindwing , carrying on and fading out on the back of the forewing , but the inner row of black spots on the hindwing was the clincher , it was the only one we saw , but it was the species that we set out to see , well spotted 'Eagle Eye' , a first for both of us . Whilst we were photographing it , a couple from Hampshire , who had just arrived on site to see the Black Hairstreak , reached where we were standing , and saw their target species within 10 minutes of arriving . We made our way back to the car for a well earned sandwich and drink

and talking about making our way back home , delayed by a rather tatty Common Buzzard overhead as we left the wood . At the car , we met another couple who asked if we had seen BH , and we told them the story . They told us that they had just come from another wood a short distance away where Purple Emperor were seen . After lunch , plans changed to a quick look at the other wood as it was close by . On a track through farmland , yet another Red Kite encounter . Just before reaching the other wood , a young Fox decided to play 'chicken' down the lane in front of the car , which went on for a couple of hundred metres , before it decided to dive off to the side .
By the time we started looking around the second wood , the cloud had started to build , and the sun was at a premium . But , in one short spell of sunshine 'Eagle Eye' again worked his magic , spotting a female Purple Emperor which flew overhead and settled in a Willow . Plenty of White Admirals and a couple of White-letter Hairstreaks were also seen , but things got steadily quieter . With a long trip home , we decided to call it a day , with a total of 18 butterfly species seen , including 3 Hairstreak species , 5 raptor species , including Hobby and probable Goshawk .

Friday 1st July 2011

Whilst in a 'purple vein' , I made a point of making an early visit up on the Common for my local 'purple' , the Purple Hairstreak . Despite perfect conditions , the Ash tree showed no movement apart from the breeze . Eventually , I saw three PHs , way up high , but one did fly down , almost circling me in the glade . I offered the tripod , but it turned and flew back high into the Ash . I decided to look at other sites , on the adjoining West Wickham Common . The first , which was a super site a few years ago produced no sightings . The second , almost overlooking my house produced 8/10 PHs , but all well up in the large Oaks , and not willing to come down . I had promised Carol to take her to the shops at 0830 , and that time was quickly approaching . My last chance , near the ancient earthworks , on my way back to the car , then produced the goods . At first , it was just a single PH , but , down on the Bracken , it posed for me . then , looking around , I spotted two more . They had dropped down from the Oaks that were still in the shade , to warm up on the Bracken that was already in the full sun . The first was an almost pristine male , which , after opening and closing it's wings , finally posed to reveal his full glory . A couple of minutes later , a pristine female descended from the Oaks , and not to be outdone , showed her stunning topwing . It was already o835 , so , a quick exit to the car , and yet another late meet up to go shopping .
Having done my duty , I left Carol to potter in the garden , whilst I headed to the Burnt Gorse area of High Elms , to check on my local species , which once again this year , will be visited by Butterfly Conservation , Kent Branch on Sunday 24th. July . First stop was at the Violet Helleborines , which , I'm glad to say are still in good condition , with the first flowers looking as if they will open next week . In a sunny Bramble patch on the other side of the track , three White Admirals were scrapping over enough Bramble flowers to support thirty , but in the dappled sunlight , although I may sound biased , did look smarter than those seen recently . As I left the three to their scrapping , and about to head up to Burnt Gorse , a Roe buck wandered nonchalantly from the woodland on the opposite side , before seeing me , and making off at warp factor into the distance . I still had the macro lens on the camera , so couldn't manage anything better . The glade where most of the Honeysuckle is to be found was surprisingly quiet , but one probable female White Admiral did put in an appearance for the camera . Walking back through the woodland , I was able to do a bit of broadcasting , not on the radio , but making sure that next year's Bluebells will be as good as this year's , dislodging the now ripe seeds from the open seed heads as I walked along .
I approached Burnt Gorse from the path that passes the small glade , leading to the 5 bar gate , and spotted a butterfly fly up to , and perch on one of the trees in the small glade . It turned out to be my first female Silver-washed Fritillary sighting of the year . This is the only British butterfly to lay it's eggs on the trunks of trees , albeit that the foodplant , in this case Violets , are found around the bottom of the tree . On hatching , the caterpillar will make it's way down the trunk to the Violets . When she moved off , I found the egg that she had just laid . The female was resting nearby , identified by the much more sombre overall colour , and the lack of the four dark markings across the forewing , sported by the testosterone charged males .
In all , 8/10 SWFs , impossible to be totally accurate as the males are so mobile , and 7 White Admirals were recorded .
Other interest included , a very fresh probably second brood male Common Blue , a male and female Brimstone , both probable new brood . I had hoped to find a mating pair of Marbled Whites , but , even after following a male as he searched relentlessly over Burnt Gorse and failing to find a female , I thought , what chance have I got , and made my way back to the car park .
As I passed the area where the Roe buck had appeared from , and also the area where the Violet Helleborine are growing , I stopped to check the latter , and was pleased to find them still intact .
