Sunday 23rd.May 2010

I decided to do the High Elms butterfly transect this morning , but on the way , stopped off at the old farmhouse where the House Martins have been very active as I have passed . I got some shots , but will post them in the next few days , whilst volunteering , three days at least this week , or this post will never end .
The temperature was already 16C when I parked up in the Golf Course car park , and crossed over into the conservation field side . Almost immediately I recorded a Red Admiral , and from it's jizz , a probable female looking to oviposit , but I could not get near enough for a shot and she was soon away . In the same triangle of uncut grassland was a Small Copper , another female I think , with the same agenda as the Red Admiral . As it was still morning , Goatsbeard-Tragopogon pratensis , commonly known as Jack-goes-to-bed-at Noon or Sleep-at Noon , referring to the flower's habit of shutting about midday . Easily overlooked as a Dandelion , but the green bracts are always longer than the yellow petals . Later , a pappus or clock , much larger than the Dandelion will be formed . Also , amongst the grass were several Mother Shipton-Callistege mi , so called , after the profile of a witch that appears on both forewings . Look for the eye on the left wing , then find the nose and chin of the witch . Just before entering the fenced Conservation Field , I recorded the first of the year Common Blue for the site , and in the fenced off area , the first Small Heath of the year . Several more male Common Blues were recorded in the bottom corner , along with a mating pair of Dingy Skippers , sorry you were working Keith ! The walk up to Burnt Gorse provided the less often seen side of a Speckled Wood , normally seen basking with wings open . Burnt Gorse itself produced lots more Dingy Skippers amongst other species , and as I was about to leave , I came across a pair of mating Common Blues . He obviously didn't hang about , I hadn't even seen a female till then . As I turned away , I noticed a couple by the bench with binoculars and camera . I asked if they were after butterflies , and Green Hairstreak was the reply , which they had already found . I pointed out the mating Common Blues , and they took their shots . Standing chatting about butterflies , a white flash passed us and landed in the grass . I went over and took an underside shot , as vegetation prevented a topside shot . As we had got as good as we could , I thought I would try the old finger trick for the first time this year to which the lady asked , ' are you Greenie '?
As it happens , they read this blog , and came looking for the Green Hairstreaks that I had mentioned . Oh , the moth by the way is a White Ermine-spilosoma lubricipeda .
Leaving them in the sunshine , I headed for the woodland to check on the Birds Nest Orchids . The number at the original site has doubled , to two , most disappointing . On my way to the new site found by Keith , I found a single under Beech , and lots more White Helleborines pushing through the leaf litter . It is going to be a good year for them . At the new site , 22 counted last visit , a magnificent count of 33 was made , with good chances of more to come , as some are just pushing through . The oldest ones are now in flower , using the word liberally . As I made my way back to the transect route , I found lots more White Helleborines and , by the side of one of the main paths , 3 more Birds Nest Orchids . The last butterfly species recorded was a single Peacock , on the bridleway back to the car park .
In all , 14 species were recorded - Small Copper (1) , Red Admiral (2) , Common Blue (15) , Large White (5) , Orange Tip (2) , Green Hairstreak (2) , Small Heath (1) , Dingy Skipper (24) , Grizzled Skipper (1) , Speckled Wood (5) , Green-veined White (1) , Brimstone (4) , Small White (1) and Peacock (1) .
Before getting in the car , I had a quick look at the dipping pond . Lots of damselfly activity , mostly male Common Blues , and lots of Large Reds , either in 'tandem' , or as many were , in the 'praying position' , with the male still clasping the female behind the head , as she inserts her eggs into plant tissue , which protects them from predators . Sometimes , she will walk backwards down the stem , and under the water surface whilst doing so .
By now , I was well cooked , and headed home for a 'cool' lunch .

Saturday 22nd.May 2010

Firstly , a moth photographed by Keith yesterday on our Duke of Burgundy trip . Small , but with distinctive markings for someone in the know , Dean . Keith would be obliged for some help.



Another very hot day , so I decided to get out reasonably early , dropping Carol in town to do the weekend shopping , whilst I made a quick visit to South Norwood Country Park , to check out a Great Spotted Woodpecker nest site that Keith had passed earlier in the week , during a lunchtime walk out from work . He had described the location , and as it was quite close to the road , ideal for this quick visit . From 10 metres away , you could hear the constant racket of an unknown number of juveniles , emanating from a hole 6/7 metres up a Willow . It wasn't long before the first adult arrived at the tree with a bill crammed with food , took no notice of me , my camera and tripod , set up below on the path , and started feeding one of the youngsters . This species of Woodpecker would lay 4-7 eggs in a single brood . The male flew off , and a few minutes later , the female arrived , with her food for her ravenous brood . She took up position just slightly lower and to one side of the hole , enabling a sighting of one of the racket makers , which looked as big , if not bigger than her . The pair continued backward and forwards with food , and every now and again , the female , after delivering her food , squeezed into the hole to do a bit of housework , bringing the rubbish out with her . The incessant racket got louder every now and again , as one of the youngsters ventured to look at the big world outside , still calling for more food . I could have stayed all morning , but Carol waiting with the shopping might not be too pleased , so I left the family to it , but I cannot say in peace .
A cup of coffee on returning home , then off for a look at Spring Park Pond . Still very quiet for damsel/dragonflies , just 4 male Large Red Damselflies were recorded , all in perfect condition , unlike the posted last weekend . A single Orange Tip and 3 Large Whites were also recorded , and whilst there , Common Whitethroat , Blackcap and Chiffchaff were all in full song .


I made one more visit before lunch , to the Farm Lake . As I arrived , several Swallows were skimming the water , but unfortunately I had the 100mm. lens on , and they were some way off . Around the banks , Oxeye Daisies have opened in good numbers since my last visit . The only Damselflies seen , were good numbers of teneral , freshly emerged specimens , taking their first flight , and not coloured up enough yet for positive identification , but I would expect them to include Azure and Common Blue , and Blue Tailed to be amongst them . Large Red were also recorded here . Butterflies were few , just a single Brimstone male and a female Orange Tip , which I followed as she nectared on Ragged Robin , then stopping to examine a single Garlic Mustard/ Jack-by-the-Hedge plant . As she hovered around the three flowering stems , I thought , yes , she's going to lay . But , she never did settle or lay , and flew off much to my annoyance . After she had gone , I examined the three sets of flowers , and found an Orange Tip egg on each of them , further enforcing the 'cannibalistic caterpillars' statement . If you remember , when I saw the other female lay her egg and then found it , it was white , but as the eggs mature , they turn this orange colour . This particular plant is growing on a large felled tree trunk , so is easy to find , and I will try and post the caterpillar , and possibly the chrysalis , when they appear . No sign yet of the Little Grebe family , and bad news for the female Mallard , as she has only one ducking from her original 12 . One of the young Coots seems to be gone as well . Most likely cause for all losses would be Grey Heron , the Kelsey Park heronry is not far away , and the are often seen in the shallow water , and Foxes , of which there are good numbers in the area . A last look around the lake before leaving gave a surprise , a male Mandarin . Then , beyond him amongst the Lilly pads , a female . Another movement close by turned out to be a duckling . It took 10 minutes of stalking to get a shot of all three , and when I did get it , the male looked as if it had been pulled through a hedge backwards . The species usually has a single brood of 9-12 , the nest being in a hole in a tree . The last time I saw a female on the lake , she had about that number of young with her , but I only saw her the once , and that was a couple of years ago . Perhaps this pair have encountered the Heron or Fox ? That might also explain the state of the male , trying to defend his family .

The jury is still out on last night's raptor , 2 for Honey Buzzard , 3 if you count me , and one against . I've never seen one before , but it was definitely different to Common Buzzards that I have seen .

Friday 21st.May 2010

Buoyed up by our success yesterday in overcast conditions , Keith and I set off in glorious sunshine , to complete the search for the postponed species . Today's target was the Duke of Burgundy and we set of early for deepest Kent . On arrival at the Forestry Commission managed site , the first thing found on the track were several Glow Worm larvae , and Keith found an unusual centi/millipede type specimen that neither of us had seen before . When we arrived at the spot where I had seen this species before , there was no sign , but within a short time , we started to find them a bit further along the slope . A small butterfly , about the size of a Small Copper , resembling a Fritillary , especially the Heath Fritillary , but smaller , and distinguished by it's fast , whirling flight . It's rarity is comparable to the Woods White that we found yesterday . Both sexes are very similar , but of interest , the male uses just four legs , whereas the female uses all six . Some say it is so that they can run faster than the males ! We saw between 10-15 , all males , but failed to find a mating pair like yesterday .
The site also has good numbers of Orchids , including Fly Orchid-Ophrys insectifera , a species found mainly in the South from Kent to Dorset , and also in the Chilterns and Cotswolds .
Another species found was the Lady Orchid-Orchis purpurea , which is found almost entirely in Kent . Also found were Greater Butterfly Orchid , not yet in flower and a few Early Purple Orchids , along with lots of Twayblades . Whilst searching for Butterflies and Orchids , I came across one of the gardener's friends , a Lacewing-Chrysopa septempunctata , who will happily chomp away on aphids . Other Butterflies recorded on the site included , Red Admiral , Speckled Wood , Green Hairstreak , Dingy Skipper , Brimstone , Orange Tip , Large and Green-veined White , Peacock and my first female Holly Blue of the year , identified by the much larger dark markings on the forewings . Several Wood Ant nests were found , and these individuals were dealing with a fly that they found or caught along one of the paths . Birds seen/heard included my first Turtle Dove of the year , Blackcap , Garden Warbler , Common Whitethroat , Willow Warbler , Chiffchaff and 3 Raptors . Moths recorded included Mother Shipton , Speckled Yellow , Double Purple Bar , and two Pyrausta species , purpuralis and nigrata . Eventually , it got so hot that the Duke of Burgundys retired to the shade , and we started back towards home , making a stop at New Hythe , to see if we could find a Water Vole . Entering from the Water Treatment gate , apart from hearing a Nightingale , we found a pair of Soldier Beetles-Cantharis rustica , living up to one of their common names - Bonking Beetles . Near the Diver's Bridge , we spotted a couple of Hairy Dragonflies and an Emerald Damsefly , along with Large Red , Azure and Common Blue Damselflies . The Common Blue can be identified by the 'golf ball on tee' marking , on the first segment behind the thorax , and the last two segments all blue . We walked the side of the ditch up to the scrub area without finding a Water Vole , but serenaded by 2/3 Nightingales as we did so . On the scrub area , we found a probable Dingy Skipper and another specimen of the moth found yesterday at Dorking , which I still think is a Treble Bar . Walking back to the Diver's Bridge through the Hawthorns in full flower on the other side of the ditch , we found 3 Grizzled Skippers amongst the grass . The walk back to the car failed to find a Water Vole , but it was a very pleasant end to the day .
I only saw one of the Raptors earlier , and failed to get a shot of it , but Keith did manage one before it disappeared over the tree line , and would be interested in what readers make of it , especially that long tail .

In answer to a couple of queries raised over last night's post :-
Dean - Yes , I agree that it does look like a 5 Spot , but the spots on a Six Spot are very variable and they often join together . The habitat , chalk grassland dictates 6 Spot , as the 5 Spot is only found in SW England and Wales and is found in damp meadows , marshes and sea cliffs .
ShySongbird - Fear not of confusing Wood White and Real's Wood White , as the second is only found in Ireland . If you do see them in Ireland , apparently the only way of separating them is by close examination of the genitalia ! As for 'hearing' the Wood Ants working on their nest , in the quiet woodland surroundings , we could hear a constant rustling type sound as fresh Pine needles were brought to the site and dragged to the entrance and the constant work going on about the nest added to the sound .

Thursday 20th.May 2010

Having postponed the trip earlier in the week , I decided to chance the weather , and go looking for the rarest White butterfly , the Wood White .I was joined on the trip by Keith , my fellow butterfly enthusiast from High Elms . We set off in beautiful sunshine for woodland the other side of Guildford . Apart from a couple of slow patches on the motorway the trip went well until we approached the A3 , and a large bank of cloud , stretched across in front of us . We pressed on , and arrived at the wood in overcast , but mild conditions , not exactly conducive to butterfly spotting . The weather did not affect the birds in the area , and we were greeted by , Nightingale , Blackcap , Chiffchaff , Garden Warbler , Common Whitethroat and Cuckoo . We headed off along a broad ride , and within 5 minutes we had found our first specimen . A small and delicate butterfly with a slow , fluttering flight . There was hardly a breath of wind along the ride , and more butterflies were found , some feeding on the Greater Stitchwort , and some still at rest . In an open area , we also searched for Pearl-bordered Fritillary , which I had seen many years ago on the site , but did not find any , they probably needed some sun to encourage them out . We found two pairs of Wood Whites courting , facing each other , and flicking their wings , whilst touching antennaes . Then Keith followed a pair across the open space , and within a couple of minutes , they were coupled . We also recorded Orange Tip , Dingy Skippper , Brimstone and Green-veined White . Also found was this Cardinal Beetle-Pyrochroa coccinea . The Nightingales sang all the time we were on the site as did the Cuckoo . Several Wood Ant nests were found , and at one we stood and listened , and we could hear the Ants at work a couple of metres away . By lunch time , with no change in the weather , we decided to try our luck at another of my favourite sites on the Downs , high above Dorking . By the time we arrived , the cloud was thinning a bit , and more importantly , the slope was out of any wind . The most obvious emergence seen on our arrival was that of the 6 Spot Burnet moth , and they were all in pristine condition . A flash of metallic blue was our first sighting of a male Adonis Blue , looking similar to the Common Blue , but having the black lines crossing the outer white fringes of the wings . There weren't large numbers of this species , as the first brood is usually considerably smaller than the second , which will be on the wing mid August to September . Just one female was found and she was in pristine condition too . Other species recorded were Green Hairstreak , Grizzled Skipper , Large White , Small Heath , Peacock and just before leaving a couple of male Common Blues , without the black lines crossing the white outer fringe , bringing the day's tally to a round dozen . Apart from the Burnet moths , Mother Shipton , Burnet Companion and I think Treble Bar , although neither of us managed to get a shot of it , were also seen . Lots of Soldier Beetles were seen , along with this Rose Chafer-Cetonia aurata , and a couple of Leaf Beetles-Cryptocephalus hypochaeridis , I think , who seemed to be enjoying themselves .
A day that seemed doomed on the outward journey , turned into a very successful one , in very good company .

Wednesday 19th.May 2010

I was the only person available to do the Dormouse/Reptile survey up on the Greensand Ridge today , so Carol came along to help with the recording , which was a great help . I use the word Dormouse loosely , as at this time of year , many of the boxes are in fact homes to Tit families . Of the 50 boxes at the first site , 23 were occupied by Blue Tits , with eggs in some , newly hatch youngsters in others , whereas , one of four Great Tit nest found , had young with first feathers coming through . Also found was a single Wren's nest , but no sign of any Marsh Tit nests in their usual area , where springs keep things damp . Another nest found , but not in one of the boxes , was a large stick construction , in the same tree where we disturbed a Common Buzzard when we last did the survey . Whilst there , we could hear the birds calling over the fields beyond the woods , but never sighted any of them . Will have to visit the area again soon . Also in another area , I heard a very strange repeated call that I couldn't identify , but later heard a Tawny Owl calling from the same area , and wondered if the earlier call had been a youngster . Despite all the bird interest in the boxes , the very first box opened had this portly male asleep inside , and , very close to the Common Buzzard's nest , some fresh Hazel leaves in this box , hid these two others , oblivious to anything happening , in their torpid state . They turned out to be a male and a female , both weighing 13 gms. , so this box just might support a family in a short while , if we are lucky . The wetter parts of the site also had large drifts of Ransoms or Wild Garlic-Allium ursinum , in full flower , and with the Dogs Mercury-Mercurialis perennis , the woodland floor was completely carpeted . Still no sign of the Scarlet Elf Cup and I don't think it will show now that the weather is warming up . Two fungi , both of the Polyporus family that were found , were P. squamosus-Dryad's Saddle or Scaly Polypore , specimens of which can grow to up to 60cms. across , and the chestnut coloured P. badius .
The second site of 20 boxes produced 7 Blue Tit nests , 4 Great Tit nests , 1 Wren nest and one Wood Mouse nest without an occupant . Just a single 'overnight' Dormouse nest was found .
I know Reptiles were included in this survey , but , from 35 pairs of refugia turned today , just one juvenile Slow Worm and one large , probable female Grass Snake , was all that was recorded . We felt the heat walking around , and I'm sure the reptiles did too . The corrugated tin squares were hot enough to cook an egg on , so nothing would want to lay under them . As we finished the survey , the cloud rolled in , and the sun wasn't seen again .
