Peter Taylor (1926-2011)

Another passing …

My good friend Peter Taylor, who was perhaps the longest serving member of the Amateur Entomologists’ Society (he joined the AES in 1946), died peacefully in his sleep at his home in Kirdford, West Sussex on 20th October 2011, he was 85.

Peter was born in Luton, Bedfordshire. On leaving school, he undertook a five-year apprenticeship as a mechanist and turner in the toolroom of Commer Cars, Luton, taking evening classes to gain a National Certificate in Mechanical Engineering. His spare time was spent plant and butterfly hunting on the Bedfordshire downs and elsewhere as an active member of the AES and of the Botanical Society of the British Isles (BSBI). His knowledge of the British flora was encyclopaedic, a rarity nowadays amongst Kew botanists. He made a considerable and beautifully prepared herbarium of British Plants, now at Kew, as well as a fine collection of butterflies from his extensive breeding programmes.

Peter joined Kew, starting as a Temporary Assistant in the Herbarium in 1948. His eye for a plant, craftsmanship and attention to detail made him a stalwart of the Tropical African Section. As an Experimental Officer Peter Taylor was delegated to largely curatorial and technical duties and soon gained a remarkable knowledge, particularly of the herbaceous plants of the region. In late 1955 he married Shirley Patten, a scientific assistant in the Kew Herbarium. Shortly afterwards, he undertook an eleven-month expedition to East Africa with Edgar Milne-Redhead, spending six months during the rainy season in the Songea District of Tanganyika (now Tanzania). They worked very long hours, carefully arranging plants in presses late into the night and up again at dawn mostly seven days a week.

It was not until Sir George Taylor left Kew that he was given long-overdue promotion to Principal Scientific Officer in 1972. George’s nose had been put out, so it was said, because he kept being congratulated on Peter’s work on Utricularia. Unfortunately he had been passed over to head the Fern Section and was assigned the Orchids, which he ran from 1972 until 1984. He published a popular book and many articles on orchids. He discharged his duties conscientiously but was glad when younger members of the section could take over this specialist group and he could devote more time to the Utricularia. He made visits to Australia and America and examined vast numbers of specimens with visits and loans. He was awarded the Kew Medal in 1990 for his services to the Royal Botanic Gardens. He continued several years after his retirement in 1986 to hone his outstanding monographic revision of the genus, each of the 214 species illustrated with his own fine drawings. The appearance of his definitive monograph of Utricularia coincided with his retirement from Kew in 1986.

Peter fitted well into the tradition of great British naturalists. He was a fine entomologist and had an encyclopaedic knowledge of British Lepidoptera and other groups. He was a great friend of the respected entomologist Peter Cribb and a regular companion on bug-hunting trips from 1956 onwards. They enjoyed each other’s company and shared a wacky sense of humour.

In retirement he settled in the West Sussex Weald where he purchased two woods that he restored to good condition through coppicing and cutting rides. In the course of the restoration, he made several new insect and plant records for the Vice-county. He was particularly pleased that the Purple Emperor (Apatura iris) bred in one of his woods thanks to his careful management of it. Peter was an outstandingly good cabinetmaker and specialised in making harpsichords and clavichords to the most exacting standards of craftsmanship. His instruments have graced concert platforms, played by Margaret Hunt, the wife of his former colleague and old friend David Hunt.

He will be sadly missed ...

A lighter note …

On Wednesday, 16 November I was contacted, in my professional capacity, to investigate and help resolve a seasonal problem with flies in a local Sussex windmill. The mill, which I won’t name for reasons of client confidentiality, has suffered problems for a number of years particularly during the autumn and winter months.

Thaumatomyia notata which is commonly known as the Yellow Swarming Fly, is a small yellow Chloropid with black markings which breeds in very large numbers in the roots of grass, where its larvae are predatory on root aphids. T. notata is generally believed to overwinter as a pupa though a certain number of this generation emerge before the onset of cold weather. During favourable summers and warm autumns the adults may emerge in very large numbers prior to seeking shelter as soon as the nights become cooler. Most of these adults will not survive hibernation.

It is not unusual for vast numbers to occur in buildings where their presence can become a serious nuisance. Though there is generally little that can be done to prevent such problems the application of topical insecticides provides symptomatic relief when problems are experienced.

Heyshott Escarpment, 23 November 2011

Cardiovascular conservation …

Today, along with Colin Knight and Neil Hulme and five members of the Murray Downland Trust, I continued my weekly work party season at Heyshott Escarpment. After a foggy start the sun burnt through leaving a very pleasant autumn day. It was difficult to think of a better place to be …

This is an extremely exciting project and one where positive management and hard work is continuing to improve the habitat for the Duke of Burgundy whose population appears to be doubling each year. The continued aim of the work, which has been ongoing for several years, is to create conservation corridors whereby linking strategically located habitats for the Duke of Burgundy, namely the exposed chalk workings higher up the reserve, down into the lower wooded areas below.

Roll on next week …

26 November 2011

I have recently been scanning through historic distribution records for a number of Sussex butterflies and comparing the information with current literature. My main points of reference have been the data published by the Biological Records Centre in 1970, in the form of their Provisional Atlas of the Insects of the British Isles (Part 1) Lepidoptera Rhopalocera which includes the records received from 620 recorders up to and including 31st December 1969 and The British Butterflies (Their Origin and Establishment) by R L H Dennis (1977).

In some species, a data set showing an increase in population as of the current date, may of course imply increased recording due to renewed interest in the species or under recording at the time of earlier data collection and vice versa. A genuine population increase or decrease may of course also be occurring. I am no statistician so have no intention of delving deep into any of the figures I have read though I do find the demographic trends and requirements of different species most interesting.

To take just one example in my own county of Sussex, the Silver-spotted Skipper (Hesperia comma), it is interesting to note the trends in populations recorded. H. comma was recorded in 53 tetrads throughout the county in 2009. During 2010 the butterfly was recorded is fewer tetrads though this is probably a reflection of a reduction in recording capacity as opposed to any change in the distribution of H. comma. Comparing the distribution map from 1970, to that produced in The Millenium Atlas of Butterflies in Britain and Ireland (2001) it would appear that although the species is undoubtedly a rare butterfly with numbers plummeting during the 1960s and 70s, it started to increase its range during the 1980s and 90s and continues to do so slowly with seasonal highs and lows. H. comma is a highly colonial species which is confined to the calcareous and more desiccated landscapes of Southern England. 2011 was the first year that I actively looked for and found this beautiful little insect in Sussex.

Heyshott Escarpment, 30 November 2011

Extra help …

The small party of regular conservation volunteers continue to make excellent progress at Heyshott and have almost broken the back of clearing the current work area of scrub. In order to provide a variety of future grazing pressures, rotational mixed grazing (cattle and sheep) will be implemented during 2012. The installation of stock fencing is due to commence shortly.

Today, our regular work party members were joined by my son James and his friend Billy. After an apprehensive start and continued hard work throughout the session they both came away having enjoyed what they had both achieved - or at least that's what they told me … and they thought they were getting a day of school because of industrial action!

Whilst the fires continue to burn the prospect of what will follow leaves us all excited with anticipation for the coming season …

Burpham, 4 December 2011

One for the pot or a bird in the bush …

With several hours to spare late morning I decided to head over to The Burgh and adjoining area to the northeast of Arundel in West Sussex, in search of the juvenile Rough-legged Buzzard (Buteo lagopus) which has recently and frequently been seen in the area. Checking the SOS website put me on the spot where others had seen the bird previously, in the valley that runs northeast of Burpham village - a known raptor hotspot!

Parking at the triangle located along Peppering Lane, I checked out the surrounding fields for movement. A number of Common Buzzard were in the area and a Kestrel was seen hovering nearby. Recent reports have mentioned sightings of the bird sitting on top of various game feed stations which are quite numerous and located around the field margins. I decided to check these out and was rewarded with a large buzzard-like bird sitting on a distant feeder.

I watched the bird preening and looking around for probably 10-15 minutes before it finally lifted from its perch. It was only then, when it took to the air, that I was able to see its distinctive white tail with a broad dark band at the tip. I watched the bird for about an hour in total and witnessed it hovering above the fields, though never moving far from where I’d first located it.

As I walked back towards the car I couldn’t help but notice a series of rabbit cage traps situated in the distance along the edge of a field with their forlorn looking occupants awaiting their fate!

A picture of the RLB was never going to happen …

Alright Mark? I was really glad to see you offering extracurricular activities for your son and his friend on the Strike day! :D Even if it does nothing for teachers pensions at least the strike action had provided benefit for the local wildlife.

Rough Legged Buzzards are on my hit-list so I read with envy about your sighting, still I'll be checking the Birdnews a bit more frequently now that it's actually starting to feel like "winter", so who knows?

Keep them working I say ... :D

I know it's a bit of a hike for you but the Rough-legged Buzzard seems to be staying put in the valley where it's been for some time. I'm only really free during the week at the moment but if you get a day off and have 'permission to go on a jolly' I'd happily show you around.

Good hunting.

Kind regards. Mark

Cheers for your kind offer Mark :D but permission has been denied as we're booked solid for the next couple of weeks becasue of Christmas :( . I don't think I'll be able to manage to get out much before the "big one" on New years Day. Oh well I can add it to my list of "missed this year" along with Snow Bunting, Shore Lark, Lapland Bunting and Twite - all species that have been down at Cristchurch Harbour that I haven't gotten to see.

Favourites from 2011 - Part 1

It is very hard to believe that I only purchased my camera, a Panasonic Lumix DMC-FZ45, back in late June … the large number of digital images I have accumulated would suggest I’ve had it considerably longer! Though I usually try to separate the ‘wheat from the chaff’ on a regular basis I’ve recently been having a good sort out.

The following images bring back some very fond memories.

I’ll post my favourite shot of 2011 at the end …

Favourites from 2011 - Part 5

And finally to my favourite ...

From my diary of 5 September 2011

I arrived at Kithurst Hill some fifteen minutes later. The ground was wet and it was still windy but its main flower meadow faces north and is generally fairly protected by its wooded perimeter. This is one of my favourite sites on the South Downs and has been very productive in the past. I entered the gate to the meadow and walked west. Almost immediately I came across a stoat quartering the fields in hot pursuit of a rabbit. The chase over and the stoat left hungry it came running back through the wet meadow, stopping every now and again to stand up on its hind legs and smell the air and then move on ...

... Before leaving Kithurst Hill I decided to try to get a photograph of the stoat I had seen hunting earlier. I sat down in what seemed like a suitable spot, camera at the ready and started calling. Within just a few seconds the stoat, now with evidence of a kill around its lips, appeared once again from within the thick bush it had disappeared into earlier, its den probably within. I managed four very quick shots of this fabulous small mammal before it vanished once again. At one point it came within two metres of me.


I'll admit luck played a big part ...
