Reasonable numbers for late season

9/9/2024

Saturday, 7th September, was forecast to have the driest warm weather of the week, especially when compared to the heavy rain and gloomy conditions of the preceding days. It was therefore chosen for transect 23 and proved to be mildly warm and overcast with a couple of brief but light drizzly showers.

Fortunately the butterflies didn't seem to be too unhappy and were seen in reasonable numbers considering the less than perfect conditions and the lateness of the season. There were some gaps in this week's cast list, namely the Purple Hairstreaks, Brown Hairstreaks, Small Heaths and Brimstones, but the Meadow Browns, Brown Argus and Common Blues continue to be fairly well represented. There was a Small White and one worn-looking female Chalkhill Blue remaining.

The number of butterflies seen at this time of year is entirely dependent upon having favourable weather so that they are warm enough to fly, and the availability of their food flowers – without these they will soon succumb.

Timely weather

31/8/2024

GH, GK and BG chose Friday, 30th August, for transect 22. The weather was fine, warm with only a light NE wind: just right for seeing late-season butterflies. We were relieved that the numbers counted had recovered following last week's cold weather plummet.

The Meadow Browns, Brown Argus, Common Blues and Small Heaths were still quite numerous and our Chalkhill Blues were just about holding on. Hill Wood Field's Purple Hairstreaks, which we've seen over the 5 weeks, seem to have finished but we had a single Brown Hairstreak pose nicely for us, only to disappear as soon we tried to get a photo. We also had our first sighting this year of a Green-veined White, in Stagbury Field. Speckled Woods have been seen singly this season but on transect 22 we recorded four.

First Brown Hairstreaks of the season

28/8/2024

GH and BG walked transect 21 (only 5 more to the season's end) on Sunday afternoon in a mix of warm sun and cloud, with a gusting SW wind. This followed on from the previous day's long stretch of rain, which would have greatly reduced the number of butterflies seen on the transect. So that where we saw, for example, 290 Meadow Browns and 41 Common Blues last week, on Sunday these species were down to 64 MBs and 4 CBs. The Chalkhill Blues were still around on Stagbury Field. The highlight of the day was the season's first sighting of 2 Brown Hairstreaks flying around Hill Wood Field's oak trees, where we also saw 2 Purple Hairstreaks.

Meadow Browns still high

20/8/2024

Saturday (17th) was another transect walked in perfect warm and calm butterfly weather. Although the summer is nearing its close the butterfly numbers are holding up pretty well, helped largely by the unusually high Meadow Brown figures for this point in the season (they've normally already begun their decline by week 20). Gatekeeper numbers have dipped suddenly this week to 18 from last week's 102, Brimstones are down from 16 to 3, and the Skippers seem to have finished. On the plus side, 18 long-awaited Chalkhill Blues were seen on Stagbury Field, 41 second-brood Common Blues were counted on several of our sections, and the Brown Argus (second brood) count increased from 2 last week to 13 on this transect. For the fourth week flitty Purple Hairstreaks were still flying around the oak trees on Hill Wood Field.

Numbers still high

12/8/2024

This week's transect was walked on Friday morning in fine, warm weather that was perfect for maintaining butterfly numbers: rain, strong winds or cold at this time of the year could bring about an early close to the butterflies' flight season.

In Friday's favourable conditions, the Meadow Browns and Gatekeepers once again provided three-figure numbers to boost our count total, and we also had a slight rise in the second-brood Brimstones, Common Blues and Brown Argus. The Small/Essex Skipper, Marbled White and Small Heath numbers are now in decline, while Silver-washed Fritillaries and Purple Hairstreaks are holding steady. This week was the final week of the normal high point for sighting Chalkhill Blues and, at last, we found them, but sadly only four – two on Stagbury Field's Horseshoe Vetch patch and a single on each of Hither and Coneyboro Fields.

Record number of Meadow Browns

4/8/2024

We chose the morning of Friday 3rd August for transect 18 as it was forecast to be cooler than the previous sweltering days. It followed the heavy downpour and thunderstorm of the evening before and, as we started our walk, the early mist was starting to thin. Fortunately, it was warm enough for butterflies to be flying. As the sun slowly broke through the cloud the warmth increased, so that eventually it was hot and humid, but the butterflies seemed to like it. This was one of the rare occasions that we saw butterflies (in this case Meadow Browns and Gatekeepers) in all 12 transect sections: we counted 363 MBs (our highest ever) and 130 GKs. We also saw second-broods of Brown Argus, Common Blue, Brimstone and Red Admiral. The Purple Hairstreaks were flying around Hill Wood Field's oak trees – just as difficult to spot as last week but fortunately sociable enough to pose for photographs. According to BCT's records the peak of the Chalkhill Blues' flight period is between 22nd July and 12th August each year but, with little more than a week remaining of this period, we are still waiting for our first sighting.

Ideal for butterflies

28/7/2024

GH, GK LN and BG walked transect 17 (of 26) in the morning of Friday 26th. The weather was warm with occasional sunny spells to help maintain the temperature. It was ideal for butterflies, who were seen in high numbers across most of our 12 sections. As per last week we followed the revised route, entering Fames Rough from the downhill path beside Coneyboro Hill Field and crossing Coneyboro on our return.

Once again the most prominent in our count were Meadow Browns, Gatekeepers, Marbled Whites and Small/Essex Skippers. Over the last couple of transects we have craned our necks looking high into the oak trees along the top of Hill Wood Field for Purple Hairstreaks and on Friday afternoon there they were – difficult to spot at first but after a few patient minutes we saw them flittering high in the branches and then coming down, giving us close-up views for our cameras. We're still awaiting our first Chalkhill Blues on Stagbury Field's Horseshoe Vetch patch, their emergence due about now. We also had our first Silver-washed Fritillary and a Painted Lady, plus possible second-brood Brimstones and one each of a Common Blue, and a Small Copper. Our total count for this transect was 495, our second highest of this season, from 16 species.

Still active in mixed weather

22/7/2024

Saturday the 20th was our choice for this week's butterfly count. The high temperatures of the previous few days had lessened and Saturday was cloudy, breezy, and very humid as we started out and we soon encountered a brief shower of rain in section 2 (Coneyboro Hill). This transect was our first using a revised route that bypasses the dreaded steep downhill path into Fames Rough and removes the non-productive walk through Harholt Plantation (sections 5 and 6). From Fames Rough and beyond the weather was warm enough to tempt out a reasonable number of butterflies across the remaining sections, so in all it was a fairly successful count covering all of our high-summer butterfly regulars.

Count Details:
143 Meadow Brown
108 Marbled White

High season

14/7/2024

The week's changeable weather made it difficult to select the best day for our transect but we made the right choice for Thursday (11th), when we had excellent conditions both for transect walkers and the butterflies.

We're now into the high season for butterfly activity and this week's count of 561 from 11 species was this year's highest to date. The figure was largely due to the mass numbers of Meadow Browns, Marbled Whites and Small/Essex Skippers seen across almost all of our transect's 12 sections. We also recorded the season's first Gatekeepers whose numbers should increase rapidly over the next two or three weeks. This week's butterflies were all from species that make up the majority of our transect records and the only 'exotics' we saw were three off-transect probable Dark Green Fritillaries. Others are expected any time now – these include the Chalkhill Blues that will emerge from the Horseshoe Vetch patch on Stagbury Field and the Purple Hairstreaks that will be flying along the line of oaks along the upper slope of Hill Wood Field.

248 Meadow Brown

GK, LN and BG walked Transect 14 on Friday afternoon - the weather was warm, with sun and an occasional cloud and cool breeze.

The total count was 401, 10 less than last week's figure, and comprised virtually the same species with the addition of a photogenic Comma on Coneyboro Hill and our first Speckled Wood of the year.
