Looking back at 2018 part 3 – Late Summer into Autumn.
By the middle of August things were getting back to more normal conditions for the time of year around here, that is a mix of sunny spells and cloudier days with some longer periods of rain at last which helped to revive the parched vegetation hereabouts.
Second brood Common Blues, Small Copper and Small Heath continued to fly around my local spots but Gatekeepers had already disappeared as had Meadow Browns which usually hang on a little longer here, albeit nowhere near as long as they do down south. Holly Blues were still about but not that many and most were looking past their best now.
Speckled Woods were continuing to grow in numbers and on one particular day(19th August) I managed to identify - by comparing photos - 7 different males and 2 females in my garden.
At the end of August and into the first week of September we went down to Dorset for one of our regular late summer visits, staying for a week at Durdle Door next to Lulworth Cove. I have said it before, and will say it again, that I believe this area to be amongst the best in the country for butterflies at that time of year. I must admit I was wondering what I would find following the hot, dry summer, and indeed the sites that I visited were all looking very brown and dry compared to visits in previous years. The weather during the week that we were there was a bit cooler and cloudier than it had been but still quite warm and we saw no rain until the last day.
As it turned out, there were plenty of most of the usual subjects to be seen, I say most because although I saw 19 species down there including good numbers of my main target for the week (Adonis Blues), there were some species that only showed up in low numbers, most notably the usual migrants. During the week I only saw 3 each of Red Admiral, Painted Lady and Clouded Yellow plus by a co-incidence of numbers also 3 Hummingbird Hawk Moths. These, along with lower than usual numbers of Large Whites showed that there was not much coming in from across the channel at that particular time. Small Tortoiseshells and Peacocks were also notable by their absence, a far cry from a few years ago down here when it seemed that every buddleia was covered with them.
Apart from the Adonis Blues already mentioned there were good numbers of Common Blues, Brown Argus, Small Copper and Small Heath to be found at most of the sites I visited. A few Chalk Hill Blues were still hanging on at Bindon Hill above Lulworth Cove, this being the only time I saw this species in 2018. Graylings were still flying at Durdle Door although Meadow Browns were definitely down in number from what I usually see in this area at this time of year.
A late second brood Small Blue surprised me at Durlston Country Park as I had never seen one of these down here at that time of year.
Less of a surprise was a late Marbled White seen at Durdle Door as I have seen occasional examples of these down here in the first few days of September before and they certainly seem to last longer on this stretch of coast than at most other locations.
Back home though the rest of September things were falling into that familiar pattern of decent warm and sunny days through the week when I was at work and then cloud or rain at the weekend. Looking back at my notes, the last two Saturdays in the month were particularly wet and both were followed by dull and gloomy Sundays.
Going into early October, Speckled Wood were still hanging on although most were now looking tired and faded. I saw reports of third brood Common Blues appearing at a few places around the midlands which is unusual for around here so I went out for a look around to see if I could find any. The conditions were far from ideal on the Saturday (Oct. 7th) that I went out with a cold wind blowing and I found just one butterfly which was indeed a single male third brood Common Blue.
This actually turned out to be my last time out looking for butterflies in 2018 as things had just fizzled out locally plus I had used up all my floating holidays from work by now and also needed to catch up on some household jobs at the weekends. This was a shame really as I had seen reports of Clouded Yellows in unusually good numbers for the midlands (20+ including a number of helice) at Sywell Country Park in Northamptonshire which were believed to be the offspring of earlier migrants. Oh well, although I missed them myself, I did see some great photos of these posted by others on the usual social media. There had also been reports of Clouded Yellows sticking around a couple of sites in Warwickshire and Shropshire earlier in the summer so it appears that this species was seen a bit more often than usual in the midlands this year, unfortunately not by myself though... wrong place and time for me as usual.
My very last butterfly of 2018 was a tired Speckled Wood seen in my garden on October 20th.
In the end it turned into a year which reminded me a bit of the weather that we used to have when I was a teenager growing up in the 1970s. That is, a proper winter followed by a changeable spring and then a hot dry summer. There was much talk of the summer being like that of 1976 but, at least around here, the really hot weather ended well before the drought became anywhere near as bad as in that year. That is not to say that it didn't become very dry and parched here which it certainly did and this seemed to adversely effected the summer grassland species in particular. As in most years there appeared to be losers (most Satyrids) as well as winners (Most Lycaenids) and it remains to be seen how the conditions this year have impacted on the numbers for 2019.
All in all I saw 38 species in 2018 which is the lowest final tally I have had for some years now. This was partially to do with decisions that I made before the season started on where and when to have our breaks/holidays around the country and also partially due to the fact that I have decided to try and cut down the miles that I clock up each year looking for butterflies. With this in mind I made a conscious decision to miss certain species this year, especially some of those that are a fair distance from me and I have seen many times before, and try and limit the longer distance journeys to those where we stayed for a few days and could make best use of our time in the area. This is all part of me trying to be a 'responsible butterfly enthusiast' and doing my bit to reduce my own carbon footprint.
With a couple of months of winter still to go I will be thinking of what I would like to see in 2019 and making plans for the forthcoming season, I already have some thoughts in my head so now need to check up on flight periods and look into possible locations and accommodation.
Here's hoping that everyone had a great New Year and is looking forward to a fantastic butterfly filled season ahead.
Neil.
