Thoughts at the end of my Big Butterfly Count 2026
Three weeks of fun in the sun clearing my mind outdoors by looking for and counting a selection of butterflies and day-flying moths all for a good cause to take the pulse of populations in Butterfly Conservation’s ‘Big Butterfly Count’ draws to a close, I’ve enjoyed it immensely again. I do multiple counts across different parts of my local Lakeside Country Park on working from home lunch time and evening walks as well as some when out at other places on office working days and at weekends and put together a leaderboard of all the species and how many I’ve seen at the end. Below are some observations from my counts this year.
I saw a little less than last year and that is likely down to the heatwave
I saw 538 butterflies in total compared to last year’s 696, seeing on average 17.93 per count compared to last year’s 21.75. I saw 358 butterflies on the counts done at Lakeside this year compared to last year’s 420. Last year I saw 26.25 butterflies on average per count at Lakeside compared to this year’s 19.89. Still pretty healthy numbers of course but it’s interesting thinking of the intense heat and sunny weather that on first thought maybe it would lead to more being about. However when you consider most of my counts were undertaken during the hottest parts of the day being naturally when I was out with butterflies more active in the coolest parts of the day to adapt to the extreme heat it’s little surprise my numbers dipped a little. There were a few times whilst out counting I felt I was seeing less than usual so it’s interesting to see my data does reflect this.
Meadow Brown reclaims my top spot at the expense of Small White
I had a shock last year as Small White was the butterfly I saw most of during my 2025 counts in total and the Lakeside ones when it’s usually the irrepressibly abundant Meadow Brown, but the latter recovered this year as I saw more than last year topping both of my tables. It was a straight swap between first and second with the numbers of Small Whites I saw down but the amount I saw still the second highest of any species this year.
Early on in my counts it looked more of a tight three horse race with decent numbers of Gatekeepers about and it’s interesting when entering my data into a spreadsheet yesterday I noticed that the Gatekeeper numbers really dropped off partway through the count, reflecting what I felt whilst doing the counts and it losing its top stop nationally on the live leaderboard to Small White. I wonder if the heat meant they largely got their business completed early or couldn’t cope in southern England or perhaps their season just naturally ended during the count having started fairly early. Still it maintains it’s constant top three berth for me.
Common Blue my runaway star
I saw so many Common Blues over the past three weeks and they quite emphatically claimed fourth spot on both my leaderboards, I usually see a fair few across my counts but this was a real revelation of it for me this year.
A good count for Holly Blues too
Holly Blue is one of a nice number of butterflies I will say had a good year with their strong start in spring backed up by a subsequent generation/s and I saw increased numbers in this year’s count.
The Painted Lady big year showed
We’re having an amazing year for migratory insects with me particularly paying attention to Painted Lady, Clouded Yellow, Hummingbird Hawk-moth and Jersey Tiger moth numbers. Whilst I didn’t visit any areas of mass emergence or arrival during the count to see it really surge up my leaderboard they were a consistent presence and went from low down on last year’s leaderboards to around midway. A good sample of their general numbers around I feel and it was rewarding to use the count to submit a few more of the many sightings I’ve had this year.
As above for Jersey Tiger moth
As anticipated Jersey Tiger moth also climbed my leaderboards. Frustratingly at times I saw them in recent weeks at times I wasn’t counting like on the way to work or after I’d counted on a walk but as I say a good sample of their general abundance currently.
Getting through the three weeks I wasn’t seeing too many Small Coppers but a flurry of sightings in counts at Lakeside over the past week have ensured this exuberant butterfly finished with a flourish with more seen this year than last.
Too late for Marbled White and Ringlet
Talking of species’ seasons getting earlier and these two which used to be in their peak as the count arrived emerge earlier and earlier in years down south so they were finished locally for me before the count began. I managed to see two of each only by virtue of a couple of cheeky warm-up counts done in July around two weeks prior to the count actually beginning when the website opened for submission of counts at Lakeside. In recent years I seem to vow not to do early counts each year but usually give in, even with that being so I wonder if I’ll see any in July at all in years to come. It’s an interesting sign of warmer spring weather at times speeding up these species’ lifecycles to shift the season a bit.
A poor count for Six-spot Burnets for me
These day-flying moths buzzing around the meadows is usually a key feature of my counts and in good numbers in years gone by but not so this year with none seen. I’ve only seen them on one occasion this year at all, prior to the count last month at Durlston, and none locally. Worryingly for a second consecutive year I saw no Small Tortoiseshells in my counts either.
The photos in this set are all ones I took over the past three weeks of; Small Copper and Painted Lady at Lakeside on Friday, earlier Lakeside photos of Jersey Tiger moth and female Common Blue and a Meadow Brown at Shipton Bellinger in late July where 32 of them seen was the highest of any butterfly seen in any of my counts this year.
