It really wasn't done with any rigorous scientific method involved, Rob. There were a lot of approximations in among those numbers, especially at the height of the season and on days when I set out to count one or two particular species. When numbers were low the totals would have been more accurate.robpartridge wrote: ↑Sat Mar 09, 2024 11:06 am Crikey... Rather puts my record-keeping into the shade!
One thing I can add to the lists above is another detailing the highest counts in one day of each individual species.
1. Meadow Brown 250+ (all my attempts to make an accurate count of this species failed dismally!)
2. Red Admiral 153 (This, on the other hand, was pretty accurate...

3. Peacock 113 (also accurate)
4. Gatekeeper 100+ (another approximation)
5. Holly Blue 52 (possibly my highest ever one day figure for what is always a frequently encountered butterfly)
6. Essex Skipper/Small Skipper 50 (the individual peaks for these two did not coincide, but the difficulties in differentiating between them made it hard to list them separately. This total of 50 came twice - once with SS well underway and ES just starting (rough split 25-25), and then again at peak ES time (ES 40 - SS 10))
7. Small White 35
8. Brown Argus 34
9. GVW 30
10. Comma 29
11 Common Blue 27
12. Orange Tip 23
13. Large White 21
13. Small Heath 21
15. Speckled Wood 20
16. Brimstone 18
Everything else had maximum counts in single figures.
