Hehe but that light module in the mug is bespoke 😃🦋

Here's London: log-transformed abundance on the left, richness on the right. Previous years in red, 2024 in black. Trend lines fitted using GAM (all years and just 2024). Take home message: 2024 was normal for London. Or, every year is a bad year in the Borough of Camden. #TeamMoth 2/4

...London is constant effort in 1x20W actinic. Number of traps in Devon varies depending on opportunity, and has increased on average over the years. I was running 3 on some nights this autumn. So London more reliable indicator, but catches always low there. Make of that what you will! #TeamMoth 4/4

And here's Devon: log-transformed abundance on the left, richness on the right. Previous years in green, 2024 in black. Trend lines fitted using GAM (all years and just 2024). Take home message: fewer trap nights, but looks fairly typical. Except for a good few days in autumn, but... #TeamMoth 2/4

Not sure about the pre-July 2012 population in Finland. In Sweden, volunteers discovered and reported the butterflies coming across the Baltic sea, reaching Gotland in the SE

This is the colonization process in Sweden, starting July 2012 (followed by 95% leaving in 2014-2015)

The invasion actually happened in July 2012, then the Scarce Tortoiseshell population stayed a couple of years before moving on so for Sweden, that map mixes the pre-2012 population with those that established during the invasion

Thanks, that sounds promising! I was thinking CartoDB first but haven’t seen them using rasters and now the free option seems gone too

I was thinking of putting it online so that you could use positioning through your phone browser and locate yourself on the raster
