My Progress So Far
I've done it! I've seen a different butterfly species in each of London's 33 boroughs this summer (2021). I visited over 60 amazing green spaces across the capital (more blogs to come) and saw 38 species in total - 5 species (Chalk Hill Blue, Grizzled Skipper, Dark Green Fritillary, Small Blue and Silver-washed Fritillary) were seen but didn't make the final 33 as they were seen in boroughs that were already ticked off.
