Postcard from the field from our Summer Orchids of the French Alps tour today: We spent much of the day at over 2,600masl, with some lovely, characteristic orchids of that elevation to enjoy. Frog Orchid were commonplace, while Alpine Marsh Orchid were scarcer, but also much enjoyed.

It's only taken 35 years of visiting the French Alps and Pyrenees to finally get settled views of a Peak White. A late highlight yesterday afternoon here in the Alps, all my previous sightings of this (in)famously mobile species have been butterflies zipping past at great speed.

If you like it you shoulda put a ringlet on it... We're home after our successful first Butterflies of the Hohe Tauern - Austria's Mountain Heartland tour. Over 90 species recorded, 15 of those being Erebia ringlets. The 2027 edition is long ago fully booked. 2028 dates to follow... #butterflies

A fair personal shift put in today - 16 kilometres walked, almost 1,000 metres of cumulative elevation gain. And here are the two personal highlights - self-found Silky Ringlet and, most thrillingly, Swiss Brassy Ringlet. Delighted to share both with our @mariposanature.bsky.social guests.

A truly outstanding day of butterflying in Austria, with a cable car up to 2,200 metres above sea level, into the homeland of the achingly rare Austrian endemic White Speck Ringlet. Many seen with our @mariposanature.bsky.social guests, and a great many other desirable ringlets besides.

For years I studied limpets, and they quietly invaded every corner of how I think. Evolution, cognition, human prehistory, climate science… it all starts with a small mollusc on a rock. The first episode of my series « A Natural History of Limpets » is about why nature keep producing limpets !

A Natural History of Limpets, Part 1: Limpetization

In which we define the subject, and where carcinized crustaceans are humiliated.
