As it’s my ‘local’ butterfly it had to be the swallowtail for the final day of #butterflyweek

A cool day on the @greenwingstours.bsky.social False Apollo tour resulted in an impromptu photography workshop (20 minutes that turned into 2 hours thanks to all of the great guest questions!), with a Small Copper then appearing as things warmed up. A favourite species for the last 50 years!

A day with butterflies is always a good day 🦋☀️

The Hautes Pyrenees are a stunningly beautiful montane area, and home to a magnificent variety of #butterflies, including some fine endemics and near-endemics. We explore both French and Spanish sides of the mountains, at a relaxed pace ideal for photography. (2/2)

Many journals require data and code sharing. Yet code is still rarely shared and datasets are often hard to reuse.

Our new paper introduces the @sortee.bsky.social guidelines for data & code quality control in ecology & evolution, developed by 26 experienced data editors.

Great new paper from Agathe Puissant's PhD in Ecology Letters: predation‐driven adaptive syndromes combining wing shape and colour patterns in Swallowtail Butterflies onlinelibrary.wiley.com/doi/10.1111/...

A female Small Copper butterfly (Lycaena phlaeas) egg-laying on Common Sorrel (Rumex acetosa)

Two eggs of the Small Copper butterfly (Lycaena phlaeas) on Common Sorrel (Rumex acetosa)

Excited to see one of my PhD chapters now published! We found a trade-off between the quality of host plants and how warm they were for a declining grassland butterfly (Small Copper, Lycaena phlaeas) and looked at how this shaped their egg-laying choices: doi.org/10.1111/een....

I don't know, maybe it's because I'm a big Carl Sagan fan but I'm super dismayed out how many people these days seem to think that Nuclear Weapons are fine. And not, you know, a completely insane way for us all to live.
