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....

📣 New paper 🎉 Proud to have helped with this nice study by @wlangdon12.bsky.social showing a trade-off between nutritional quality & microclimate of host plants for Small Copper (Lycaena phlaeas). Here in England, they choose warmth over nutrition resjournals.onlinelibrary.wiley.com/doi/10.1111/...

I thought it was just a battered Small Tortoiseshell on a muddy patch… but something wasn’t quite right. Then it clicked—it was far too big! My first-ever Large Tortoiseshell, emerging in the sun after months of Cornish rain. @savebutterflies.bsky.social @marcusrhodes.bsky.social
