For my final day working for @savebutterflies.bsky.social, plus I've not posted an image for while - Watsonalla uncinula (Spiny Hook-tip), ~12mm and I believe in it's 3rd instar (happy to be corrected). Bred ex ova from wild-caught, Oxfordshire female - not by me I should add. #MothsMatter

Butterfly fact 4. Caterpillars consume 27,000 times their body weight in their brief lives. And then they face an onslaught of predators and parasites. But they can fight back! To understand a butterfly, you need to know its caterpillar. Read all about them in ‘Butterflies' from Bloomsbury

Out today: my final paper from my postdoc at the @universityofhull.bsky.social, in which we explored the UK public's views on brownfield sites and biodiversity! So very excited to finally be publishing this paper - a labour of love.

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

Right, the numbers are in. What did my moth trap catch in 2024, and how does it compare with previous years, especially as many moth-ers seemed to be reporting low numbers this year? I mainly trap at two sites (my London flat and in-laws place in Devon), so will focus on those. #TeamMoth 1/4

I love the crazy names given to moths. A favourite is the day-flying moth Mother Shipton. Named after an infamous Yorkshire witch, if you look hard enough at the wing pattern you can make out the profile of an ugly old face. I found this one in the Yorkshire Wolds.

The African Map Butterfly is very unique, being the only member of its subfamily in Africa. It is also super cool and breathtakingly beautiful!

Couldn’t agree more 💥 It also goes both ways — a welcoming attitude from natural history experts towards having data merged in new ways ought to go hand in hand with big data scientists having a firm natural history-based understanding of data, welcoming involvement by species experts
So true. It doesn't mean being an expert in natural history, but at least having interest and curiosity (more goes a long way). I had a collaborator once who didn't have any interest in the study organisms...let's just say it didn't work out.
Quote: "It is very hard to interpret big data in ecology in meaningful ways if you do not know anything about who the organisms are and what they do in the environment."

I may have given a squeal of delight when this beautiful #moth came to the UV light last night. Found in the south west of Western Australia, this moth has pale brown forewings with very distinctive dark brown markings

Dear blueskyers, can anyone following the #qgis #arcview #esri #gis tags help by suggesting a way to put a georeferenced raster with predicted habitat for rare #butterflies online so that it can be used for positioning?

New butterflies in NL: Mallow Skipper (C alceae, kaasjeskruiddikkopje). Short-time populations in the past, but only well established since 2009. First in SE, but now fastest expansion in SW. Can be easier to find as caterpillar than as inconspicuous adult.

The very earliest butterflies flew with dinosaurs and evolved around 100 million years ago as an offshoot of the Lepidoptera (meaning 'scale wings'). Their DNA history has been revealed in a truly remarkable paper by Akito Kawahara www.pnas.org/doi/10.1073/... (2/2)
