New study led by @dariashipilina.bsky.social links resource limitation as a driver of migration in the painted lady butterfly (Vanessa cardui). The authors show how resource cues reshape gene expression across development.

Do you prefer the mountain 🏔️ or the beach 🏖️? The Mazarine blue chose both. Genomics uncover hidden diversity and lead to the description of two new subspecies from isolated montane and coastal populations in Iberia.

Israël zal opnieuw een podium krijgen op Eurosong. Ondanks oorlogsmisdaden, bezetting en genocide.
Wij kondigen een alternatief aan. Wij weigeren een podium te geven aan genocide en oorlogszucht.

In Belgium as well numbers in summer are much lower than in spring. imo they start hibernation quickly after emerging in june while in spring territorial and mating activity makes them more obvious for observers. The figure shows the statistics of our citizen science website waarnemingen.be

Livestock grazing is essential to maintaining grasslands in the mountains of Europe. Extensive cattle grazing has been shown to be the most beneficial but any extensive system is good
Grassland butterflies are declining across Europe, but how do we reverse that trend? We have just produced a report with some simple guidance to land managers and policy makers on how to 'Bend the curve' and help increase butterflies and other pollinators. www.bc-europe.eu/webpage.php?...

lost niets op en kan gemakkelijk tot ICE-achtige toestanden leiden. Zie ook de bijdrage van Romy van Baarsen op Linkedin vandaag en haar opiniestuk in de Volkskrant gisteren.

According to the latest reports, at least 83 children have been killed and 254 wounded since 2 March in Lebanon, as hostilities have intensified. On average, more than 10 children have been killed and approximately 36 children injured every day over the past week. UNICEF urges immediate efforts to de-escalate the situation and prevent further harm to children.
“As military strikes continue across the country, children are being killed and injured at a horrifying rate, families are fleeing their homes in fear, and thousands of children are now sleeping in cold and overcrowded shelters.” - UNICEF's Edouard Beigbeder

An unholy coalition between EPP and extreme right just adopted a law enabling ICE-style structures and deportations. A step closer to a dystopian, Trump-inspired deportation policy.
A big step away from a fair, humane and efficient migration system. I urge the EPP to rethink before the plenary vote.
A boy plays football inside a church property-turned shelter for displaced people in Beirut yesterday. More than half a million people are now displaced by war across Lebanon, according to authorities. Almost 400 have been killed, including 83 children. Report soon, @irishtimes.com

Be our allies, there is so much to fight for in this era of eroding rights #IWD2026
After the extremly hot and dry summer of 2018 numbers of the Dark green fritillary (S aglaja, grote parelmoer) on Dutch Butterfly Monitoring transects crashed and has not recovered. I fear it could get extinct in NL soon, what is amazing for a species that can live in so many different habitats.
The asymmetry of the value placed on human life is so striking. Israel has a goal to recover 40-year-old remains; to do so, it invades a sovereign country, and the lives of 26 Lebanese are an afterthought. Their names not even worth printing in the New York Times.
Only for some 30 aggregates, ranging from 2 to 7 species.
It doesn’t matter whether the rate of global warming is increasing. It’ll never cease to amaze me that people don’t care that it’s happening at all. It should be the most alarming thing ever.
So this arrived today, I don't think that micromoths of the low countries have ever before been compiled in one (2 volume) guide before in such a clear and accessible way, with life cycle info. Anyone with interest in micromoths of NW Europe should buy this! knnvuitgeverij.nl/artikel/hand...

📣 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/...
New paper! Bird nests (Wood Warblers) are hubs of invertebrate biodiversity on forest floor, hosting more species/individuals than leaf litter. Probably due to heat & food detritus. Losing Wood Warblers = ecological networks lost. #ornithology
