A total of 385 bee species!! The incredible work carried out by @curromolina.bsky.social et al. demonstrates the great biodiversity of hymenoptera found at the Doñana protected area. My congratulations to the authors. Beautyful piece of work.

Estados Unidos puede tener ciudades llenas de tiendas de campaña, gente arruinada por una enfermedad o familias trabajando para seguir siendo pobres, que el problema es el comunismo. Por eso hacen falta otros 350.000 millones para el ejército. Menuda distopía

No entiendo en qué momento hemos dejado que el más inútil sea el que gobierne. Siento decirlo, pero sí: todos los políticos son iguales, como mucho algunos dan más asco que otros. Y eso será siempre así hasta que ser político sea un trabajo más, igual de remunerado que cualquier otro.

Against the long-lasting dismissal of evolutionary significance of subindividual variation in plants, we show in this preprint that intraplant epigenetic mosaicism of somatic tissue (leaves) predicts the epigenetic and phenotypic divergence of pollen within the plant www.biorxiv.org/content/10.6...

The bands of 'Nycteola siculana' are similar in colour to the schists in that area and to the ‘dirty’ colour of melting snow at that time of year. Lovely!

Among Andrinade, 'Andrena solenopalpa' has exceptionally long mouthparts. This picture of a male shows that the extendable portion measures more than half the length of the body. Pollen grains in the galea suggests that this adaptation promotes pollination. funding: @britishecologicalsociety.org

Asumo mi ignorancia en estos dos generos, pero a simple vista Melecta me parece como más "despeiná" mientras que Thyreus tiene los pelos tan cortos y organizaditos que parecen pintados. Además creo que Thyreus es más tardía. Coincido contigo.

‘Bombylius cf. analis’ on 'Lithora fruticosa'. If I'm not wrong, this species features a sparse hair with a tuft of black hairs on the side of the abdomen, an evident white abdominal line, and a dark area on the leading edge of the wing fading into cell r1. Funding: @britishecologicalsociety.org

Javier Valverde @j-valverde.bsky.social · 19/04/2026
At least that is what this sequence suggests. This flowers after being visited showed the corolla 'sliced'. I'll check other flowers these days. This is a common visitor these days in one of the opulations I'm surveying.

The end justifies the means. Not long enough mouth parts? No problem you can always cut the corolla. 'Andrena' species (help is appreciated) on 'Lithodora fruticosa'. Funding: @britishecologicalsociety.org

In this study led by Carlos Herrera @cmhmaliani.bsky.social, we describe three new species of Andrena. The intensive survey over 27 years at the Cazorla range demonstrates the importance of this genus in the pollination of the flowering plant species in this area. 👉 jhr.pensoft.net/article/1659...
Plot on the left depicts the frequency distributions of Andrena species visiting the flowers of individual plant species showing that, in most of plant species pollinated by Andrena, the number of Andrena species is low. The plot on the right shows the phylogenetic relationships of the 292 plant species surveyed in the Cazorla range and associated number of Andrena pollinators, this picture highlights that flowers of ca. 56% of flowering plant species in Cazorla are visited by Andrena species.

Springer Nature journals failed to assign references correctly in many articles, incorrectly linking to the first article of the volume, thus misleading citation statis. Researchers pay up to €10,000 to publish in these journals, often public money. Reviewers do not charge arxiv.org/pdf/2511.01675

The decline of taxonomists is truly worrying. Perhaps, the capitalist vortex created by impact factors and publishing mafias, with the support of institutions to finance projects that comply with their standards, has something to do with it. It's just an opinion...
