En el mundo hay más de 21,000 especies de abejas, con diferentes formas, colores y tamaños. Aquí hay una muestra de lo que hay en México, país con la segunda diversidad mundial. Si quieren saber más les comparto este pequeño artículo que hice: inecol.mx/index.php/divu…

Three new species of the rare cleptoparasitic #bee genus Austrostelis are described, extending its range into Mesoamerica. A new species from Venezuela sheds light on its diversity in northern South America. Read paper here: doi.org/10.17161/jom.v…

My lab is keen on recruiting grad students for 2025 (fully funded positions! Living wage!) on topics related to plant phylogenomics, macroevolution, and adaptation to dry environments: See: edelinegagnon.wixsite.com/gagnon-lab-1..… Job Details: docs.google.com/document/d/1...

A little busman's holiday of mine is collecting bees of the Caribbean. 3 trips to St. Croix last year. This year 3 trips to St. Thomas. This is Centris smithii a species that was here-to-fore unrecorded for the island. One of 3 Centris that were newly located.

Bee gynandromorphs, individuals with both male & female traits, have been documented across several genera & families. Now, a bilateral gynandromorph is reported for Hoplitis for the first time! 🐝 Read more: doi.org/10.17161/jom.v… #Entomology #Bees

Unfortunately only managed to get a male, but during my time in UT this summer I managed to collect a cool Melissodes sp! This is M. exilis isn’t that interesting of a species. Morphologically, the males are cool because they have a mostly black clypeus. Similar to microstictus.

No words.

The gene sequence of the parasite Apanteles piceotrichosus is reported for the first time, along with new distribution and biology data: doi.org/10.3897/jhr.98… Texas A&M University Colegio de Postgraduados #biocontrol #parasitoids #Hymenoptera

The phylogeny of anostomid fishes has just been published with 204 specimens of 97 species and all the 17 genera. We redefine the three subfamilies and describe the new genus Brevidens. Huge 15-year effort now available - open access in @Neotropi : scielo.br/j/ni/a/YxcfHnk…

Bees are finally flying! Andrena fenningeri is one of the most abundant in my area right now, being frequently collected on Bradford pear trees. There also happens to be a small aggregation on UArk campus of A. fenningeri with many C. inaequalis intermixed.

The gtsummary package in R makes it easy to create clean, publication-ready summary tables for your data. The tbl_summary() function takes a data set and generates well-organized tables that display key statistics like counts, percentages, means, and medians, which is perfect for

What started as a student side project became a big scientific endeavor - together with Dr. Stacey D. Smith, Leah Maier and Miranda Sinnott-Armstrong, we show that the global distribution of #flower and #fruit colors is linked to temperature and UV-B - doi.org/10.1002/ajb2.7…

Check out this weird Andrena cressonii I found a few weeks ago. Normally the clypeus is almost entirely yellow. Tho, there are a few photos with similarly mottled yellow clypeus.

New records of the eumenine wasps (Hymenoptera: Vespidae: Eumeninae) from Azerbaijan, with description of hitherto unknown male of Ancistrocerus terekensis Kostylev, 1940. Zootaxa: mapress.com/zt/article/vie…🔒

The beautiful Andrena helianthiformis. This species specializes on Echinacea, usually in decent quality areas, these individuals coming from a prairie in western Arkansas. They are quite large and conspicuous, but were not very abundant unfortunately. Hope I find more next year🤞🏽

Been a while! This beauty is Tetraloniella spissa. This species is oligolectic on Helianthus, or at least that’s what it seems. I collected this single female while on my anniversary trip to Oklahoma, along with a few other really cool bees. Look how square that face is! ⬛️
