@LoliRod77701434 @txaverius No, este es una obera o reina de una especie del subgenero Bombus s.str., probablemente B. terrestris.

@txaverius Puede ser éste?

Acabo de acordarme del amenazadísimo abejorro nevadense (Bombus reinigiellus), un endemismo Bético. ¿Alguien sabe si sigue en este mundo?

[#Hymenoptera] 🐝 Bumblebees with big teeth: revising the subgenus Alpigenobombus with the good, the bad and the ugly of numts (Hymenoptera: Apidae) ✒️ @PaulWilliamsNHM et al. @NHM_London 🔗 DOI: doi.org/10.5852/ejt.20… #Bumblebees #Apidae #hymenopterist

@wurflenii @PaulWilliamsNHM If you decide to switch platform, since everybody seems to be leaving this one right now, you get a new chance ;-)

@MStreinzer @PaulWilliamsNHM Funnily enough, I've actually entertained using mastrucatus as my original handle, but decided against it after looking up what it means! Would I have even earned a follow by Paul in that timeline, considering this name was widely used as a 😱subspecies😱 back then?

B. mastrucatus returns to the European bumblebee list as a separate species from the west Asian B. wurflenii after 54 years in synonymy - supported by barcode coalescents and morphology researchgate.net/publication/37…

@PaulWilliamsNHM @wurflenii Right, but still some work since I usually add an accession number label (in addition to the number being printed on the other labels too) upside down as the lower-most label in my collection ….

@MStreinzer @wurflenii Ideally ID det labels would have a date on them - so all that is needed (if you're being really thorough) is to add a new ID label to the bottom of the pin dated 2023 - this allows people to track a specimen's history of interpretation through the sequence of labels on the pin

Hallo, MA42! Viele kannten den Wiener Baumkataster noch nicht. Alle, die heute auf Twitter drauf aufmerksam wurden, sind begeistert. @ChairNoHorseKey

We had a fantastic day in the field studying #thermal biology of #bees in the paramo! 🏔️ Both #Bombus rubicundus and B. funebris are key pollinators of keystone paramo plants #Espeletia. Even bee males do a lot of pollination! @lopezuribelab @beaslab #NSF

Currently revising the steppe bumblebees of the subgenus Sibiricobombus world-wide - here, Fabricius' 1781 type of Apis sibirica, collected by Peter Pallas in Siberia, and now in the Banks collection at the NHMUK

How a book written in 1910 could teach you calculus better than several books of today [Calculus Made Easy, by Silvanus P. Thompson, 1910 - full text pdf: bit.ly/2pThkf1 or with the table of contents: calculusmadeeasy.org]

@cgwilson25 @PaulWilliamsNHM You can easily soften it again to pull out the genitalia. Put it in a moist chamber (you can add a few drops of ethyl acetate to prevent mould) for a few days, pull out the genitalia and dry it again. Any reasons to assume this is not citrinus?

@PaulWilliamsNHM Unfortunately, I didn't pull the genitals :/ this was in my early days of collecting (two years ago)

Any ideas? Collected in NY two years ago on Helianthus. Definitely Psithyrus. REALLY hoping it isn't what I think it is... 😬

@PaulWilliamsNHM @McCluskeyDavid @JeffOllerton @StevenFalk1 Also in the E-Himalaya (Arunachal Pradesh, India) there are more and less perfect mimics: B (Ag) #9, B (Or) funerarius, B (Pr) parthenius (left to right)

@MStreinzer @McCluskeyDavid @JeffOllerton @StevenFalk1 Close and less close mimics? - from southern Sichuan: top left B (Or) funerarius, top right B (Alpigenobombus) #9, bottom left B (Pr) avanus, and bottom right B (Pr) infrequens @MStreinzer @McCluskeyDavid @JeffOllerton @StevenFalk1

Christmas quizz - NAME THAT BUMBLEBEE! - hint: thanks to (11) co-authors of a new revision of Alpigenobombus now submitted cc @JeffOllerton @StevenFalk1

The hypnorum-complex of bumblebees has been interpreted as a single widespread Old-World species, B. hypnorum, and its New World sister species, B. perplexus, but is shown here to be 7 near-cryptic species - 2 of them newly described researchgate.net/publication/36…
