I scanned many #insects using #microCT, but a structure that always strikes me is the #weevil proventriculus (‘forestomach’) - the cross-section of its bulb resembles an eight-pointed star. Its internal teeth are used for grinding food particles. #weevilwednesday #digestion

The first of two weeks identifying weevils at the University of Costa Rica insect collection is complete - check out this handsome Poecilogaster from Zurquí de Moravia!

Weevil workshop at the University of Costa Rica is underway! Currently identifying major groups of weevils.

I just heard early this morning that noted curculionid taxonomist Charlie O’Brien has died from Parkinson’s disease. Ypu and your encyclopaedic knowledge of weevils will be sorely missed. RIP and wherever you are I hope they have lots of green enchiladas!!

Collected some agave seed pods in hopes of finding larvae of Peltophorus adustus (Fall, 1906). Cracked a few open and there are definitely some weevil larvae in there! Immature stages are undescribed though feeding damage on the seeds has been documented.

Flattened and expanded hind tibiae occur in several genera of conoderine weevils, fanciest in the genus Tachylechriops Heller, 1895. Specimen from French Guiana.

Want to learn about these weird fighting weevils? come see my talk on “Extreme size variation, Sexual Selection and Metabolic Rates” #SICB2020 a collab with Salvatore Anzaldo Peter Marting Erin Powell, Ph.D. Dr Chrissie Painting 🍉🏳️‍⚧️🏳️‍🌈 *weevil fight videos included* Jan 4, 10:15, room: lone star C!

Eating vegetables has finally paid off! The pepper weevil, Anthonomus eugenii Cano, 1894, is a Central American species established in the southern US. This one started out in a red bell pepper in California and journeyed to a grocery store in Arizona.

Today, our @Biomedisa paper was finally published! :) The video shows a Trigonopterus #weevil that was semi-automatically segmented from #synchrotron #microCT data using the software’s semi-automatic segmentation algorithm. Check out the paper on: nature.com/articles/s4146…

It’s #WeevilWednesday! 🤩Do you want to know more about #FungusWeevils? Of course you do 😊. #Anthribidae 1/n

1. Large individuals are often not exact scaled-up versions of small ones. As body size changes so does the relative size of traits. The Jousting weevil provides an excellent opportunity to study scaling because of their extreme size variation #Animbehav2021

Males fight vigorously for mating opportunities & females mate multiply so competition likely continues in the post-copulatory arena. Does weapon size correlate negatively with post-copulatory traits? #Animbehav2021

For a deeper look showing the reversed allocation towards pre- and post-copulatory sexually selected traits in these jousting weevils here is another graphic by Peter Marting

This is one pretty weevil! Stenotherium tapinus (Cyclominae) - From South Africa; photo by Matt Buffington with MacroscopicSolutions Iziko_Museums

Exechesops frontalis (Wolfrum, 1922: 59), from Taiwan 😍. At first glance, I thought the head was missing 😅😅😆😆. #ASUCOB serv.biokic.asu.edu/ecdysis/collec…

Starting the #WeevilWorkersMeeting with an introduction from the organizers Robert Anderson, Lourdes Chamorro and @JGEntiminae, with a tour to the new Curculionoidea.org website and the #Rostrum Newsletter!

The #WeevilWorkersMeeting is coming to an end! There were two days full of great #weevils, talks, tours, and of course wonderful people! Many thanks to organizers @JGEntiminae, Lourdes Chamorro and Robert Anderson for this amazing event!! #Curculionoidea

A fun bit of detective work with @DiazGrisalesV to (re)discover the correct name for the single Heilipus species in the United States!

Not Wednesday, but always a good day for #weevils 😅. Here is one of Salvatore Anzaldo favorites, a super cute Cylindrocopturinus hainesi Hespenheide, from Mexico 🇲🇽. #Curculionidae #Conoderinae #ASUCOB #ASUBiocollections serv.biokic.asu.edu/ecdysis/collec…
