The (free) registration for The Online Weevil Workers Meeting 2025 on October 17 is open!

To keep track with everything, we love to make lists. They give us the illusion of order in a chaotic reality.
For this project, there is a large database in the background (TaxonWorks), and a data portal as frontend (TaxonPages: curculionidae.github.io/taxa)

You can now explore host-plant associations on "Curculionidae of the World Online"!
We have almost 3000 associations in the database.

Huge thanks to the team of TaxonWorks who got the Biological Associations tab for TaxonPages running with the latest release!

A summary of Agave weevils!

Meet Peltophorus polymitus, the Agave Stem Weevil!
- Larvae develop in the stem of different Agave species (often A. palmeri)
- When disturbed, the weevils will drop into the thorny depth of their host plant
- found in Mexico and the SW of the USA
- This specimen was found by Salvatore S. Anzaldo

For me it is always fascinating to be able to locate such tiny insects through their host plants. They are as reliable as a postal adress!

How to find Mogulones crucifer:
The weevil is native to Europe/West Asia, but has been introduced to North America to control its host (Cynoglossum officinale; Hound's Tongue) which is invasive there.

I'm writing my master's thesis in the lab of Marianna Simões at the Senckenbergmuseum in Frankfurt. Its very inspiring to see how the team has been growing in numbers and is exploring new research areas
The lab is now on instagram, follow for updates: www.instagram.com/msimoeslab/

A velvet worm (Onychophora: Peripatidae) in Chiriqí (Panamá). I was incredibly amazed to find this specimen under a bunch of logs and stones, but had to suppress my urge to frantically turn logs after realizing how dangerous some snakes in the area are...

This is how I find twiglet weevils (Acalles and related genera) in Central Europe. Weevils with comparable ecology are found wordwide, you can try it no matter where you are.
When beating twigs, be swift and careful, as they will drop to the ground at the slightest disturbance.

Trying to recycle instagram-content here:
Seems like only 4 slides at a time can be posted here.
What's missing are the slides where I tell how I tried to use CO1-barcodes to test if there are two separate species. I found no evidence but my study was VERY limited...

I already run an instagram on weevils (@weevil.see) but wanted to give Bluesky a shot.
So here's my first post: Chlorophanus viridis
The species is widespread in Germany, but according to Rheinheimer & Hassler has become rarer for unknown reasons. You'll find it in damp habitats, and its polyphagous
