Species Identifications: Common Pitfalls
Some thoughts about Identifications. How do we identify properly? How do we avoid mistakes?

I started a blog and my first post is online!
The posts will try to explore topics which are not typically covered by introductory literature and textbooks, e.g. because they are considered to be "too basic". Let me know what you think!

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!

it took one (1) question for the amazing new agentic LLM iChatBio to start fabricating data out of nothing. I asked for a list of clam shrimp in Florida, and it skipped a whole genus. when I told it that it was missing one, it confidently replied that Cyzicus also lives in Florida (it doesn't).

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

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.

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.

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
