Studying "Biodiversity & Ecosystem Health" in Frankfurt am Main.

My main interest are beetles, especially central-european Curculionoidea, "weevils" (or "Rüsselkäfer" in German).
Check out my Instagram focused on Weevils: https://www.instagram.com/weevil.see/

Please do not agree with identifications (even if done by an expert) unless you can personally prove that they are correct. Everyone can make mistakes, and there is no need to push an observation to research grade without proper verification. Be aware that many species have lookalikes which aren't represented on iNaturalist yet:
iNaturalist has about 7.000 weevil species, while about 60.000 have been described!
Usually i am careful, but i misidentify from time to time. Please do not agree with my identifications without doing your own research.

I would like to recommend the DJN, a network of young (~12-27) naturalists living in Germany and nearby:
https://www.naturbeobachtung.de/
You can take part in our activities (e.g. field trips) without being a member.
Check out our recommendations on field guides and identification keys (in German, focus on Central Europe): https://www.naturbeobachtung.de/naturkunde/bestimmungsliteratur-emfpehlungen

Some helpful resources for the identification of worldwide Curculionoidea:
Most literature is assuming use of a microscope and physical specimen. Identification from images can be problematic, but those resources could help:
