Once a dedicated birdwatcher, I now focus more on entomology (Grasshoppers and Bees).
I mostly keep track of and share my sightings using the very good Inaturalist. I'm a big fan of Inaturalist, it's a great tool for sharing observations but also for teaching, learning and socializing. For identification problem, I rely extensively on the help of the insecte.org forum (in French).
