In 2017 I went for a walk in the nearby woods and found this seemingly unspectacular Click beetle. And for the most of 3 years the photo just lay dormant on my computer.
I added it to iNaturalist.org, because I really couldn’t find out what it was, and there it turned out to be the very rare Porthmidius austriacus.
Even on GBIF they made a feature page using my data and this image.
So I guess I got lucky.
A very rare species, widespread but rare.
