The category for this would be "recording" but since there isn't such a category I'll put it here:
I've been trying out the iNaturalist project system for a month now at https://www.inatu...tanypezids and whilst the flies are in season, records are coming in at 3 or 4 per day. So at the very least it's entertaining, with the occasional cracking photograph. Distribution patterns are beginning to emerge.
Easy to set up, little effort to manage (depending on the popularity of the Family), not much obligation and colleagues can join the project to collaborate.
The only other one I know of is Valter Jacinto's Diptera of Europe (https://www.inatu...-of-europe) which covers everything.
Would any of the other Diptera experts care to set one up? I'd like to visit ones on Conopidae or Sciomyzidae each day too.
