I realized that almost 90% of recorded rhino beetles for Iran are in the north of Iran.Well,there in the west too or they are only in the areas with ?forests
You can look at the map of observations, they seem to have been observed across the country: https://www.inaturalist.org/observations?place_id=6818&preferred_place_id=6883&subview=map&taxon_id=136361
They do seem to be a bit more in the forests and around Tehran but that’s also where the most people are so hard to say if that’s a result of habitat or not. Oryctes elegans and agamemnon are apparently pests on date palms so theoretically they could occur wherever the palms are cultivated.
I suspect there are very few people on this Forum who know much about Iran, unfortunately, so most people replying to your questions are just using the Explore page on the iNaturalist site. What are you hoping to learn that you can’t find on the iNaturalist website itself?
