Not sure why Tolman & Lewington needed to state specifically "Absent from Portugal" when coverage is so low around here. I take implicitly from that question that you'd actually take the challenge?

Then, following Tolman & Lewington only I get a total of 438 species as below:Papilionidae: 12Pieridae: 49Lycaenidae: 120Riodinidae: 1Libytheinae: 1Danainae: 2Nymphalinae: 71Satyrinae: 137Hesperiidae: 45    Total: 438You can easily add at least 150 species more, from WP areas not covered there (including Iran), and some splits not considered by T & L, and get to a figure roughly in the order of 600 species. Finding which authority to follow would be a first challenge actually!I guess the level of difficulty is considerably higher here than on a WP birding year and reaching 400 species would be already an absolutely amazing mark, IMO (but I might be underestimating one's determination!... and pocket size <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />). Just for starters, weather might have a huge impact on your success (as Andy was saying), something that doesn't affect birding (not in the same way), you'd need an extremely detailed schedule based on solid gen (and lots of plans B), you'd need to keep the number of localities to the very minimum, with the constraint that the number of days when each species is gettable is really low... and that those favourable periods overlap between different species occurring on areas distant from each other. A very though challenge to say the least. But just to keep you going, in Oman you have <a href="https://en.wikipedia.org/wiki/Myrina_silenus" target="_blank">this</a>. :smoke:</blockquote>
