The Pieridae of Morocco, by Michel Tarrier, full english translation (USA) by Pietro Galassetti, is available as E-book with private URL and in Portable Document Format (PDF) for the promotional price of 14€!
148 pages, 212 pictures... and 31 years of field work!
This publishing, in the form of a richly illustrated monography, includes the additions of the species and subspecies discovered and /or described since 2008, date of publication of my former book "The butterflies of Morocco", as well as an update of the recent systematic and taxonomy reviews, and biological and goenemical knowledge. But perhaps the most interesting for you is the complete compilation of useful places to collect in Morocco!
