What is the BMS?

BMS, is the Butterfly Monitoring Scheme, which is responsible for monitoring butterfly species using methods shared with all of Europe, mostly with transects. The BMS aims to assess the abundance of butterfly populations, to establish adequate conservation strategies thanks to the efforts of many volunteers. If you like butterflies and spend time outdoors join us at BMS Spain, share your passion for these beautiful insects with all Europeans, collaborating with citizen science.

Butterfly Field Guides for Identification in Spain


sp_fieldguidesCommon species Spain

Spain is a diverse country with different climatic zones where there are at least 258 butterfly species; great diversity, and challenge to monitor. For that reason, a new Field Guide of the Spanish Common Species has been created to facilitate the identification of the 105 most common species in the country, including Canary species. Like the rest of the Field Guides, you can find a nice and logical order of the species, pointing out and highlighting important characteristics to identify properly the species. 



This Field Guide includes 93 of the most common butterfly species in Andalusia in just 12 pages. This Guide aims to be useful by reducing the number of butterflies in an area as rich and diverse as Andalusia, a Mediterranean area with an African influence and peculiar endemisms. You can download the guide in PDF in various formats:


Castilla-La Mancha

Castilla-La Mancha is a region of the peninsular center of Spain with a great diversity of ecosystems. It has a large number of butterfly species, with a total of 157 species in the whole region, being the 67.4% of the peninsular total. You can see the Complete list of butterfly species from Castilla-La Mancha (CLM) in this pdf. You can download the CLM Field Guide guide in pdf format with the 72 most common butterfly species in CLM in 8 pages.



You can now download the butterfly identification booklets that we have designed for the BMS implementation project in the Natural Parks of Galicia on its website:

Butterfly Identification Guide from the European Butterfly Group 









The BMS Spain is coordinated by the Universidad Autónoma of Madrid (UAM), with the collaboration of the Autonomous Organization of National Parks (OAPN), Biological Station of Doñana, and various National Parks. There are coordinators for various regions of the country who help coordinate the different volunteers and in general the entire BMS. The logos belong to different organizations and institutions that collaborate with BMS Spain. Thanks to all of them.
