Welcome to Spain BMS

This tab provides specific information about the Spanish and Andorran butterfly monitoring schemes.
Currently, 4 independent butterfly monitoring schemes in Spain form part of the eBMS network. While all use the standard eBMS monitoring methodologies and share their data with eBMS, they differ in the lead organisation that coordinates each and the geographical area they cover. The 4 BMSs of Spain are:
SOCEME, the Society for the Conservation and Study of Butterflies in Spain.
Catalan Butterfly Monitoring Scheme (CBMS), which also encompasses BMSAnd, monitors butterflies in Catalunya, the Balearic Islands, and Andorra.
Zerynthia, the Spanish Association for the Protection of Butterflies and Their Environment.
UBMS, the Urban Butterfly Monitoring Scheme.
Scroll down to read more about each monitoring scheme. At the bottom of this page, you will also find materials and resources for identifying and monitoring Spanish and Andorran butterflies.

SOCEME
The Society for the Conservation and Study of Butterflies in Spain (Sociedad para la Conservación y el Estudio de las Mariposas en España) has its own official website, where you can find additional information.
This monitoring scheme began collecting transect data in 2014, and currently collects 15-minute and moth trap data as well. It continues to grow and support butterfly conservation thanks to the efforts of the scheme's coordination team: Saba González Lorenzo, Cecilia Montiel, Fernando Jubete, Amparo Mora Cabello de Alba, Sandra Ruzafa Pérez, Sergio Montagud, Cristina Pérez, Cristina González Sevilleja, David Gutiérrez Garcia, Juan Ignacio de Arce Crespo, Rocío Fernández Zamudio, Juan Gallego Zamorano and Raúl León Vigara.

The coloured areas in the map above show the areas of Spain where SOCEME coordinates butterfly monitoring. Different colours indicate areas coordinated by different coordinators. Other BMSs (Zerynthia or CBMS) monitor the uncoloured territories. Click here to view the interactive version of this map.

Getting started - Contact SOCEME
Please contact the coordinators before starting a transect, they can help you place your transect and give advice on butterfly monitoring.
Please contact [email protected]. You can also find the coordinator for your geographic area on the interactive map and contact them directly.
If you have problems or suggestions specifically regarding the eBMS app or website, please contact eBMS by writing [email protected].

CBMS - Catalan Butterfly Monitoring Scheme
CBMS has its own official website, where you can
find additional information.
This monitoring scheme began collecting transect data in 1994, and continues to grow and support butterfly conservation thanks to the efforts of the scheme's coordination team: Constantí Stefanescu (Scientific coordinator and researcher), Andreu Ubach (Technical coordinator, data analysis, postdoc) and Laia Moret (Volunteer coordinator). CBMS is supported by the Generalitat de Catalunya, Diputació de Barcelona and Observatori de la Biodiversitat.

This monitoring scheme collects all transect count data via its official website.
CBMS only uses the eBMS website and the ButterflyCount App to collect 15-minute counts and moth trap observations.
CBMS coordinates butterfly monitoring in Catalunya and the Balearic Islands in Spain, as well as across Andorra. The map to the left highlights the geographical area encompassed by this BMS and shows the position of its transects. Click here to view the interactive version of this map.
BMSAnd - Andorran Butterfly Monitoring Scheme
The Catalan Butterfly Monitoring Scheme encompasses BMSAnd, which coordinates butterfly monitoring in Andorra. Initiated in 2004, this scheme has its own coordinators and website, and publishes separate annual reports, but is considered part of CBMS because it collects its transect count data through the CBMS website.
Getting started - Contact CBMS
Please contact the coordinators before starting a transect, they can help you place your transect and give advice on butterfly monitoring.
Please contact [email protected].
If you have problems or suggestions specifically regarding the eBMS app or website, please contact eBMS by writing [email protected].

UBMS - Urban Butterfly Monitoring Scheme
The Urban Butterfly Monitoring Scheme (Observatorio ciudadano de mariposas urbanas) has its own official website, where you can find additional information:
Unlike other monitoring schemes, and as its name suggests, this BMS focuses on collecting data about butterflies in urban areas. It currently collects transect count data in the urban areas of Madrid and Barcelona.
This monitoring scheme collects all transect count data via its official website.
This monitoring scheme began collecting butterfly data in 2018, thanks to financial support from the Fundación Biodiversidad. It has continued to grow and support butterfly conservation since 2019, thanks to the Ajuntament de Barcelona and the efforts of the coordination team: Yolanda Melero, Pau Guzmán and Paco Cabrero.

Supporting materials and resources
Below are field guides and other useful resources to help you identify the butterflies present in your geographical area. If you are instead looking for materials about broader butterfly group identification or about butterfly count methodologies, please visit the materials tab.
Identification guides
eBMS and ABLE species identification guides
Common species in 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.
Diurnal moths Field Guide of Spain in Spanish
Andalucía
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:
- Andalusia Guide (Spanish): to print directly, Andalusia guide by pages (Spanish): pdf with individualized pages to download to your device or print
- Andalusia Guide (English): to print directly, four sheets to be printed on both sides, the pages are ordered for printing.

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.
