Butterfly monitoring is vital for assessing butterfly population trends and to understand the causes of change. Over several decades and in many countries, butterflies have been monitored regularly and has produced many insights to support their conservation.

To support further development of butterfly monitoring, we have produced the following guide.

Manual for Butterfly Transect Counts

Transect counts are the main method used in the European Butterfly Monitoring Schemes.  You can download the Manual for Butterfly Transect Count to learn how to use this method. In this Manual you will find useful information about monitoring butterflies with the transects including: how to select a place to monitor, where to setup your transect route, which simple rules to follow for a transect visit and how to submit your records. 

This Manual has been adapted for the following languages:

          - Portuguese

          - Polish (a Manual adaptation for Poland)

          - Spanish 

          - Italian 




Field Guides for butterfly Identification

Many countries in Europe are very rich in butterfly species and identifying butterflies is a real challenge. In Italy there are around 290 species and the lack of identification guides were a problem. Together with the Italian Butterfly Group we divided Italy into climatic regions and selected the 72 most common species in each. We eventually produced 4 different Field Guides from specific regions: Padana plain, Mediterranean area, Apennines and Mediterranean Islands. We translated the text, organised the species by families and genus and showed special characteristics to enable correct identification. You can download the guides from here and print them directly.

How to print the Field Guides: 

The pdf has 4 pages that you can print in two sheets for both sides. 

The order of the pages are organised to print them directly. 

When you have the two sheets printed, just fold the sheets for the middle and organise them following the number of the pages. 






Booklet Common Species Portugal Continental

This guide illustrates 60 common butterfly species in Portugal Continental and it is a great help for those just beginning to identify butterflies and want to participate in the Butterfly Census of Portugal. This booklet was produced with the ABLE project and with the help of Tagis - Centro de Conservação das Borboletas de Portugal
