Welcome to the Malta BMS!


This window is for the information of the Maltese Butterfly Monitoring Scheme, BMS to monitor Maltese butterflies.


Be part of the eBMS community counting Butterflies! 



Please, contact the coordinators before starting a transect, they can help you where to do your transect and give advice on butterfly monitoring.

If you would like to participate in monitoring butterflies in Malta, contact the coordinators: Prof. Louis F Cassar or to




The basic methodology for a BMS is the Transect, a fixed route that is visited frequently to count butterfly species present and their abundances. Thanks to this method of repetitive counts we count to determine the butterfly trends and their current status. Help us in the protection of butterflies doing a transect close to your house or working place like thousand of volunteers in Europe. See more information on how to do a transect on the page Methods.

There are other methodologies to count butterflies, like the 15-min Counts collected through the ButterflyCount mobile application, where your GPS tracks your route while counting butterflies for 15 minutes. All the data collected on this website will be shared with the Latvia BMS.


This free resource makes it easy to keep track of what you see, while making your data openly available for scientific research, education and conservation.

Monitoring Material

- Field Guidesmalta

A field guide to identify 30 butterfly species in Malta, with illustrations of the more recognizable species. This Guide aims to be useful for identifying butterflies in the field in an easy and simple way. Butterflies are divided by families, presenting symbols to mark specific characteristics with which to identify them and with information about ease to see them. Also, this Guide includes an explanation of the methodologies to monitor butterflies (transects and 15-min Counts).

You can download the pdf guide Field Guide Malta directly to your device or print it directly (select the booklet option in the printer) in two languages:
