At first glance all the individuals of Roslia alpina can seem the same, but instead they are all different. Indeed, the pattern of coloration of the elytra is different for each one. This characteristic was used in an approach of photographic identification of individuals and described in the paper recently published on the journal Insect Conservation and Diversity by the researchers of the MIPP project. Usually population estimates are based on the capture-mark-recapture method in which the individuals are captured marked and released, marking the individuals the researchers ensure to do not count twice the same individual. To try to reduce the stress for beetles during the handling and marking procedure the researchers of the MIPP used a software that allows the identification of individuals by pictures taken of the elytral pattern of coloration. This method was tested on the pictures of two years of work at ‘Parco d’Abruzzo’ and ‘Foreste Casentinesi’ and succeeded in giving the corrected identification of individuals.
