Future 4 Butterflies in Europe

Dutch Butterfly Conservation
11-JUL-2017 - In 2016, the fourth symposium ‘Future of Butterflies in Europe’ was held in Wageningen. Now a selection of papers from that meeting is published in the Journal of Insect Conservation.

Maculinea teleius (Phengaris)The meeting was held from 31st March to 2nd April 2016 and organised by Michiel WallisDeVries, Chris van Swaay and Irma Wynhoff. Of the eight papers in this Special Issue, five are on various aspects of the Phengaris/Maculinea group of butterflies. Timus et al. explored source-sink dynamics for Phengaris nausithous and Phengaris teleius in central Transylvania, Romania. Wynhoff et al. , also working on Phengaris teleius, explored the impact of fen meadow restoration via a LIFE+ project in the Netherlands using the interesting approach of using transplanted fen sods from mature meadows as a way of facilitating host ant colonisation. Vrabec et al. examined the potential impact of a waterway development on populations of Phengaris teleius and Phengaris nausithous in the Czech Republic whilst Popović et al. reported on studies in Serbia on Phengaris teleius, where it is at the edge of its northern European distribution. Finally, Osváth-Ferencz et al. examined the population demography of Phengaris arion in four European countries (Italy, Romania, Poland and Hungary).

Poster session at the Future 4 Butterflies symposium in WageningenThe three remaining papers cover different aspects of butterfly conservation. Munguira et al. addressed the development of management plans for the four endangered Spanish endemics Polyommatus violetae, Polyommatus golgus, Agriades zullichi, and Euchloe bazae. Essens et al. analysed the vulnerability of 397 of the 482 European species by incorporating data on life-history and climate niche traits in vulnerability analyses. They concluded that mobility, development rate, and overwintering stage traits were preferable to using the generalist-specialist axis to identify vulnerable species. Vantieghem et al. analysed the quality of citizen science data using skipper butterflies. Such data provide a substantial and important component of distribution mapping, but misidentification of species can have important consequences. In their study system of three skippers, Ochlodes sylvanus, Thymelicus lineola and Thymelicus sylvestris, they demonstrated that misidentifications of the latter species resulted in an overestimation of its distribution and concluded that strong quality control checks were needed in the use of such data.
