“…Rather than being a “ sabuleti type” (as exists in Poland 15 ), the high estimated survival of P. rebeli in nests of both M. schencki and M. sabuleti suggests that the population at Campitello and Collelongo are genuinely more generalist 24–26 . Multiple-host using P. rebeli at Campitello and Collelongo suggests that, while rare, there are some populations where these social parasites are less specialised 36–38 than reported from the vast majority of populations studied in the past 22 . An alternative explanation could be that we failed to distinguish between two differentiated, specialist host races that live sympatrically on rare occasions but are otherwise cryptic, comparable to the co-existence on many sites of the non-cryptic Phengaris species, P. teleius and P. nausithous , which share the same food plant but generally exploit different species of Myrmica .…”

“…It has been suggested that European populations became isolated during glaciations in refuges in the Southern Alps, Western Hungary and South-Eastern Europe 39 , where different host associations may have evolved in isolation 40 . Re-colonising the continent, the different host types could have given rise to the specialised populations in Western 22,31 and East-Central Europe 36–38 . Within such a scenario, the Alps can be regarded as a geographical and genetic barrier for butterflies, separating Italian and French populations.…”

In natural ecosystems, relationships between organisms are often characterised by high levels of complexity, where vulnerabilities in multi-trophic systems are difficult to identify, yet variation in specific community modules can be traceable. Within the complex community interactions, we can shed new light on dynamics by which co-evolutionary outcomes can inform science-led conservation. Here we assessed host-ant use in six populations of the butterfly Phengaris (=Maculinea) rebeli, an obligate social parasite of Myrmica ants and a model system in evolutionary and conservation ecology. Starting from the initial distribution of eggs, we estimated the survival of the parasite in the wild in nests of seven Myrmica ant species, and analysed the chemical cues evolved by the parasites to subvert its host defences. We found local variations in host specificity that are consistent with similarities found in the chemical profiles of hosts and parasites on different sites. At some sites, only one ant species is successfully exploited; at others, multiple-host populations are used. Understanding how stable or adaptable these associations are is essential knowledge when devising conservation measures to maintain keystone species of ant and locally adapted populations of Phengaris butterfly species, which are rare, threatened and a high priority for conservation worldwide.

“…While P. alcon in some areas of its distribution shows high specificity to only one Myrmica species (Arnaldo et al 2011) in other areas more ant species can be involved (Witek et al 2008). Moreover, some studies report that in some areas different species of Myrmica serve as primary and secondary hosts of P. alcon larvae (Steiner et al 2003, see also Tartally et al 2008). Wynhoff et al (2014) reported for the Portugese population of P. alcon that the proximity of host plants to the nearest host ant nest was positively correlated with oviposition site selection.…”

“…Finally, all detected Myrmica spp. represent potential hosts for endangered Phengaris Doherty, 1891 lycaenid butterflies [76,77], that are present in Northern Italy and were recorded in some of the investigated parks (e.g., [78,79]).…”

Ants are considered a useful model for biodiversity monitoring and several of their characteristics make them promising for citizen science (CS) projects. Involving a wide range of public figures into collecting valuable data on the effect of human impact on ant biodiversity, the School of Ants (SoA) project represents one of the very few attempts to explore the potential of these insects in CS. Through the collaboration with the “BioBlitz Lombardia” project, we tested the SoA protocol on 12 Northern Italy parks, ranging from urban green to subalpine protected sites. As a result, we obtained some of the very first quantitative data characterizing the ants of this region, recording 30 species and highlighting some interesting ecological patterns. These data revealed the ubiquitous presence of the recently taxonomically defined cryptic species Tetramorium immigrans, which appears to be probably introduced in the region. We also discuss advantages and criticisms encountered applying the SoA protocol, originally intended for schools, to new categories of volunteers, from BioBlitz participants to park operators, suggesting best practices based on our experience.
