In this paper, preliminary results on a field study aiming to identify predators of the Marsh Fritillary<em> Euphydryas aurinia</em> (Rottemburg, 1775) in Central Italy are presented. Several heteropterans were found on the larval nests of <em>E. aurinia</em> for dietary reasons: <em>Deraeocoris schach</em> (Fabricius, 1781) that is a predator of Marsh Fritillary larvae, <em>Palomena prasina</em> (Linnaeus, 1761) and <em>Spilostethus saxatilis</em> (Scopoli, 1763) that feed on the droppings of larvae; <em>Graphosoma lineatum</em> <em>italicum</em> (Müller, 1766) that visits the larval web during winter diapause.

AbstractThe marsh fritillary Euphydryas aurinia is declining across Europe and is of high conservation interest. Its ecology has been defined and its conservation status assessed primarily from the affinities and populations of young caterpillars in the autumn, before hibernation and high winter mortality. The possibility that caterpillars of E. aurinia can overwinter more than once was investigated on the Isle of Islay, Scotland after caterpillars were found to occur at some locations in the spring despite a pre-hibernation absence. Closely-related species in North America and Northern Europe can prolong larval development by diapausing for a year as does E. aurinia in Scandinavia. Measurements of development and manipulations of distribution confirmed that some caterpillars do extend the life-cycle in Scotland and may occur in areas devoid of larvae in their first year. Caterpillars attempting this life-cycle develop slowly in spring, attain the normal penultimate spring instar and then enter diapause while other caterpillars are pupating. They moult just before diapause, construct highly cryptic webs and on emergence the following spring are 5–6 times heavier than larvae emerging in their first spring, or the equivalent of a month or so ahead. They attain a final, extra instar as larvae in their first spring reach the penultimate instar. Knowledge of this life-cycle is confined in the UK to Islay but its occurrence in this mild climate implies that it is more widespread.Implications for insect conservation Conditions that permit long diapause are probably precise and may not be reflected in recognised qualities of habitat. The species may also be present despite a perceived absence in autumn, the standard period for monitoring. Assessments of the prevalence of the life-cycle and its contribution to the persistence of E. aurinia are required. Populations of E. aurinia are known to fluctuate greatly and do occur below the observation threshold for long periods.

Marsh Fritillary

Thirty colonies of the Marsh Fritillary (Euphydryas aurinia) have recently been recorded in Western Bohemia, Czech Republic. The majority of colonies are small, their total area are 1.5 km2. Small size and intensive grazing/mowing were positively associated with observed declines/extinctions, while abandonment threatens the colonies in the longer term. Short distances to nearest colonies buffered against declines. High colony turnover, asynchronous local dynamics pointed and the species’ biotope requirements all point to a dynamic metapopulation structure; patterns of connectivity revealed that there are several metapopulations within the region. Because conserving the species within its extant sites seems unsustainable in the long term, restoration of its habitats is proposed.

Index Value

Knowledge of a carnivore’s foraging behaviour is essential to understand its ecology. The pine marten Martes martes is commonly defined as an opportunistic generalist predator since its diet in Europe includes mammals, fruits, birds and invertebrates. Based on faecal analyses, we evaluated spring feeding habits and trophic niche breadth of the pine marten in a Mediterranean landscape on the island of Sardinia (Central Italy). The most important source of food for the pine marten was small mammals (mainly Apodemus sylvaticus, Mus musculus and Eliomys quercinus), accounting for 52% of the percent mean volume. Important secondary foods were invertebrates (mainly beetles and insect larvae) and birds (almost exclusively passerines), whereas large mammals, lagomorphs, reptiles and fruits made little contribution to the diet. The diet composition and the Levins’ index value suggest that the pine marten in Sardinia behaves as a facultative specialist predator, with a specialization towards small mammals.

The chamois in the Appennine Mountains of central Italy are reduced to under 400 animals scattered in a few places in the Abruzzo National Park. Shooting outside the park and the presence of livestock and shepherd dogs make it impossible for the chamois to spread. A field study is now being made and reinrroductions are planned.
