Le farfalle delle zone speciali di conservazione IT5190008 Lago di Montepulciano e IT5190009 Lago di Chiusi (Toscana) (Lepidoptera Papilionoidea).
No full textButterflies of the IT5190008 Lago di Montepulciano e IT5190009 Lago di Chiusi (Tuscany)’s special areas of conservation (Lepidoptera Papilionoidea). Unpublished data collected between 1990 and 2022 and bibliographic and website data updated to 2023 on the rhopaloceran fauna of the lake of Montepulciano and lake of Chiusi, two special areas of conservation (92/43/EEC) in southern Tuscany, showed 57 and 64 species. The most significant species for conservation value and interesting because they are not so common elsewhere in southern Tuscany are Zerynthia cassandra (Geyer, [1828]), Cupido argiades (Pallas, 1771), Apatura ilia ([Denis & Schiffermüller], 1775) e Nymphalis antiopa (Linnaeus, 1758). The carrying out of late mowing of the herbaceous vegetation (in October-November) carried out in rotation on plots of reduced surface area alternating over the years and the monitoring of the species are fundamental measures for ensuring the survival of the rhopaloceran fauna of the Lago di Montepulciano and Lago di Chiusi, in particular of the populations of Zerynthia cassandra (Geyer, [1828]), few in number in Chiusi and probably declining in numbers in Montepulciano
I Ropaloceri del Monte Amiata (Toscana)
Full text linkTwenty five years of research (1994-2019) on the rhopaloceran fauna of the Monte Amiata, integrated with bibliographical sources, showed 89 species. The most numerous species are those that live in the forests, those linked to the edges of the woods and those that prefer high-hill and mountain areas. The most significant species for conservation value, biogeographical interest and because they are not so frequent elsewhere in Tuscany and in Italy, are Hamearis lucina (Linnaeus, 1758), Satyrium w-album (Knoch, 1782), Cupido argiades (Pallas, 1771), Argynnis pandora ([Denis &
Schiffermüller], 1775) and Brenthis hecate ([Denis & Schiffermüller], 1775)
Il genere Hipparchia Fabricius, 1807 in provincia di Siena (Toscana meridionale) (Insecta: Lepidoptera: Nymphalidae: Satyrinae)
Full text linkThe genus Hipparchia Fabricius, 1807 in the province of Siena is represented by three species: Hipparchia fagi (Scopoli, 1763), Hipparchia semele (Linnaeus, 1758) e Hipparchia statilinus (Hufnagel, 1766). Hipparchia fagi is widespread; attends mostly woods, between a minimum of 150 m up to 895 m altitude, with flight time between the first fortnight of June and the first fortnight of October. Hipparchia semele is poorly distributed; attends mostly natural grasslands and
pastures, between a minimum of 290 m and a maximum of 1015 m above sea level, with flight time between the second fortnight of June and the second fortnight of September. Hipparchia statilinus is widespread; attends mostly woods and natural grasslands, between a minimum of 170 m and a maximum of 1148 m above sea level, with flight time between the second fortnight of June and the first fortnight of October. At present, no risk factors are known to threaten these species in the Siena district. For the protection of their populations it is suggested to keep the woods, the prairies and the
meadows-pastures
Il genere Carcharodus Hübner, 1819 in provincia di Siena (Toscana)
Full text linkThe genus Carcharodus Hübner, 1819 in the province of Siena is represented by three species: Carcharodus alceae (Esper, [1780]), Carcharodus floccifer (Zeller, 1847) and Carcharodus lavatherae (Esper, [1783]). C. alceae is widespread; attends mostly natural grasslands and pastures, between a minimum of 165 m and up to 890 m altitude, with flight time between the first two weeks of April and the first fortnight of October. C. flocciferus is poorly distributed; attends mostly natural grasslands and pastures, between a minimum of 165 m and a maximum of 850 m above sea level, with flight time between the first two weeks of May and the first fortnight of October. C. lavatherae is rare; attends mostly natural grasslands and pastures, between a minimum of 165 m and a maximum of 750 m altitude, with flight time between the first two weeks of May and the first two weeks of August. For the protection of the populations of these species, it is advisable to keep natural grasslands, pastures, fallow plots and marginal areas, such as road and railway embankments,
disused quarries, former industrial land and bands of respect of cemeteries
Le praterie xerocalcicole della Toscana meridionale, habitat di rilevante interesse per la fauna a Ropaloceri
Full text linkWe studied the Lepidoptera Rhopalocera of calcareous grasslands of southern Tuscany, habitats of community interest in conservation priorities in accordance with Directive 92/43/EEC. Were examined six areas in the provinces of Livorno (Monte Calvi), Siena (Le Cornate and Monte Cetona) and Grosseto (Monte Calvo, Le Cornate, Monte Labbro and Monte Civitella) with significant extensions of grasslands (> 15 ha). The study showed that these grasslands are important areas for lepidotterofauna hosting 108 species of which 25 (23.1%) of conservation interest. In particular the Monte Calvo, Le Cornate, Monte Labbro, Monte Cetona and Monte Civitella are distinguished by 156 the presence of rich populations of “target species” Maculinea arion (Linné, 1758) and Melanargia arge (Sulzer, 1776) justifying their inclusion among the “Prime Butterfly Areas”. Even xerocalcicole grasslands of southern Tuscany as European ones are gradually reducing, and in few years could disappear. For their maintenance is suggested the application of management standards including: the recovery of extensive grazing and planning by calculating the “carrying capacity”; alternating grazing areas with annual rest areas; mowing the grass vegetation through haymaking diluted over time of limited surfaces; the reduction of herbaceous vegetation by means of controlled winter burns; the limitation of the development of shrubs through periodic cuts
Pyrgus sidae (Esper, [1784]) in Toscana
No full textReports published between 1869 and 2023 and unpublished records collected between 1971 and 2023 suggest that Pyrgus sidae (Esper, [1784]) is a rare species with a restricted distribution in Tuscany. Indeed, it is only known from about twenty sites in 17 10x10 UTM squares which are reduced to 9 if only those covered with reports relating to the period 2000-2023. It lives from 70 m of 1029 m and flies between the first half of May and the first half of July. It frequents pastures and permanent meadows and above all xeric prairies, habitats of community interest and priority pursuant to Directive 92/43/EEC. To know the actual distribution of this species in Tuscany it is necessary to sample more accurately the central north of the region and confirm its presence in the localities where it was ascertained before 2000, in particular in those where it was collected between the second half of 1800 and the first half of the 1900s

Per la provincia sono riportate 115 specie (Papilionidae: 3; Hesperiidae: 18; Pieridae: 13; Riodinidae: 1; Lycaenidae: 34; Nymphalidae: 46). Le specie più interessanti dal piunto di vista conservazionistico e biogeografico sono Carcharodus baeticus (Rambur, 1839), Iolana iolas (Ochsenheimer, 1816), Lysandra hispana (Herrich-Schäffer, 1851), Hipparchia aristaeus (Bonelli, 1826) e Coenonympha corinna (Staudinger, 1901). Gegenes nostrodamus (Fabricius, 1793), Carcharodus lavatherae (Esper, 1783), Pyrgus sidae (Esper, 1784), Lycaena thersamon (Esper, 1784), Thecla betulae (Linnaeus, 1758) e Satyrium w-album (Knoch, 1782) rivestono un certo interesse in quanto considerate in declino nella Lista Rossa italiana
Barbus tyberinus Bonaparte, 1839, Telestes muticellus (Bonaparte, 1837), Squalius lucumonis (Bianco, 1983) e Padogobius nigricans (Canestrini, 1867) nel versante tirrenico del Parco Nazionale delle Foreste Casentinesei, Monte Falterona e Campigna (Emilia Romagna - Toscana)
No full textIn 2016 and 2017, a survey was carried out in the streams of the Tyrrhenian side of the Foreste Casentinesi, Monte Falterona and Campigna National Park, in the upper Arno River basin, with the aim of deepening knowledge on the distribution, consistency and conservation status of the population of Barbus tyberinus Bonaparte, 1839, Telestes muticellus (Bonaparte, 1837), Squalius lucumonis (White, 1983) and Padogobius nigricans (Canestrini, 1867). These four species, endemic of italian fauna, are in continuing decline. 43 stations were sampled in 25 streams, in ten of which, corresponding to seven streams (Staggia, Oia, Fiumicello, Archiano, Corsalone creeks and Camaldoli and Corezzo brooks), the presence of the species under investigation was ascertained. T. muticellus was the most widespread, present in all seven streams with the largest and best structured populations; B. tyberinus sampled in the Corsalone creek and in the Corezzo brook had numerous and well structured populations only in the first stream; P. nigricans which has never been found before in the streams of the Park, this species is present with populations quite numerous only in the sections at lower altitudes of the Archiano creek and Camaldoli brook; S. lucumonis, like P. nigricans, is new to the Park, the species has resulted sporadic in the Corsalone creek. The greatest threat for the conservation status of these species is the predation/competition carried out by Salmo trutta, Linnaeus, 1758, which was introduced for support the purpose of recreational fishing. © 2021 Societa Toscana di Scienze Naturali.

Rediscovery of a species considered to be extinct in the Pollino massif (Calabria, Italy): Erebia gorge (Hübner, [1804]) (Lepidoptera: Nymphalidae)
No full textAfter about 40 years, the presence of Erebia gorge (Hubner, [1804]) has been reconfirmed in the Pollino massif (Calabria, Italy). In July 2019, two specimens (1 male and 1 female) were captured in the zone of Monte Pollino cliffs on the east face of the massif at a height of 1990 m. Given the isolation of the population at the southernmost limit of the species' range, and the fact that this population is seriously threatened by global climate change, it would be of great value to conduct an exhaustive study of the distribution of the species throughout Pollino and of the genetic characteristics of this local population that could differ substantially from other Italian and European populations
Località di raccolta inedite di Satyrium w-album (Knoch, 1782) in Toscana
Full text linkThe new records relate to twenty-two localities, eight of which are in the province of Siena, four in the province of Grosseto, three of Arezzo and Florence, two of Massa Carrara, one of Livorno and one of Pisa. The localities are located inside or at the edge of wooded areas, from a minimum of 45 m to a maximum of 915 m above sea level. The flight period is between the second fortnight of May and the first fortnight of August, with a maximum of observations in June (59,1% of cases). Since it is an uncommon species that lives in habitat in progressive alteration by humans, S. w-album is
believed to be threatened in Tuscany
