In the Marches it is distributed almost exclusively in the highlands and on the lower slopes of mountainous areas. According to the available data, B. /I/If/J_)'JDIlS is present in 25 out of the 130 UTM grid squares which cover the entire Marches region (19.2% of the sample). Most records refer to altitudes between 400 and 800 m asl; reproductive sites include streams (19 sites, 44% of the sample), puddles (11 — 25.5%), drinking troughs (9 — 21%) and ponds (4 — 9.3%). The reproductive season starts in April/May and may continue until October. The species, listed in Annexes H and IV of the Habitat Directive and in the Annex II of the Berna Convention, is very sparsely distributed in the region, with small isolated populations. B. pat/Jypi/5 is threatened especially by man—made modification undertaken in the management and use of the territory: the main threats encountered in the Marches are the destruction of reproductive habitats, spring capping and drought. These problems call for urgent actions to plan an interregional/national program of conservation strategies and to increase long—term monitoring projects and the availability of breeding sites. INTRODUZIONE Bombimzpac/aypzzs (Bonaparte, 1838) e una specie endemica dell’Italia penin— sulare solo recenternente elevata a tango specificoz fino a qualche anno fa, infat— ti, era considerata una sottospecie di Bombimz wzriegzzm (Linnaeus, 175 8). Il pas- saggio sisternatico e dovuto sia a ricerche di carattere biochimico e genetico (Nascetti et al., 1982; Fromhage et al.,,, 2004), sia a differenze morfologiche e cromatiche tra i due taxa (Vandoni, 1914; Vaccaneo, 1931; Lanza e Corti, 1993). L’Ululone appenninico si rinviene in modo non uniforme lungo la dorsale appenninica, dalla Liguria occidentale alla Calabria (Guarino et al., 2006), men— tre per B. wzriegzztzz la distribuzione in Italia si limita all’area geografica a nord del fiume Po, dalla Lombardia al Friuli-Venezia Giulia (Bressi e Barbieri, 2006).
