We present for the first time, a compilation of distributional and phenological information relating to all species of the family Zygaenidae Latreille, 1809 in the province of Avila (Spain). In total, we studied 691 specimens of 19 taxa: 12 Zygaeninae, 1 Chalcosiinae and 6 Procridinae. We also report on the presence of Zygaena fausta (Linnaeus, 1767), Zygaena lavandulae (Esper, 1783), Zygaena lonicerae (Sheven, 1777), Jordanita subsolana (Staudinger, 1862) and Jordanita budensis (Speyer & Speyer, 1958), as new species for Avila province. Information about distribution and rarity of all species in the study area is provided. We include maps in 10 X 10 km UTM squares for all species, that extend the distribution of most of them wimin Spain.

We study the geographic distribution of Thecla betulae (Linnaeus, 1758) in the Central Mountain System, one of the less recorded butterflies in the centre of the Iberian Peninsula. We also analyse the scarce data in literature, and expand substantially its distribution area from 4 to 36 X 10 km UTM grids, giving unpublished information for 32 new grids. We add new recent data for the provinces of Avila and Madrid (Spain); we confirm the presence of the species in the province of Caceres (Spain), after four decades without any record; we give the first data of the species from the province of Salamanca (Spain), and we report new records from the Centre of Portugal. The altitudinal range of these populations is 550 to 1245 m. We provide data on its biology, habitat and foodplants. In the study area the larvae feed on Prunus spinosa, P. domestica, P. insititia and P. avium (Rosaceae). Finally, we analyse threats to the species and propose some conservation measures. © SHILAP Revista de lepidopterología.

We provide new data on the biology and ecology of the rare skipper Pyrgus cacaliae (Rambur, 1839) in the Iberian Peninsula: Geum montanum L. (Rosaceae) is cited as foodplant for the first time and Cotesia sp. (Hymenoptera) as a larval parasitoid. Morphological details studied with the scanning electron microscope are given for the egg, last instar larvae and pupae. The geographic distribution of P. cacaliae and G. montanum in the Iberian Peninsula are highly coincident, suggesting that this is the main foodplant in the Pyrenees. The possibility that the butterfly could be found in the Cantabrian Mountains is suggested and the conservation status of the butterfly in the study area is discussed.
