In August some adults stopped feeding and in diapause condition sheltered under stones and among leaves or seed capsules of plants where they had fed. ![]() We found four significant correlations between the different food sources observed. There was no statistical difference between the number of adults containing remains of aphids, fungal spores, and pollens. septempunctata adults showed that pre-diapause diet consisted of aphids, pollen of Compositae and Umbelliferae, and spores of fungi (e.g., Alternaria spp., Cladosporium spp.). were major food sources at 1800 m altitude. Echinops ritro L., Eryngium amethystinum L., Carlina acaulis L., Cirsium eriophorum (L.), Galium verum L. Haymaking forces ladybirds to move towards higher locations in search of food. At "Pian Grande" location, adults were found in crop fields (lentil, mustard) and wild pastures (cornflower, gentian) mating and feeding on aphids, pollens, nectar and fungal spores. broom aphid) and pollens of several plants (e.g., Laserpitium garganicum Tem., Centaurea rupestris L., Cachrys ferulacea L. After aggregation, the hungry adults disperse to flowering plants at lower elevations where they feed on 8 aphid species (e.g. We investigated the gut content of adults from this location. septempunctata was found together with Vibidia duodecimguttata (Poda) and Leptinotarsa decemlineata (Say). Due to the warming of the sun they sink to a depth of 5-6 cm, so that they remain trapped in the frozen snow during the night. Vettore), the adults, exhausted by the long flight, usually remain motionless on the snow. When reaching high altitude locations still covered with snow (Lake Pilato, 1940 m, on Mt. ![]() Vettore (2478 m) we witnessed a "shower" of ladybirds, some of which hid in the turf. When the sunny weather returns again, due to the mistral (north-western wind), the adults continue the flight in swarms to mountain areas. During this migration, strong south-western storms often force the ladybirds to shelter in urban habitats. However, most of the adults migrate to mountain pastures to find different food sources. on sugarbeet), and also on pollens of wild plants such as Carduus nutans L., and fungi spores. Some of them remain in the valley while some leave the cereals and fly to other crops, where they feed both on 15 aphid species (e.g., Aphis gossypii Glov. In the second half of June, newly emerged adults have various migratory behaviours. The species reproduces in spring feeding mostly on aphids infesting Graminaceae. adults was carried out from 1998 to 2002 in the Tiber Valley, in the Botanical Garden of Perugia University, and in the Sibillini Mountains National Park (Central Italy).
