| Resumo: | [EN] during a complete yearly cycle in order to describe its composition and phenology. Coloured Moericke traps filled with water were used to catch the specimens. We collected 1.080 specimens (233 males and 847 females) of 59 species, 17 genera and 6 families. The dominant species was Lasioglossum (Evylaeus) malachurum (Kirby, 1802), and the Halictidae the dominant family, both in the number of species and of individuals. There were, according to the type of cycle, several types of species: all-year-round bees [L. malachurum (Kirby) and Apis mellifera Linnaeus, 17581, bees with a long cycle (half the Halictidae plus Megachile pilidens Alfken, 1923), bees with a well-defined short cycle (three species of Andrena Fabricius, 1775 and three Megachilidae), and bees with a poorly-defined cycle. The community had two activity peaks according to the number of individuals (February-March and June-August) and one according to the number of species (July-August, the spring peak was less pronounced). The appearance of the males followed a parallel rhythm. Of the climatic factors, the mean temperature is the one which bears the biggest positive relation to the number of active species. |
