ABSTRACT Peltogyne chrysopis is an arboreal legume endemic to the Atlantic Forest and known only from the state of Bahia, Brazil. Focal observations were made of anthesis, pollen availability, stigma receptivity, nectar production, and the presence of osmophores and UV-reflective pigments for the species. Floral visitors were also observed and classified based on the timing and frequency of their visits and their foraging behavior. The breeding system was inferred from the pollen-ovule ratio and pollen tube growth after pollination treatments. Peltogyne chrysopis was found to be melittophilous, with anthesis occurring from 02h00min to 05h00min, and protogynous and xenogamous, with flower scent emission and pollen release before sunrise.

A study of the life history of the solitary bee Monoeca xanthopyga, was conducted at the Araucária Plateau, at the state of Rio Grande do Sul. The study focused the seasonality, sexual behavior, females activity during nest building, the exploited plant resources and the associated parasitoids. Three nest aggregations of M. xanthopyga built in clay soil with few plant cover or none at all, were studied on the Parque Nacional dos Aparados da Serra, located in Cambará do Sul, Rio Grande do Sul State. The nests were randomly distributed in areas up to eight square meters in size and reach a maximum density of 57 nests per square meter. The only one generation occurred from January to April. The immature stayed in diapausa in the prepupa stage during eight to... |
