Comparative ecology of two specialist bees: Dasypoda visnaga Rossi, 1790 and Dasypoda maura Pérez, 1895 (Hymenoptera, Melittidae)

Many wild bee species are declining globally. To design efficient mitigation strategies to slow down or reverse these trends, we urgently need better understand their basic ecological requirements. In this context, studied two specialist for which data scarce: Dasypoda visnaga and maura . We provide the first-time detailed information on phenologies, morphological traits, floral preferences, nesting behaviours based historical new samples from Morocco. The flight season of both extends late spring summer but D. emerges earlier than Though show different palynological analyses that females collect almost exclusively pollen Scolymus sp. (Asteraceae). Concerning behaviour, seems be more gregarious Both build nests in sandy soil can reach a depth 80 cm. These observations differences between minor with regards habitat
