Abstract
We described the nesting behavior and ecology of Diadasina riparia, from an urban dry forest fragment. The nests of D. riparia were shallow with circular entrance, closed by a mud plug, from which a straight vertical tunnel ending in one or more brood cells. Most females need one day for construction and provisioning the nest. The natural enemies were flies of Anthrax genus, the cleptoparasitic bees Leiopodus trochantericus, and Mutillidae wasp. The feature about the life history, nest architecture, materials used, pollen provisions behavior and associated organisms of this species allow the comparison with other emphorines species.
Highlights
Bees are the most effective pollinators of nature and ensure the maintenance of crops and wild plants (Nabhan & Buchmann, 1997; Klein et al, 2007)
We present data and observations on the nesting biology of D. riparia, a solitary bee species with distribution restricted to South America (Moure & Melo, 2012)
Our study presented the first record on the nesting biology of Diadasina riparia
Summary
Bees are the most effective pollinators of nature and ensure the maintenance of crops and wild plants (Nabhan & Buchmann, 1997; Klein et al, 2007). Solitary bees comprise 85% of known species, and among them, females make their own nest, supply them with food, and die before the generation emerges (Batra, 1984; Michener, 2007). These bees can use different substrates for nesting, and the ground is the most widespread among all groups (Michener, 1964; 2007; Harmon-Threatt, 2020). This scarcity of studies is mainly due to the difficulty of finding nests in the field
