description Backgrounds and aims: To detect floral interactions between species of family Amaryllidaceae and bees (Hymenoptera: Apoidea: Anthophila), the presence of pollen from wild and cultivated Amaryllidaceae in the nests of wild non-Apis bees collected in three Argentine eco-regions (Pampa, Pampa-Espinal and Chaco) was investigated.  M&M: A total of 500 microscopic slides of pollen and honey from 369 nests of 25 bee species were analyzed. The identification was made by comparing the pollen from nests with the reference pollen obtained from the flowers collected in the studied areas. The flower phenology of the wild species and floral visitation with catching of bee individuals were also recorded. Results: A total of 6 pollen types belonging to Amaryllidaceae were identified in the pollen diet of only five of the 25 bee species analyzed: Xylocopa artifex (Hippeastrum types 1 and 2 and Crinum), Megachile jenseni (Allium triquetrum and Zephyrantes minima), Xylocopa augusti (Crinum), Xylocopa ciliata (Zephyrantes minima) and Ceratina rupestris (Nothoscordum gracile). Among wild Amaryllidaceae, two different flowering patterns were observed: 1) in the wet periods of winter-spring and/or summer-autumn, and 2) very synchronous and ephemeral, triggered by the rains in summer-autumn.  Conclusions: The five bee species presenting Amaryllidaceae pollen in their nests and most bees collected on flowers were polylectic (generalized pollen usage) from Apidae and Halictidae families. The absence of Amaryllidaceae in samples from the Chaco eco-region may be due to its very low flower availability due to the poor species richness and ephemeral flowering pattern. More research is needed to deeply study the floral associations between bees and Amaryllidaceae in Argentina, and it is expected that there will be a higher number of bee species with pollen specialization (oligolecty) towards particular clades of this lineage of monocots.

Introducción y objetivos: A fin de detectar patrones de asociaciones entre Amaryllidaceae y abejas (Hymenoptera: Apoidea: Anthophila), se investigó la presencia de polen de Amaryllidaceae silvestres y cultivadas en nidos de abejas silvestres no Apis colectados en tres ecorregiones de Argentina (Pampa, Pampa-Espinal y Chaco).  M&M: Se analizaron un total de 500 preparados microscópicos de polen y miel de 369 nidos de 25 especies. La identificación fue realizada por comparación con polen de referencia de flores recolectadas en los sitios estudiados. También se registraron la fenología floral de las especies silvestres y visitas florales con captura de individuos de abejas.  Resultados: Se identificaron 6 tipos polínicos de Amaryllidaceae en la dieta polínica de sólo cinco de 25 especies de abejas analizadas: Xylocopa artifex (Hippeastrum tipos 1 y 2 y Crinum), Megachile jenseni (Allium triquetrum y Zephyrantes minima), Xylocopa augusti (Crinum), Xylocopa ciliata (Zephyrantes minima) y Ceratina rupestris (Nothoscordum gracile). Entre las Amaryllidaceae silvestres se observaron dos patrones de floración marcadamente diferentes: 1) en épocas húmedas invierno-primaverales y/o estivo-otoñales, y 2) sincronizadas y efímeras, desencadenadas por las lluvias estivo-otoñales.  Conclusiones: Las cinco especies de abejas con polen de Amaryllidaceae en sus nidos y la gran mayoría de las recolectadas en las flores fueron polilécticas (uso de polen generalizado) de las familias Apidae y Halictidae. La ausencia de Amaryllidaceae en muestras de la eco-región chaqueña puede ser debido a su muy reducida oferta floral dada por la baja riqueza de especies y patrón efímero de floración. Existe mucho por investigar en cuanto a las asociaciones florales entre abejas y Amaryllidaceae en Argentina, y se espera que hayan más especies de abejas con especialización por polen (oligolectia) hacia clados particulares de este linaje de monocotiledóneas.
