The large genus Calliopsis (Andrenidae, Panurginae) is composed of ten subgenera with polylectic and presumably oligolectic species. These categories have been mainly developed from floral visits of female bees collecting pollen. In the present study, pollen analyses of nest provisions and scopal loads from museum specimens of the monotypic subgenus Ceroliopoeum were carried out to assess its degree of specialization to pollen host-plants. Despite the great variability of floral resources close… 
Pollen Resources Stored in Nests of Wild Bees Xylocopa ciliata Burmeister and Megachile pusilla Pérez (Hymenoptera: Anthophila) in a Temperate Grassland-Forest Matrix
TLDR
Pollen analysis was employed to study the diet composition of two wild bees in a patch of temperate grassland invaded by exotic plants to help explain its naturalization in the New World and other areas of the Old World.
Assessment of the pollen diet in a wood-dwelling augochlorine bee (Halictidae) using different approaches
TLDR
The diet of the augochlorine bee Augochlora amphitrite is characterized using nest and intra-nest pollen analyses and bee flower visitation and a novel approach, the index of relative importance (IRI), a method that combines pollen counts, pollen volume, and frequency of pollen occurrence.
Are Stingless Bees a Broadly Polylectic Group? An Empirical Study of the Adjustments Required for an Improved Assessment of Pollen Diet in Bees
TLDR
Simple values were proposed to assess pollen diet of generalist bees: the maximum number of foraging items per nest and the maximum percentage value of foraged versus available items (adjusted) belong to a wider range of values that can be recognized as degrees of polylecty, allowing for a more precise identification.
Floral morphometric analysis of Prosopis affinis Spreng. (Fabaceae) suggests flexibility of the reproductive system in isolated populations within the Brazilian Pampa
TLDR
The pollen/ovule ratio and the outcrossing index suggest flexibility of the reproductive system, with values intermediary between facultative autogamy and xenogamy.

TLDR
Pollen analysis proved that the ground-nesting bee Eremapis parvula is a specialist bee of Prosopis, and the narrow oligolecty category for E. parvulas is supported here.
Pollen hosts of western palaearctic bees of the genus Colletes (Hymenoptera: Colletidae) : the Asteraceae paradox
TLDR
The pattern of use of Asteroideae pollen by the Colletes bees supports recent findings that this pollen possesses unfavourable or protective properties, which render its digestion difficult, and suggests that bees need physiological adaptations to successfully utilize it.
The Solitary Bee Calliopsis zebrata: Biological and Distributional Notes and Description of Its Larva (Hymenoptera: Andrenidae: Panurginae)
TLDR
The first SEM pictures of any panurgine larva reveal unexpected details of integumental sculpturing, and shows that they are essentially identical and differ little from those of other Macronomadopsis and even Nomadopsis s.l.
Floral resource utilization by solitary bees (Hymenoptera: Apoidea) and exploitation of their stored foods by natural enemies.
TLDR
The evolution of resource specialization (including parasitism) in bees presents excellent opportunities to investigate phenotypic mechanisms responsible for evolutionary change.
Molecular phylogeny and diversification history of Prosopis (Fabaceae: Mimosoideae)
TLDR
A combined approach including molecular phylogeny, molecular dating, and character optimization analysis was applied to study Prosopis diversification and evolution, suggesting that prosopis is not a natural group.

TLDR
This paper provides the first quantification of pollination effectiveness and pollination efficiency of several groups of insects that forage on P. velutina in the Sonoran Desert near Tucson, Arizona, and discusses in regard to interactions between floral development and insect behaviour.

TLDR
Calliopsis (Hypomacrotera) persimilis is a solitary, ground-nesting bee whose natural history makes it particularly convenient for studies of investment patterns and foraging behavior, and results support the use of adult dry body weight ratios in the estimation of cost ratios.
