The reproductive behavior of
Anthidium maculosum (Hymenoptera: Megachilidae) and the evolutionary significance of multiple copulations by females.
Most of the bees collected in this study were megachilids, including Osmia lignaria, a native bee that builds nest partitions from macerated mud (Bosch, 1994); Anthidium maculosum, a small native bee that lines its nest cells with plant trichomes (Alcock et al., 1977); Megachile apicalis, an introduced European species that builds cell partitions with fragments of leaves or flowers (Barthell et al., 2002); and Hoplitis albifrons maura, a native bee that builds partitions using macerated leaves and coarse mud (Michener, 1947).
Most species for which more than 10 individuals were collected in 2010 showed a significant effect of month on abundance by post (permutational ANOVA; Anthidium maculosum, P = 0.2245, Apoidea, P = 0.0002, Eumeninae, P < 0.00001, Euodynerus foraminatus, P = 0.0036; Megachile apicalis, P = 0.019; Osmia lignaria, P < 0.00001; Trypoxylon tridentatum, P = 0.091).
Some exotic bee species also exhibit aggressive flower-patch defending behaviour towards other flower-visiting insects, as is the case with males of the European Wool-Carder bee
Anthidium manicatum, which has become established in many countries far beyond its native range, most recently in New Zealand (Donovan 2007).
Two of the most common visitors are the "leaf-cutter" or "wool carder" bees from the genus
Anthidium. These names result from their practice of lining their nest cavities in the soil or within shrub stems with shredded leaves.

Anthidium manicatum, Osmia sp., Megachile sp., and Halictus sp.
Apis mellifera was responsible for 5 1.5% of all flowers visited, followed by Bombus terrestris (17.5%),
Anthidium breviusculum (6.9%), and Ceratina cyanea + mocsaryi (6.1%).
Its stronger weighting results in the monophyly of the genus
Anthidium, which is widely accepted by several authors (Pasteels 1969, Michener and Griswold 1994).

filipes belong to 34 species of the bee genus Osmia (Megachilidae), with additional species in the genera

In 2010 with entomological nets, we collected 32 hymenopteran species on weeds, and 22 (68.75%) of these were collected from "La Concepcion" orchard, where
