The in-nest biologies of Osmia lignaria propinqua Cresson, Osmia californica Cresson, and Osmia montana montana Cresson are, for the first time, described based on information obtained from within observation boxes placed in field and greenhouse environments. Cell construction, provisioning, and egg deposition are described in detail and in a comparative format. Embryogenesis, egg eclosion, molting, immature development, and cocoon construction also are described for each species based on… 

Effect of Temperature on Osmia lignaria (Hymenoptera: Megachilidae) Prepupa–Adult Development, Survival, and Emergence

There is a need for the development of regionally adapted, latitude-specific breeding populations of this outstanding orchard crop pollinator, Osmia lignaria Say, as an orchard pollinator in the United States and southern Canada.

Biology and Immature Stages of the Bee Tribe Tetrapediini (Hymenoptera: Apidae)

The immatures of Coelioxoides and Tetrapedia are quite distinct from those of other known apids and by this study are quite different from one another based on features of the eggs, first instars, and pupae.

Reproductive potential and nesting effects of Osmia rufa (syn. bicornis) female (Hymenoptera: Megachilidae)

The nesting behavior and the reproductive potential of a single O. rufa female are elucidated and the sex ratio (proportion of male and female offspring) may change during the nesting period.

Nesting and Developmental Biology of the Cleptoparasitic Bee Stelis ater (Anthidiini) and Its Host, Osmia chalybea (Osmiini) (Hymenoptera: Megachilidae)

The first account of the nesting biology of Osmia (Helicosmia) chalybea Smith and of its cleptoparasite Stelis (Stelis) ater Mitchell is provided, a newly confirmed host association.

Nesting behavior of Osmia tingitana Benoist (1969) (Hymenoptera: Megachilidae), endemic species of North Africa with first observation of its parasite Chrysura barbata Lucas (1849) (Hymenoptera: Chrysididae)

The analysis of six Osmia tingitana nests found in snail shells showed that the female selects shells belonging to the Hygromiidae family and whose diameter was between 1.8 and 3.5 cm. The nest

Biology and population structure of Osmia tricornis Latreille (Hym., Megachilidae)

Osmia tricornis Latreille is a univoltine species that in NE Spain flies from April to June and in 1990 and 1991 two populations were reared in the laboratory, showing very similar biological features to other Osmia (s. str.) Panzer species currently being used as crop pollinators.

Investigations on the Biologies and Immature Stages of the Cleptoparasitic Bee Genera Radoszkowskiana and Coelioxys and Their Megachile Hosts (Hymenoptera: Apoidea: Megachilidae: Megachilini)

The biology and immature stages (egg, mature larva, and pupa) of the cleptoparasitic bee Radoszkowskiana rufiventris (Spinola) are described for the first time based on fieldwork in Egypt over a 2-year period.

Biologia de nidificação de Anthodioctes megachiloides Holmberg (Anthidiini, Megachilidae, Apoidea)

Of 24 nests examined, 18 contained dead immature, indicating that mortality was high, and one species of Sapygidae wasp was detected as cleptoparasite of A. megachiloides.

Nesting biology and flower preferences of Megachile (Sayapis) zaptlana

Emergence patterns indicate that the species has a multivoltine life cycle without diapause and a peak emergence in the drier months from October to December, and it might be a good candidate for future use as a managed pollinator.
