Biology and Immature Stages of the Bee Tribe Tetrapediini (Hymenoptera: Apidae)
TLDR
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.
Nesting Biologies and Immature Stages of the Tapinotaspidine Bee Genera Monoeca and Lanthanomelissa and of Their Osirine Cleptoparasites Protosiris and Parepeolus (Hymenoptera: Apidae: Apinae)
Abstract The nesting biologies of Monoeca haemorrhoidalis (Smith) and Lanthanomelissa betinae Urban (Tapinotaspidini) are described from southeastern Brazil. Both are ground nesting; the nests of the…
Nesting biology of diphaglossine bees (Hymenoptera, Colletidae). American Museum novitates ; no. 2786
Nesting and Developmental Biology of the Cleptoparasitic Bee Stelis ater (Anthidiini) and Its Host, Osmia chalybea (Osmiini) (Hymenoptera: Megachilidae)
TLDR
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.
Investigations on the Biologies and Immature Stages of the Cleptoparasitic Bee Genera Radoszkowskiana and Coelioxys and Their Megachile Hosts (Hymenoptera: Apoidea: Megachilidae: Megachilini)
TLDR
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.
Eggs, Ovariole Numbers, and Modes of Parasitism of Cleptoparasitic Bees, with Emphasis on Neotropical Species (Hymenoptera: Apoidea)
TLDR
The unusual modified shapes of mature oocytes/eggs and the thick chorions of cleptoparasites that oviposit in open host cells are attributed to ways of protecting the eggs from discovery and damage by returning host females.
Nesting biology and immature stages of the bees Centris caesalpiniae, C. pallida, and the cleptoparasite Ericrocis lata (Hymenoptera: Apoidea: Anthophoridae).
TLDR
Nest site requirements, nest architecture and structure, cocoon constructions, larval defecation patterns, provisioning, some aspects of development and adult emergence, and nest parasitism are described and significant interspecific differences pointed out.
Biology of the Cleptoparasitic Bee Mesoplia sapphirina (Ericrocidini) and Its Host Centris flavofasciata (Centridini) (Apidae: Apinae)
TLDR
The host-nest searching behavior, egg deposition, and hospicidal behavior of M. sapphirina is explored and Anatomical accounts of its egg, first, second, and fifth larval instars are presented and compared with published descriptions of other ericrocidine taxa.
