ItemThe bee Svastra sabinensis : nesting biology, mature oocyte, postdefecating larva, and association with Triepeolus penicilliferus (Apidae, Apinae, Eucerini and Nomadinae, Epeolini). (American Museum novitates, no. 3850)(American Museum of Natural History., 2016-02-18) Rozen, Jerome G., Jr. (Jerome George), 1928-Information on the nesting biology of the large, ground-nesting, communal eucerine Svastra (Epimelissodes) sabinensis sabinensis (Cockerell) from Arizona is added to a previous account (Rozen, 1983). Details of nest size, location, depth, and structure are reported. Mature oocytes dissected from females are illustrated and described. Further information on its cocoon is presented and interpreted with respect to how it functions. The postdefecating larva is described and compared with that of S. o. obliqua (Say), the only other Svastra larva described to date. The association of this bee with Triepeolus penicilliferus (Brues) is further confirmed with the recovery of an immature larva of this cleptoparasite from one of the nest cells.

American Museum novitates ; no. 3108(New York, N.Y. : American Museum of Natural History, 1994) Rozen, Jerome G., Jr. (Jerome George), 1928- ItemBiology and immature stages of Macropis nuda, including comparisons to related bees (Apoidea, Melittidae). American Museum novitates ; no. 2702(New York, N.Y. : American Museum of Natural History, 1980) Rozen, Jerome G., Jr. (Jerome George), 1928-; Jacobson, Ned Robert."The present study treats the following topics pertaining to the life history of the solitary bee Macropis nuda (Provancher), the first North American species of the genus to be found nesting: Nest site localities, nest description, nest construction, flower relationships, provisioning, development (including description of egg), larval feeding habits, cocoon construction, defecating pattern, sleeping habits of adults, mating behavior, daily and seasonal activity patterns, and parasitism and predation. Comparisons of these features are made with several Palearctic species. The life history of this species agrees with accounts of European species in the literature. Several newly discovered characteristics of the cocoon of M. nuda correspond well with similar features in other Macropis and Melitta, but not with Meganomia and Ctenoplectra of South Africa. The last larval instar and the pupa are described taxonomically and agree closely with similar stages of other members of the genus"--p. .

American Museum novitates ; no. 2457(New York, N.Y. : American Museum of Natural History, 1971) Rozen, Jerome G., Jr. (Jerome George), 1928-"The present paper, which is intended to shed light on the phylogeny and systematics of the bees belonging to the subfamily Panurginae, treats the biology and immature stages of three genera found in Morocco: Panurgus, Panurginus, and Melitturga. (1) Observations on the environment of the nesting site, flower relationships, nest structure, provisioning, oviposition, development, adult activity, and parasitism by cuckoo bees are presented; comparisons are made with panurgines from other parts of the world. (2) The mature larvae of the three genera are described and contrasted with those of other panurgines. (3) Pupae of panurgus and panurginus are described.

American Museum novitates ; no. 2331(New York, N.Y. : American Museum of Natural History, 1968) Rozen, Jerome G., Jr. (Jerome George), 1928- ItemBiology and immature stages of the bee genus Meganomia (Hymenoptera, Melittidae). American Museum novitates ; no. 2630(New York, N.Y. : American Museum of Natural History, 1977) Rozen, Jerome G., Jr. (Jerome George), 1928-"The hibernating, postdefecating larva and pupa of Meganomia binghami (Cockerell) are described and compared with similar stages of other melittid bees. Biological information on this species and on an undescribed species of Meganomia includes the following information: nest ecology, nest configuration and structure, provisioning, development, number of generations a year, mating, sound production and daily activity of adults. The placement of the genus in the Melittidae cannot be evaluated on the basis of larvae because the numerous similarities shared by Meganomia, Melitta, and Macropis are symplesiomorphic. However, there are no larval characteristics that would exclude Meganomia from the family. Cladistic analysis of features of the mature larva indicates that Meganomia is a sister group to all other melittids whose immaturites are known"--p. . ItemBiology and immature stages of the bee Nomioides patruelis (Halictidae, Halictinae, Nomioidini) and of its cleptoparasite, Chiasmognathus pashupati (Apidae, Nomadinae, Ammobatini), with a preliminary phylogeny of the Halictidae based on mature larvae (Apoidea) ; American Museum novitates, no. 3604(New York, NY : American Museum of Natural History, 2008) Rozen, Jerome G., Jr. (Jerome George), 1928-Mature larvae and pupae of Nomioides patruelis Cockerell and of its cleptoparasite, Chiasmognathus pashupati Engel, collected from the nesting site near Karachi, Pakistan, are described, providing the first account of the immature stages of the respective genera and the first such account for any Nomioidini. An egg of N. patruelis is also described. An analysis, based on both halictid specimens and descriptions from the literature, reveals that the three subfamilies (Rophitinae, Nomiinae, and Halictinae) of Halictidae can be distinguished on the basis of their mature larvae. A key is provided for their identification. Mature larvae of the tribes of the Halictinae are so similar they cannot be distinguished at present, although studies of additional representatives may yield diagnostic features particularly concerning mandibular anatomy and perhaps body size. Features of the mature larvae when mapped onto a phylogeny of the Halictidae (Pesenko, 2000) provide a hypothesis for the sequence of anatomical changes in the evolution of mature larvae. Observations during excavation of the nesting site provided detailed, if fragmentary, information concerning nest architecture, provisioning, voltinism, and nest parasites of Nomioides paturelis. These are discussed in relation to information concerning other species of Nomioidini from the literature. Chiasmognathus pashupati, like its host, is probably multivoltine. The anatomy of the mature larva is similar to that of other Nomadinae, especially that of Ammobatini; however, the pupa is distinct from those of other known Ammobatini. The mature oocyte of the related C. orientanus (Warncke) from Turkey, described previously (Rozen and Özbek, 2003), is likely to resemble that of C. pashupati. ItemBiology and immature stages of the bee tribe Tetrapediini (Hymenoptera, Apidae). American Museum novitates ; no. 3377(New York, NY : American Museum of Natural History, 2002) Santos, Isabel Alves dos.; Melo, Gabriel A. R.; Rozen, Jerome G., Jr. (Jerome George), 1928-Tetrapedia diversipes Klug is herein reported for the first time to be the host of the cleptoparasite Coelioxoides waltheriae Ducke. Because these two genera had been previously recognized as sister taxa (A. Roig-Alsina. 1990. Coelioxoides Cresson, a parasitic genus of Tetrapediini (Hymenoptera: Apoidea). Journal of the Kansas Entomological Society 63: 279-287), the authors wished to learn to what extent biological information and immature stages reflected this relationship. Tetrapedia diversipes normally nests in holes in wood such as old beetle burrows, and it was induced to use trap nests for this study. Many aspects of the nesting behavior of females of this species are described, including the following: diurnal flight period; sleeping habits; nest structure; nest provisioning; egg placement; and sequence of nest construction, provisioning, and oviposition. Eggs produced by this species are categorized as "giant" (K. Iwata and S.F. Sakagami. 1966. Gigantism and dwarfism in bee eggs in relation to the mode of life, with notes on the number of ovarioles. Japanese Journal of Ecology 16: 4-16). Its first instar was discovered to be pharate within the chorion while the following four instars actively feed. Defecation starts early in the last larval stadium. Females use floral oils both in nest construction and in provisioning, and they carry pollen, oil, and soil with their scopae. The biology of T. diversipes was compared with that of other species in the genus and then compared with that of other apines that are known to nest in preformed cavities and that provision nests with pollen and floral oils. The host-nest searching behavior of Coelioxoides waltheriae is described. The cleptoparasite introduces its egg into the closed cell of the host shortly after cell closure. This egg is characterized as "small" (Iwata and Sakagami, ibid.) and has a very short incubation period. The highly modified first instar immediately feeds on the host egg and grows remarkably fast on the host yolk. This species has only four instars. Rates of development of the host and cleptoparasite are compared. Both have four ovarioles per ovary. Eggs, first instars, last larval instars, and pupae of host and cleptoparasite are taxonomically described and compared. In conclusion, the immatures of Coelioxoides and Tetrapedia are quite distinct from those of other known apids. While these two genera are probably sister genera based on the similarities identified by Roig-Alsina (op. cit.) and by this study, they are quite different from one another based on features of the eggs, first instars, and pupae. ItemBiology and immature stages of the panurgine bee genera Hypomacrotera and Psaenythia (Hymenoptera, Apoidea). American Museum novitates ; no. 2416(New York, N.Y. : American Museum of Natural History, 1970) Rozen, Jerome G., Jr. (Jerome George), 1928- ItemBiology and larvae of the cleptoparasitic bee Townsendiella pulchra and nesting biology of its host Hesperapis larreae (Hymenoptera, Apoidea). American Museum novitates ; no. 3005(New York, N.Y. : American Museum of Natural History, 1991) Rozen, Jerome G., Jr. (Jerome George), 1928-; McGinley, Ronald J. ItemBiology and morphology of the immature stages of the cleptoparasitic bee Coelioxys chichimeca (Hymenoptera, Apoidea, Megachilidae). (American Museum novitates, no. 3679)(New York, NY : American Museum of Natural History., 2010) Rozen, Jerome G., Jr. (Jerome George), 1928-; Vinson, S. Bradleigh, 1938-; Coville, Rollin E.; Frankie, G. W.Herein we investigate the behavior and anatomy of all larval instars of the cleptoparasitic bee, Coelioxys (Cyrtocoelioxys) chichimeca Cresson. The species is found in Central America with its host, Centris (Heterocentris) bicornuta Mocsáry, one of the cavity-nesting members of the genus. The egg/mature oocyte of C. chichimeca, unusually small (like known eggs of other Coelioxys), is described, as is egg placement in the wall of the brood chamber. The anatomy and behavior of each of the five larval instars is described. The first instar develops within the egg chorion, from which the second instar emerges. The second and third instars apparently normally remain attached by their posterior ends either to the egg chorion or to the place where the egg had been attached to the cell wall. The second instar possesses an array of large spines on the outer surface of each mandible thought to rupture the thick chorion, thus allowing eclosion. Both second and third instars have modified head capsules and mandibles enabling them to attack host immatures. Both instars possess an extremely large pair of spiracles on the eighth abdominal segment and lesser-enlarged spiracles on the two preceding abdominal segments as well as enlarged internal lateral tracheal trunks. These modifications are likely related to the need for the larva to acquire air from the substrate while the body is submerged in nectar. Fourth and fifth instars, no longer attached to the substrate, assume the morphological attributes and behavior of normal provisions-consuming megachilid larvae. The last larval instar defecates and afterwards spins a cocoon bearing a conspicuous nipple. A male pupa is also illustrated and described.

American Museum novitates ; no. 3308(New York, NY : American Museum of Natural History, 2000) Michelette, Elen R. F.; Camargo, João Maria Franco de.; Rozen, Jerome G., Jr. (Jerome George), 1928-Data are presented on the nesting and phenology of Canephorula apiformis Friese (Apidae: Eucerini), a monotypic genus of bees endemic to the arid and semiarid regions of the Argentinian northwest. Aggregations of nests are found in the ground where the surface is horizontal and frequently exposed to the sun. The brood cells, 5-6 cells per nest, are at an approximate depth of 20 cm. Floral hosts include Prosopis strombulifera (Fabaceae), Atamisquea emarginata (Capparidaceae), Larrea divaricata (Zygophyllaceae), and Tessaria absinthioides (Asteraceae) and are visited mainly between 10:00 and 14:00 hr. Adults and immature stages of Melectoides bellus (Jörgensen) (Apidae: Isepeolini) were found in the nests, the first association for this cleptoparasitic tribe with any host other than the genus Colletes. Canephorula apiformis may have two generations per year while the voltinism of its cleptoparasite is uncertain. The mature larvae of both host and cleptoparasite are described for the first time and compared with known larvae of their respective tribes. Cocoons of the two species are also described, illustrated, and compared to those of related taxa. ItemBiology of the bee genus Conanthalictus (Halictidae, Dufoureinae). American Museum novitates ; no. 2602(New York, N.Y. : American Museum of Natural History, 1976) Rozen, Jerome G., Jr. (Jerome George), 1928-; McGinley, Ronald J."The following details of the nesting biology of Conanthalictus (Sphecodosoma) dicksoni Timberlake and C.(C.) conanthi (Cockerell) are given and where possible are compared and contrasted with the biologies of Dufourea and the other dufoureines: choice of nesting site, number of females to a nest, nest description, pollen plant preference, provisioning habits, appearance of eggs and larvae, feeding activities of larvae, cocoon construction and appearance, number of generations per year, adult activities, and nest associates. The Dufoureinae appears to be a homogeneous and distinctive taxon in terms of its nesting habits"--P. . ItemBiology of the bee Hoplitis (Hoplitis) monstrabilis Tkalců and descriptions of its egg and larva (Megachilidae, Megachilinae, Osmiini) (American Museum novitates, no. 3645)(2009) Rozen, Jerome G., Jr. (Jerome George), 1928-; Özbek, Hikmet.; Ascher, John S.; Rightmyer, Molly G.Herein we describe the nesting biology of the solitary ground-nesting bee Hoplitis (Hoplitis) monstrabilis Tkalců from eastern Turkey. Its shallow nests in the ground differ from the known nests of members of subgenus Hoplitis, most of which make mortar and pebble nests either on the exposed surfaces of rocks or within stems or other cavities. Cells are not lined with flower petals or other vegetative tissue, as expected for subgenus Hoplitis, but unlike other ground-nesting species of Hoplitis belonging to other subgenera such as Anthocopa. The egg of this bee is also described and illustrated, as is the fifth (last) larval instar. ItemBiology of the cleptoparasitic bee Mesoplia sapphirina (Ericrocidini) and its host Centris flavofasciata (Centridini) (Apidae, Apinae). (American Museum novitates, no. 3723)(American Museum of Natural History., 2011-10-15) Rozen, Jerome G., Jr. (Jerome George), 1928-; Vinson, S. Bradleigh, 1938-; Coville, Rollin E.; Frankie, G. W.; Melo, Gabriel A. R.; Rocha-Filho, Léo C.This paper investigates the bionomics of the cleptoparasitic bee Mesoplia sapphirina Melo and Rocha-Filho, sp. nov. (described in the appendix), and of its ground-nesting host Centris flavofasciata Friese found along the Pacific coast of Guanacaste Province, Costa Rica. We explore the host-nest searching behavior, egg deposition, and hospicidal behavior of M. sapphirina. Anatomical accounts of its egg, first, second, and fifth larval instars are presented and compared with published descriptions of other ericrocidine taxa. Nests of the host bee as well as its egg and method of eclosion are also described.
