Item Biology 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.Item Immatures of rophitine bees, with notes on their nesting biology (Hymenoptera, Apoidea, Halictidae) ; American Museum novitates, no. 3609(New York, NY : American Museum of Natural History, 2008) Rozen, Jerome G., Jr. (Jerome George), 1928-; Özbek, Hikmet.This study is a taxonomic overview of the known mature larvae and pupae of the Rophitinae (Halictidae). We either describe and illustrate the mature or nearly mature larvae of the following taxa or provide references to their earlier descriptions: Dufourea holocyanea (Cockerell), D. australis australis Michener, D. mulleri (Cockerell), D. novaeangliae (Robertson), Sphecodosoma (Sphecodosoma) dicksoni (Timberlake), Protodufourea eickworti Bohart and Griswold, Xeralictus timberlakei Cockerell, Systropha planidens Giraud, Rophites (Rhophitoides) canus Eversmann, R. (Rophites) algirus trispinosus Pérez, Conanthalictus (C.) conanthi (Cockerell), and C. (Phaceliapis) bakeri Crawford. We present a key to known mature rophitine larvae. We also describe pupae of the following taxa for the first time and compare them with the pupa of S. dicksoni: D. holocyanea, D. australis australis, and R. canus. The phylogenetic relations of the treated taxa are discussed in light of larval characters, and we discuss the pupal characteristics of the entire family. We offer notes on the nesting biology of various taxa whose immatures were treated and synthesize this information with previous accounts from the literature.Item Nests, petal usage, floral preferences, and immatures of Osmia (Ozbekosmia) avosetta (Megachilidae, Megachilinae, Osmiini), including biological comparisons with other osmiine bees. (American Museum novitates, no. 3680)(New York, NY : American Museum of Natural History., 2010) Rozen, Jerome G., Jr. (Jerome George), 1928-; Özbek, Hikmet.; Ascher, John S.; Sedivy, Claudio.; Praz, Christophe J.; Monfared, Alireza.; Müller, Andreas (Biologist)Herein we describe the nests (including construction, closure, orientation, and depth of cells) of the bee Osmia (Ozbekosmia) avosetta Warncke found nesting near Antalya, Turkey, and Sepidan, Iran. Cells are unusual in that they are lined by two layers of colorful flower petals that sandwich a thin middle layer of mud. Analyses of pollen taken from scopal hairs of specimens from the Turkish site were identified as solely from Onobrychis viciifolia Scop. (Fabaceae) whereas those from the Iranian site were from a related plant, Hedysarum elymaiticum Boiss. and Hausskn. These facts coupled with analyses of scopal pollen from 11 other sites in Turkey, Jordan, and Syria strongly suggest that this bee is oligolectic with respect to the plant tribe Hedysareae. The egg and last larval instar of Osmia avosetta are described. The presence of an egg taken from a cell and provisionally identified as belonging to Sapyga pulcherrima Morawitz suggests that this cleptoparasite may have this bee as one of its hosts. In addition, we report new information on and review published accounts concerning the use of whole petals or large petal pieces in the construction of cell walls of osmiine bees. Only Osmia (Ozbekosmia) avosetta and species of Osmia (Tergosmia) have three-layered cell walls with the middle layer made of mud. Recorded also are the similarities and differences exhibited in pollen and petal preferences and nest characteristics of species in these two related subgenera.
