Rozen, Jerome G., Jr. (Jerome George), 1928-Pisanty, Gideon.Trunz, Vincent.Bénon, Dimitri.Dorchin, Achik.Praz, Christophe J.2015-04-222015-04-222015-04-21http://hdl.handle.net/2246/658518 pages : illustrations (some color) ; 26 cm.Herein we present information on the nesting behavior of Ochreriades fasciatus (Friese) found occupying beetle galleries in dead trunks and branches of certain trees and shrubs in Israel. We also describe the pre- and postdefecating larvae thereby making known the mature larva for this uncommon Old World genus. Females of O. fasciatus build linear nests in existing burrows in dead wood; depending on the length of the burrow, 1-5 cells are placed in one nest. The cell partitions are made of hardened mud, while the nest plug consists of pebbles fixed together with mud. Ochreriades fasciatus is oligolectic on Lamiaceae and probably strongly associated with the two related genera Ballota and Moluccella. It is hoped that information concerning its nesting biology, host-plant relationships, as well as larval development and anatomy will eventually prove valuable in determining the phylogenetic position of this genus relative to other megachiline bees.en-USOchreriades fasciatus.Nests.Larvae.Host plants.Lamiaceae.Megachilidae.Phylogeny.Bees.Israel.
