First Observations on Nesting and Immatures of the Bee GenusAncyla(Apoidea: Apidae: Apinae: Ancylaini)

Abstract

Herein we present information on the nest architecture and nesting biology primarily of Ancyla asiatica Friese and, to a lesser extent, of A. anatolica Warncke, both found near Adana, turkey. These two ground-nesting species visit Apiaceae for mating and larval provisions, with A. asiatica going to Daucus carota and A. anatolica, to Eryngium. The cocoon of A. asiatica is described in detail as are the mature oocytes of both species and the pre-and postdefecating larvae of A. asiatica. each site was attacked by a separate, unnamed cleptoparasitic species of Ammobates (Nomadinae). The relationships of the Ancylaini to other apine tribes are discussed based on their mature larvae, and a revised tribal key to mature larvae of nonparasitic, noncorbiculate Apinae is presented.

Impact of tillage on the crop pollinating, ground-nesting bee, Peponapis pruinosa in California

“…Agricultural landscapes are often mosaics of disturbed and undisturbed ground. Within these landscapes ground nesting bees nest in natural and semi-natural areas including hedgerows (H. Sardiñas unpublished data), flower strips (N. Williams unpublished data), forest fragments (J. H. Cane, 1994), grasslands and chaparral (Sardiñas & Kremen, 2014;Straka & Rozen, 2012). They also nest in fallow and active crop fields, which experience regular disturbance in the form of tillage (Minckley et al 1994;Kim, Williams & Kremen 2006;Julier & Roulston 2009;Xie, Qiu & Chen 2013;Sardiñas et al 2015).…”

Discovery of the Bee Tribe Tarsaliini in Arabia (Hymenoptera: Apidae), with the Description of a New Species

“…The nesting biology and immature stages have been reported for two species of Ancyla (Straka and Rozen, 2012), and the species are generally considered specialists of Apiaceae and has mouthparts similar to short-tongued bees (Silveira, 1993b;Straka and Rozen, 2012 Diagnosis (modified and expanded from Engel, 2015): Bees of small to moderate size (5.5-13 mm in length); head wider than long, but face comparatively narrow, interocular distance less than compound eye length; vertex comparatively straight, not uniformly convex nor excavated between compound eyes and ocelli in facial view ( fig. 1D).…”
