Species Knowledge Review: Shrill Carder Bee Bombus Sylvarum in England and Wales
Species Knowledge Review: Shrill carder bee Bombus sylvarum in England and Wales Editors: Sam Page, Richard Comont, Sinead Lynch, and Vicky Wilkins. Bombus sylvarum, Nashenden Down nature reserve, Rochester (Kent Wildlife Trust) (Photo credit: Dave Watson) Executive summary This report aims to pull together current knowledge of the Shrill carder bee Bombus sylvarum in the UK. It is a working document, with a view to this information being reviewed and added when needed (current version updated Oct 2019). Special thanks to the group of experts who have reviewed and commented on earlier versions of this report. Much of the current knowledge on Bombus sylvarum builds on extensive work carried out by the Bumblebee Working Group and Hymettus in the 1990s and early 2000s. Since then, there have been a few key studies such as genetic research by Ellis et al (2006), Stuart Connop’s PhD thesis (2007), and a series of CCW surveys and reports carried out across the Welsh populations between 2000 and 2013. Distribution and abundance Records indicate that the Shrill carder bee Bombus sylvarum was historically widespread across southern England and Welsh lowland and coastal regions, with more localised records in central and northern England. The second half of the 20th Century saw a major range retraction for the species, with a mixed picture post-2000. Metapopulations of B. sylvarum are now limited to five key areas across the UK: In England these are the Thames Estuary and Somerset; in South Wales these are the Gwent Levels, Kenfig–Port Talbot, and south Pembrokeshire. The Thames Estuary and Gwent Levels populations appear to be the largest and most abundant, whereas the Somerset population exists at a very low population density, the Kenfig population is small and restricted. -
Journal of Melittology Bee Biology, Ecology, Evolution, & Systematics the Latest Buzz in Bee Biology No
Journal of Melittology Bee Biology, Ecology, Evolution, & Systematics The latest buzz in bee biology No. 13, pp. 1–11 26 July 2013 A new species, Lasioglossum (Eickwortia) hienae, from Mexico (Apoidea: Halictidae) Jason Gibbs1 & Sheila Dumesh2 Abstract. A new species from Colima, Mexico, Lasioglossum (Eickwortia) hienae Gibbs & Du- mesh, new species, is described and illustrated. Lasioglossum hienae is distinguished from re- lated species based on a combination of morphological, geographical, and molecular evidence. A species distribution model is used to predict the potential distribution of the known species of L. (Eickwortia). An identification key is provided. INTRODUCTION The bee genus Lasioglossum Curtis (1833) is exceptionally diverse in terms of species richness, habitat use, and social behavior (Michener, 1974, 1979, 2000, 2007; Yanega, 1997; Schwarz et al., 2007). Eickwortia McGinley, 1999, now recognized as a subgenus of Lasioglossum (Michener 2000, 2007), was proposed for two species of high- elevation bees in Mexico and Central America, Lasioglossum nyctere (Vachal, 1904) and L. alexanderi (McGinley, 1999). Lasioglossum (Eickwortia) belongs to the informal group known as the Hemihalictus series, which is recognizable by its weak distal wing vena- tion (Michener, 2007). Ascher & Pickering (2013) have included these two species in L. (Evylaeus) Robertson, a subgenus we treat in a much narrower sense (Gibbs et al., 2013). The taxonomic limits of Lasioglossum subgenera require revision (Gibbs et al., 2012b, 2013), but recognition of the subgenus L. (Eickwortia) seems reasonable based on its apomorphic traits, including infuscate wings, strongly bidentate mandibles of the females, and slender metasoma of the males. We are reluctant to describe new species based on few specimens, but in the case of rare bees like L. -

Focusing on data-rich studies, we also synthesize recent research on potential causes of population declines. There is evidence that habitat loss, changing climate, pathogen transmission, invasion of nonnative species, and pesticides, oper- ating individually and in combination, negatively impact bumble bee health, and that effects may depend on species and locality. -

A neglected aspect of small-scale variation of plant-pollinator interactions is the role of vertical 14 position of flowers. We conducted a series of experiments to study vertical stratification of plant-pollinator 15 interactions in a dry grassland. We observed flower visitors on cut inflorescences of Centaurea scabiosa 16 and Inula salicina placed at different heights above ground in two types of surrounding vegetation: short 17 and tall. Even at such a small-scale, we detected significant shift in total visitation rate of inflorescences 18 in response to their vertical position. In short vegetation, inflorescences close to the ground were visited 19 more frequently, while in tall vegetation, inflorescences placed higher received more visits. -
Notes on Alien and Native Bees (Hymenoptera: Apoidea) from the Hawaiian Islands1

Both of the new Lasioglossum species are relatively recent arrivals, but their precise date of introduction is not known because the alien Lasioglossum are often ignored by collectors and are poorly represented in collections. it had been assumed that all were L. impavidum (Sandhouse, 1924), which has been present in the islands since at least 1957 (Beardsley 1958, Beardsley 1959). A recent survey of o‘ahu lowland disturbed sites by Sd found three distinct species – L. impavidum , L. imbrex Gibbs, 2010, and L. microlepoides (ellis, 1914) – prompting a review of earlier specimens.

Portland, OR: The Xerces Society for Invertebrate Conservation. ________________________________________________________________________ Halictus harmonius Sandhouse, 1941 (Halictidae: Halictinae: Halictini) ________________________________________________________________________ Prepared by Dr. Laurence Packer, York University. ________________________________________________________________________ SUMMARY Halictus harmonius is a rare localized species that has only ever been recorded from the foothills of the San Bernardino and, but with less certainty, from the San Jacinto mountains in Southern California. This whole area is subject to considerable anthropogenic disturbance through construction, pollution and agriculture. The species is active for long periods in spring and summer and appears to be primitively eusocial with macrocephalic queens and smaller workers. It appears not to be restricted in pollen and nectar source plants. A survey of suitable habitat in the small area from which the species is known is badly required.

This is the only subgenus of Halictine bee in North America that has the combination of greenish metallic coloration and apical bands of pale hairs on the metasomal terga. Halictine bees can be readily identified on the basis of the strongly curved basal vein and, except in certain cleptoparasitic forms, by the pseudopygidial area on female T5. -

Decline in the populations of bumble bees and other pollinators stress the need for more knowledge about their conservation status. Only one of the 25 bumble bee species present in Hungary is included in the Hungarian Red List. We estimated the endangerment of the Hungarian bumble bee (Bombus Latr.) species using the available occurrence data from the last 50 years of the 20th century. Four of the 25 species were data deficient or extinct from Hungary. About 60% of species were considered rare or moderately rare. Changes in distribution and occurrence frequency indicated that 10 of the 21 native species showed a declining trend, while only three species in- creased in frequency of occurrence. According to the IUCN Red List categories, seven species (33% of the native fauna) should be labelled as critically endangered (CR) and 3 (14%) as endangered (EN). Our results stress an urgent need of protection plans for bumble bees in Hungary, and further underlines the validity of concern over bumble bees all over Europe. -

Lasioglossum Sexstrigatum (Hymenoptera: Apidae, Halictinae) New to Britain
90 BR. J. ENT. NAT. HIST., 24: 2011 LASIOGLOSSUM SEXSTRIGATUM (HYMENOPTERA: APIDAE, HALICTINAE) NEW TO BRITAIN ROGER D. HAWKINS 30D, Meadowcroft Close, Horley, Surrey RH6 9EL ABSTRACT A female Lasioglossum sexstrigatum (Schenck), a species not previously known in Britain, was found in a sandpit near Merstham in Surrey in June 2008. Despite several searches, no further specimens of this bee have been recorded from this site. Recent evidence shows this species is widely distributed in central mainland Europe. INTRODUCTION AND DISCOVERY Small black bees, particularly those in the genus Lasioglossum, form a difficult area of study for the student of aculeate Hymenoptera, but can be identified with some confidence by careful use of a key and with reference to a reliably named collection. One such insect, a female bee taken at a flooded sandpit near Merstham in east Surrey, caused particular difficulty. This bee was small (6mm long) and black, the angles of the propodeum were rounded, and the marginal area of tergite 1 was shining, almost smooth, and without punctures. The specimen had one very distinctive feature: there was a narrow band of dense white hairs towards each side of the apical margin of each of tergites 2 to 4 (Plate 7, Fig. 2). The bee was given several different provisional names before being identified conclusively as Lasioglossum sexstrigatum (Schenck), a European species not previously recorded in Britain. The site is owned by WBB Minerals, part of the Sibelco Group, and since 2002 has been managed as a nature reserve by the Surrey Wildlife Trust under the name of Spynes Mere. -
