Abstract: The area sourrounding the Mediterranean basin is recognised as a major biodiversity hotspot for bees, and Italy is amongst the European countries with the highest bee species richness. Detailed knowledge of bee distribution is crucial for understanding bee biology and designing tailored conservation strategies, but is still insufficient in southern European countries, especially in Italy.We report recent finds of 48 bee species that yield significant novelties for the Italian bee fauna. Eight species, namely Andrena confinis Stöckhert, Anthidiellum breviusculum Pérez, Coelioxys alatus Foerster, Lasioglossum algericolellum Strand, Megachile lapponica Thomson, Megachile opacifrons Pérez, Megachile semicircularis auct. nec Zanden and Trachusa integra Eversmann are reported as new for Italy. In addition, Andrena binominata Smith, Andrena compta Lepeletier, Colletes acutus Pérez, Lasioglossum strictifrons Vachal, Rhodanthidium siculum Spinola and Rhodanthidium sticticum Fabricius are newly recorded from mainland Italy, Osmia heteracantha Pérez from Sardegna and Nomada flavopicta Kirby from Sicilia. We also report significant range extensions for other bee species and recent records of species that had long gone unrecorded in Italy. The combination of morphology and DNA barcoding provided reliable identifications even for the most challenging specimens. As several of our records come from areas neglected by bee experts in the past, this study stands out as a key indicator of a bee faunistic richness still awaiting discovery and hopefully it will stimulate the interest of taxonomists and stakeholders in pursuing bee research in Italy in the near future.

Apoidea of the collections of Lyon, Aix-en-Provence, Marseille and Toulon Museums of Natural History (France) https://bdj.pensoft.net/article/99650/ Biodiversity Data Journal 11: e99650

DOI: 10.3897/BDJ.11.e99650

Authors: Jean-Yves Meunier, Benoît Geslin, Mehdi Issertes, Gilles Mahé, Frédéric Vyghen, Harold Labrique, Yves Dutour, Vincent Poncet, Jérémy Migliore, Gabriel Nève

Abstract: Many insect species have shown dramatic declines over the last decades, as a result of man-related environmental changes. Many species which were formerly widespread are now rare. To document this trend with evidence, old records of collected specimens are vital.We provide here the data on 9752 bee (Hymenoptera: Apoidea) specimens hosted in several museums of south-east France: Musée des Confluences in Lyon, Muséum d’Histoire Naturelle de Marseille, Muséum d’Aix-en-Provence and the Muséum Départemental du Var in Toulon. Most of the specimens (9256) come from France and include data on 552 named species. For most of these specimens, the geographical location, including geographical coordinates, is based on the locality (town or village) where they were collected. The specimens were captured from the beginning of the nineteenth century to 2018. The identifications of 1377 specimens, mainly belonging to the genus Bombus, are considered reliable, as these were performed or been checked since 2009. All the other reported identifications are the original ones given by the original collectors.

The FloRes Database: A floral resources trait database for pollinator habitat-assessment generated by a multistep workflow https://bdj.pensoft.net/article/83523/ Biodiversity Data Journal 10: e83523

DOI: 10.3897/BDJ.10.e83523

Authors: Franziska Baden-Böhm, Mario App, Jan Thiele

Abstract: The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. The feeding of those insects depends on the spatial and temporal distribution of nectar and pollen as food resource. Hence, to protect insect biodiversity, a spatio-temporal assessment of food quantity of their habitats is necessary. Therefore, sufficient data on traits of floral resources are required.As floral resources’ traits of plants are important to quantify food availability, we present two databases, the FloRes Database (Floral Resources Database) and the raw database, from where FloRes was derived. Both databases contain the plant traits: (1) flowering period, (2) floral-unit density per day, (3) nectar volume per floral unit per day, (4) sugar content per floral unit, (5) sugar concentration in nectar, (6) pollen mass or volume per floral unit and per day, (7) protein content of pollen and (8) corolla depth. All traits were sampled from literature and online databases. The raw database consists of 702 specified plant species, 138 unspecified species 37 species (spec., sp), 22 species pluralis (spp) and, for 79, only the genus was identified) and two species complexes (agg.). Those 842 taxa belong to 488 genera and 102 families. Finally, only 27 taxa have a complete set of traits, too few for a sufficient assessment of spatio-temporal availability of floral food-resources.As information on floral resources is scattered throughout many publications with different units, we also present our multistep workflow implemented in five consecutive R-scripts. The multistep workflow standardises the trait units of the raw database to comparable entities with identical units and aggregates them on a reasonable taxonomic level into the second application database, the FloRes Database. Finally, the FloRes Database contains aggregated information of traits for 42 taxa and, when corolla depth is excluded, for 72 taxa.This is the first attempt to gather these eight traits from different literature sources into one database with a multistep workflow. The publication of the multistep workflow enables the users to extend the FloRes Database on their own demands with other literature data or newly-gathered data to improve quantification of food resources. Especially, the combination of pollen, nectar and the open flowers per square metre is, as far as we know, a novelty.The FloRes Database can be used to evaluate the quantity of food-resource habitats available for pollinators, for example, to compare seed mixtures of agri-environmental measures, such as flower strips, considering flower phenology on a daily basis.

Expanded range of eight orchid bee species (Hymenoptera, Apidae, Euglossini) in Costa Rica https://bdj.pensoft.net/article/81220/ Biodiversity Data Journal 10: e81220

DOI: 10.3897/BDJ.10.e81220

Authors: Elise McDonald, Jacob Podesta, Christine Fortuin, Kamal Gandhi

Abstract: The Monteverde region of Costa Rica is a hotspot of endemism and biodiversity. The region is, however, disturbed by human activities such as agriculture and urbanisation. This study provides a list of orchid bees (Hymenoptera: Euglossini) compiled from field surveys conducted during January-October 2019 in the premontane wet forest of San Luis, Monteverde, Costa Rica. We collected 36 species of Euglossine bees across four genera. We provide new geographic distribution and elevation data for eight species in two genera. Due to their critical role in the pollination of orchids and other plants, the distribution and abundance of Euglossine bees has relevance to plant biodiversity and conservation efforts. This is especially important in a region with a high diversity of difficult-to-study epiphytic orchids, such as in the Monteverde region.A total of 2,742 Euglossine male individuals across four genera (Eufriesea, Eulaema, Euglossa and Exaerete) were collected in this study. Updated geographic distributions and elevation ranges were established for eight species of Euglossini in two genera: Eufriesea mussitans (Fabricius, 1787), Eufriesea rufocauda (Kimsey, 1977), Euglossa dodsoni (Moure, 1965), Euglossa dressleri (Moure, 1968), Euglossa hansoni (Moure, 1965), Euglossa ignita (Smith, 1874), Euglossa tridentata (Moure, 1970) and Euglossa turbinifex (Dressler, 1978). These are the first recorded occurrences of these species in the Monteverde region of Costa Rica, according to the Global Biodiversity Information Facility (GBIF) database (https://doi.org/10.15468/9f9kgp). This study also established expanded elevation ranges for Euglossa allosticta, Euglossa bursigera, Euglossa mixta, Euglossa heterosticta and Euglossa maculabris, though these five species have been previously recorded in the Monteverde region and, thus, are not described in detail here. Additionally, our capture of 123 Eufriesea concava individuals is significant, as it indicates its abundance in this region. Prior to this study, there was a single record of E. concava in the Monteverde region, documented in 1993.

Distribution of wild bee (Hymenoptera: Anthophila) and hoverfly (Diptera: Syrphidae) communities within farms undergoing ecological transition https://bdj.pensoft.net/article/60665/ Biodiversity Data Journal 9: e60665

DOI: 10.3897/BDJ.9.e60665

Authors: Grégoire Noel, Julie Bonnet, Sylvain Everaerts, Anouk Danel, Alix Calderan, Alexis de Liedekerke, Clotilde de Montpellier d'Annevoie, Frédéric Francis, Laurent Serteyn

Abstract: In Havelange (Belgium), two farms are experimenting an ecological transition. We aimed to evaluate the impact of their agricultural activities on insect pollinator communities. This article depicts the situation at the very early stage of the farm transition. This study supports the environmental benefits that the agricultural diversification with the maintenance of farm-level natural habitats can provide to the conservation of two important pollinator communities: wild bees and hoverflies.Over two years (2018-2019), by using nets and colored pan-traps, we collected 6301 of bee and hoverfly specimens among contrasted habitats within two farmsteads in ecological transition at Havelange (Belgium). In combination with the historical data of the region, we reported 101 bee species and morphospecies from 15 genera within 6 families and 31 hoverfly species and morphospecies from 18 genera. This list reinforces the national pollinator database including new distribution data in the region for extinction threatened species such as Andrena schencki Morawitz, 1866, Bombus campestris (Panzer, 1801), Eucera longicornis (L.), Halictus maculatus Smith, 1848 and Melitta tricincta Kirby, 1802 or for data deficiency species such as A. semilaevis Pérez, 1903, A. fulvata (Müller, 1766), A. trimmerana (Kirby, 1802) and Hylaeus brevicornis Nylander, 1852.

Male sleeping aggregation of multiple Eucerini bee genera (Hymenoptera: Apidae) in Chapada Diamantina, Bahia, Brazil https://bdj.pensoft.net/article/1556/ Biodiversity Data Journal 2: e1556

DOI: 10.3897/BDJ.2.e1556

Authors: Thiago Mahlmann, Juliana Hipólito, Favízia de Oliveira

Abstract: Males of some groups of bees have to find a place outside the nests to sleep, sometimes forming “male sleeping aggregations”. Here we report the first record of “dense” male sleeping aggregation of two different genera of Eucerini bees observed in Bahia, Brazil. We discuss the possible aim of this kind of aggregation as well the plant utilized on aggregate.

Why is the lawn buzzing? https://bdj.pensoft.net/article/1101/ Biodiversity Data Journal 2: e1101

DOI: 10.3897/BDJ.2.e1101

Authors: Timothy Jones

Abstract: Graminoids, including grasses, are frequently described in the botanical literature as being wind-pollinated. This paper offers visual evidence for insect pollination of a grass. Three of the bees involved were found to have 100% grass pollen in their pollen sacs. In reviewing the literature for this paper, it was evident that those working with bees are well aware that these insects often pollinate graminoids. It is not clear why this information has not been incorporated into the botanical literature.
