Biodiversity Data Journal 11: e99650. https://doi.org/10.3897/BDJ.11.e99650 Abstract Background 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. © Meunier J et al.

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. Keywords Hymenoptera, bees, museum, France, record, Apoidea, Bombus, Apidae, Halictidae, Andrenidae, Megachilidae, Colletidae, Melittidae Introduction There has been a dramatic decline in insect populations over the last 70 years, both in terms of abundance (Hallmann et al. 2017, Seibold et al. 2019) and diversity (Raven and Wagner 2021). To document the past occurrences of species in areas where they have now decreased or vanished, entomologists mostly rely on material preserved in collections (e.g. Decker et al. (2020), Mathiasson and Rehan (2020)). Museum materials are what remains of past ecosystems; for some species, they represent the last testimony of their presence in a region or country and it appears crucial to extract as much information as possible from these specimens (Raven and Miller 2020), such as photographs of key specimens. In many natural history museums around the world, there are thousands of specimens stored in collections for which we barely have any information. This is particularly the case for insects, which are difficult to preserve because of pests and difficult to identify due to the taxonomic impediment (Engel et al. 2021). Yet, the importance of insects in the functioning of ecosystems should urge precise monitoring of museum collections contents. In the present time of rapid anthropogenic ecological changes at all scales, we must find ways to preserve these specimens as well as we can for as long as we can. They are vulnerable to degradation and loss from pests (Verlinden 2020), humidity (Clary 1991), fire (Escobar 2018) and the toll of time. While renewing efforts to protect them, we need to make them more accessible through digitisation, including imaging (Paterson et al. 2016) and, for a representative series of specimens, the sequencing of COI and other genes. Apoidea of the collections of Lyon, Aix-en-Provence, Marseille and Toulon ... 3 Amongst the various roles of insects in ecosystems, the pollination process is a key component, both in natural and man-made ecosystems (Hristov et al. 2020). Amongst pollinators, Hymenoptera is often considered as the most important insect order to pollinate flowers, followed by Diptera and Lepidoptera (Walton et al. 2020). Amongst Hymenoptera, Anthophila (bees sensu lato) is the main group of pollinators. The French bee fauna currently includes 978 species (Ropars, pers. comm.). Work is currently in progress both in revising the taxonomy of species groups which are not covered by recent reliable keys (e.g. Le Divelec (2021) on Epeolus genus) or in regional lists (e.g. Terret et al. (2020) for Franche-Comte). Despite these recent revisions, the available information about the diversity of bees within the French territory, both current and past, is still very incomplete. The design and implementation of effective conservation measures rely on the knowledge of both current and historic distribution of species (Schatz et al. 2021), which in turn, relies on the knowledge on the bee species distribution within the French territory. The aim of the present paper is to document the collections of Apoidea hosted by the Musée des Confluences in Lyon (MHNL), the Muséum dHistoire Naturelle de Marseille (MHNM), the Muséum d’Aix-en-Provence (MHNAix) and the Museum Departemental du Var (MDV) in Toulon (Table 1). The Musée des Confluences holds the second most important Natural history collection in France, after the Paris Museum National d’Histoire Naturelle. It was founded in 1772 (Clary 1995). The Marseille Museum, founded in 1819, currently holds a collection of ca. 84,000 zoological specimens (Lima and Medard 2021). The Aix Museum was founded in 1838 (Sepulveda and Dutour 2006) and hosts an important collection of insects collected in the vicinity of Aix-en-Provence in the nineteenth century (Dusoulier 2006). Ultimately, the knowledge of past occurrences of bees will be of outmost importance for documenting the evolution of bee richness and their distribution in France and to set the basis for a future French Red List of bees which still does not exist to this day. General description Purpose: The aim of this publication is to make public the records of Apoidea stored in the four natural history Museums of south-east France. Researchers will, therefore, know where the specimens are stored, how numerous they are and when and where they were collected. Information on who identified the specimens and when is also given, as this is important given the on-going changes in the taxonomic treatment of many species ( Rasmont et al. 2017, Gargominy et al. 2021). The past status of species now rare may then be assessed at a regional level and the original specimens may then be localised, studied and re-identified if needed.

Most original labels include location (usually the municipality), date (sometimes only partly, such as the month), collector and an assigned species name. As the taxonomy of the Apoidea has dramatically changed over the last 150 years, we believe that an important part of the old material should be re-identified according to current knowledge. This could be done only for a part of the specimens: Bumblebees (Bombus) in the Musée des Confluences were recently revised by MI, GM and FV and all specimens at the MDV were _ identified since 2009; their identification VerificationStatus column was coded “1”. The data on all the other specimens have retained their original species identification and the identificationVerificationStatus column was coded “0”. The collectors of Apoidea specimens in the four Museums were: René Grilat (?-1915) [2645 specimens], Georges Audras (1881 -1970) [2028 specimens], Maurice Dauzet (1927-2021) [1752 specimens], Claudius Cote (1881-1956) [821 specimens], Jean Timon- David (1902-1968) [606 specimens], Pierre Real (1922-2009) [892 specimens], Jean- Hubert Chabrier (1791-1884) [240 specimens], Claude Dufay (1926-2001) [133 specimens], Philippe Grivot [131 specimens], Nicolas Bermante [128 specimens], Jacques Hamon (1926-2022) [56 specimens], Guy Chavanon (born 1951) [78 specimens], Robert Apoidea of the collections of Lyon, Aix-en-Provence, Marseille and Toulon ... 5 Gonon (1908-1994) [53 specimens], Roland Allemand (1950-2013) [29 specimens] and several others. Sampling description: On top of the data given on the original labels, we have added the Department (French administrative division) and the coordinates of the centre of the locality where each specimen was collected (columns decimalLatitude and decimalLongitude). This gives an approximation of ca. 5 km, depending on each locality size. Quality control: The specialists whose recent identifications we relied on are Holger Dathe (genus Hylaeus), Robert Fonfria (mainly Families Megachilidae and Andrenidae), David Genoud (genus Andrena), Michael Kuhlmann (genus Colletes), Gérard Le Goff (genus Anthophora), Hugues Mouret (genera Anthophora and Andrena), Alain Pauly (family Halictidae), Stephan Risch (genus Eucera) and Erwin Scheuchl (genus Andrena) for the 89 specimens in the MDV collections and MI, GM and FV for 1288 Bombus specimens in MHNL. Step description: The collections of Apoidea in the Natural History Museums of Aix-en- Provence, Lyon, Marseille and Toulon were surveyed systematically. A total of 9752 specimens were recorded. A total of 1377 French specimens were either checked in MHNL or identified recently by various specialists, as in the case of the specimens from Porquerolles (Hyeres, Var) in MDV. For all other specimens, the nomenclature was checked against the list of European bees used for the IUCN Red List (Nieto et al. 2014). If the original species name did not appear in this reference list, a search was done on hitip://westpalbees.myspecies.info and https:// www.bwars.com/search/node/Caelioxis websites to find the name currently used for names recognised as synonyms. The current name was, thus, mentioned in the scientificName column, whereas the name given by the original identifier was put into the previousidentifications column. If the original name could not be assigned unambiguously to a current name or if no identification had been given, no current species name was given in the data set. As far as possible, the locality of origin of the specimen was identified and its latitude and longitude given by the website https:/Awww.geoportail.gouv.fr/ was input. In a few cases, such as passes or forests between neighbouring localities, the precise coordinates of the location were input. In the CSV dataset format, fields are separated by tabs, all encoding is UTF-8, which allowed for all diacritic signs to be retained. Apostrophes (') were used wherever appropriate in locality names. Uncertain readings from the labels are indicated by a question mark in the verbatimEventDate or verbatimLocality fields. If the locality name was uncertain, no coordinates were given. Geographic coverage Description: The Apoidea specimens mainly come from south-east France (Fig. 1), but also include specimens from 24 other countries: Algeria [10], Austria [6], Brazil [2], Chad 6 Meunier J et al [1], Czech Republic [46], Germany [7], Greece [10], Guatemala [1], Hungary [3], Indonesia [1], Italy [4], lvory Coast [2], Luxembourg [2], Morocco [8], The Netherlands [31], Romania [1], Slovakia [2], Spain [8], Switzerland [6], Tunisia [15], Turkey [9], United Kingdom [22], USA [1] and former Yugoslavia [2]. The country of origin of 296 specimens could not be traced. The 9256 specimens from France come from 61 Departments (Table 2), mainly Rhéne (4253 specimens), Loire (1141 specimens), Bouches-du-Rhéne (874 specimens) and Ain (554 specimens). The localities of 139 specimens could not be traced to a Department. Table 2. Numbers of French Apoidea specimens, sorted by French Departments.

A total of 9256 specimens are from mainland France or Corsica (Fig. 1) and 295 specimens have no locality information. All the following analyses are based on mainland France and Corsica data only. Unfortunately, 5002 of the 9255 French specimens do not bear a date of collection. For some of these, the time frame was guessed using the biographic data of the collectors. If we hypothesise that the specimens from the Chabrier Collection were collected during the first half of the 19"" century and the ones from Céte Collection during the first half of the 20 ‘h century, most of the specimens were collected since 1900, equally divided (about 1500 specimens) in each of the time spans 1900-1949, 1950-1999 and 2000-2018 (Fig. 2). The 4253 specimens with accurate collection data (day, month, year) date from 1881 to 2018. The temporal distribution of the data according to the IUCN criteria of the European fauna (Nieto et al. 2014) shows that most specimens belonging to endangered species were collected either in the years 1901-1950, or in the years 2000-2018 (Fig. 3, Fig. 4). Only one specimen, captured between 1950 and 2000, belonged to an endangered species (Trachusa interrupta), whereas a total of eight specimens of endangered species have been collected since 2000 (Table 5). On the other hand, four endangered species have no data since 1950: Lasioglossum quadrisignatum, Lasioglossum subfasciatum, Melitta melanura and Osmia maritima, leaving the question open as to whether they still occur in France. Altogether, the dataset holds data on ten species listed as endangered (Table 5) and eight species classified as vulnerable in Europe (Table 6). Table 5.
