Species occurrence records for native and non-native bees, wasps and other insects collected using mainly pan, malaise, and vane trapping; and insect netting methods in Canada, Mexico, the non-contiguous United States, U.S. Territories (specifically U.S. Virgin Islands), U.S. Minor Outlying Islands and other global locations with the bulk of the specimens coming from the Eastern United States often from Federal lands such as USFWS, NPS, DOD, USFS. Some records also contain notes regarding plants or substrates from which insects were collected or that were present and/or in flower at the time the insects were collected. Unless otherwise noted, taxonomic determinations (identifications) were completed by Sam Droege (USGS Eastern Ecological Science Center- EESC, Native Bee Laboratory) and Clare Maffei (USFWS, Inventory and Monitoring Branch). The EESC Native Bee Lab currently keeps only a small synoptic collection, rare and voucher specimens are deposited in the Smithsonian National Collection (NMNH) and widely distributed to other institutions for DNA, revisions, and augmentation of existing collections. Surplus specimens are also made available to students to learn their identifications. Corrections to any of our determinations are always welcomed. Common species that are not in demand for surplus are usually destroyed and the pins recycled. Recent revisions to Lasioglossum, Ceratina, and to a much lesser extent Triepeolus and Epeolus and other small groups have rendered determinations prior to those revisions out of date for species involved in name changes and users should account for that during analyses. Current data (included information on specimen codes without identifications) are always available without charge directly from Sam Droege.

The Buenos Aires National Wildlife Refuge (BANWR), along the Mexican border in southern Arizona, is host to a rich community of bird and mammal species, many of which rely on seed-bearing plants for sustenance. Native bees (Anthophila) provide pollination services vital to the reproduction of such plants, and some of Earth’s highest bee diversity has been documented within the broader Sonoran Desert region. Native bees are historically under-monitored, especially in remote, unpopulated, and inaccessible regions. As the climate warms, global declines in native bee populations have underscored the importance of bee monitoring projects. Without baseline occurrence data, tracking the changing status of bee populations is nearly impossible. Despite the diversity of the region and urgent need for monitoring bee populations, the bee fauna of BANWR has not been methodically sampled. We conducted a survey of the BANWR bee fauna at least once a month from May 2019 to March 2020, using blue vane traps at each of eight sites within the refuge. Our sites varied in elevation, precipitation, associated plants, and fire treatment. A total of 39 distinct bee genera were documented across all sites. These data can be used to inform a monitoring program for pollinator health at BANWR.

Data included in this data set are for blue vane trap captured native bees from Logan County, Colorado starting in 2012 and ending in 2014. Data were collected the number of bees captured per date, per field, and identified to genus. Net level data contains 16,229 records.

These raw survey data and associated explanatory covariates were used to model western bumble bee occupancy across the western conterminous United States from 1998 to 2020. These data underlie the analyses found in the publication of “Recent and future declines of a historically widespread pollinator linked to climate, land cover, and pesticides” by Janousek et al. 2023 in the Proceedings of the National Academy of Sciences vol. 120, issue 5. The covariate data are provided in a scaled format for use in the occupancy model, and the scaling parameters used to transform the data to the original (real) scale are provided in the scaling information file.

This data release includes sampling location identification and timing data as well as plant and insect pollinator taxonomic information in Conservation Reserve Program fields. Sampling took place during July and August of 2019. Fields were located on private land managed for the U.S.Department of Agriculture Conservation Reserve Program in eastern central Iowa, U.S.A.

Bee-Gap describes the ecology, life-history, and distribution of 3,925 bee species in the United States that have geographical data and verified taxonomy. The database was constructed by compiling information from a broad range of internet sources and peer-reviewed journal articles. The 10 traits included in the database are: native status (native versus exotic/introduced), state and territory presence/absence, adult habitat, nesting strategy, voltinism, sociality, host bee species (for parasitic bees only), foraging strategy (generalist vs specialist), known host plants, and tongue length.
