These data were collected to estimate detection probability of Bombus affinis at known occupied sites in Wisconsin, Minnesota, Illinois, and Iowa in 2021. Data were also used to determine the effect of weather, observer experience, and habitat quality on Bombus affinis detection probability.

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.

USGS personnel surveyed bumble bees and flowering plants on private and public lands in Central Montana. These data provide a summary of what was found, including the number of bumble bees caught during standardized netting surveys and a comprehensive list of all plants in flower within survey plots during each site visit.

Bumblebee community surveys used occupancy survey designs primarily across lands managed by the Bureau of Land Management (BLM) and Glacier National Park (GNP). They also include a few surveys in Nevada. These records represent timed surveys that were both successful and unsuccessful in detecting western bumblebees.

High-throughput methods for identification of pollinator taxa are desirable to improve our understanding of pollinator distributions, population trends, and ecology. Genetic sequencing of taxonomically informative 'barcode' loci is one high-throughput strategy, which can be applied to individual specimens using Sanger technology and to complex mixtures using metabarcoding technology. This study generated Sanger sequencing data from morphologically identified specimens and metabarcoding data derived from pooled tissues. This data release consists of several files: 1. sample.metadata.txt, which contains sampling metadata and identifiers linking to sequence data that has been deposited in the Sequence Read Archive...

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.
