Abstract

Background

Wild bees that were collected in conjunction with a larger study are presented as a checklist of species for the Northern Rockies Ecoregion of Montana, USA. Over the course of four field seasons (2013-2016), 281 species and morphospecies in 32 genera and five families were collected using insect nets, and identified. This paper addresses the distinct lack of studies monitoring bee species in Montana and contributes to a basic understanding of fauna in the northern Rocky Mountains.

New information

With this study, the number of known bee species in Montana increases by at least six species, from 366 (Kuhlman and Burrows 2017) to 372. Though literature was not reviewed for all the species on this checklist, published records in Montana revealed no listings for Andrena saccata Viereck; Anthidiellum notatum robertsoni (Cockerell); Ashmeadiella meliloti (Cockerell); Ashmeadiella pronitens (Cockerell); Colletes lutzi lutzi Timberlake; and Dioxys productus (Cresson).

Introduction

Faunistic studies characterizing native pollinators are becoming more important for understanding patterns in local and regional biodiversity as species are threatened by habitat loss, climate change and other factors (Green et al. 2005, Lengyel et al. 2008, Losos et al. 2013). Studies documenting wild bee species are particularly critical because bees are the world's primary animal pollinators in most ecosystems (Neff and Simpson 1993, Winfree 2010) and are currently undergoing declines across different spatial scales (Koh et al. 2015), including globally (Council, Natural Resource 2007). Much taxonomic work has focused on regional bee fauna in the eastern United States and several states in the western U.S., however there remains a dearth of studies documenting wild bees in Montana (but see Dolan et al. 2017 and Kuhlman and Burrows 2017).

Here we present a list of bee species from three localities in the northern Rocky Mountains collected over the course of four years as part of a larger project investigating the effects of wildfire on plant-pollinator diversity (Burkle et al. 2015). This paper contributes to the regional list of wild bees in Montana and addresses the need for pollinator monitoring in the western U.S.

Materials and methods

Study Region

The Northern Rockies Ecoregion (NRE) encompasses 162,746 km² of Idaho, western Montana and northeastern Washington, and is characterized by high, rugged mountain ranges consisting of montane, alpine and subalpine ecosystems (Taylor 2012). Dominant vegetation includes lodgepole pine (Pinus contorta), ponderosa pine (Pinus ponderosa), western larch (Larix occidentalis), and mixed conifer forests. Climate in the NRE is dry, with most precipitation occurring as snow, and with very cold winters and short summers (Table 1). We collected bee specimens from the following three localities within the NRE: near Glacier National Park in Flathead County, Absaroka-Beartooth Wilderness in Park County, and Helena National Forest in Lewis and Clark County (see Fig. 1).

Collection Methods

At each locality, we established nine 25m diameter circular plots within each of four 15 hectare study blocks. Study blocks were located within previously determined wildfire perimeters. Within a block, plots were randomly stratified to meet research goals related to wildfire severity and to avoid spatial clumping of plots using a generalized random tessellation stratified (GRTS) survey design function in the R spsurvey package (Kincaid and Olsen 2011). Details of site selection and characteristics can be found in Burkle et al. 2015.

Bees were collected over four field seasons (2013-2016) beginning when plants started to bloom after snowmelt (late-May or June) and ending once most flower species had gone to seed (late-August). Collection dates for each species can be found in Supplementary Data Table 1 (Suppl. material 1). Each locality was sampled as often as possible per season, with sampling bouts being chiefly determined by weather. On every visit to a locality, we sampled each plot for 20 minutes. All insects that contacted the reproductive parts of flowers were collected with insect nets, pinned, and labeled with pertinent data, including plant species association. We visited the Lewis and Clark County locality five times in 2013, thirteen times in 2014, nine times in 2015 and seven times in 2016. At the Park County location, we visited two, eleven, nine, and six times in 2013, 2014, 2015 and 2016, respectively; and we visited the Flathead County location three times in 2013, and seven times in both 2014 and 2015.

Species Identification

Bee species were identified by Elizabeth Reese, Terry Griswold, Casey Delphia, Skyler Burrows, Harold Ikerd, Michael Orr, Jason Gibbs and Karen Wright. To make determinations to the lowest possible taxonomic level we used published keys or unpublished works where these were available (Table 2). When keys were not sufficient, or did not exist for this area, we designated morphospecies based on morphological characteristics. Morphospecies were labeled "F" for female or "M" for male and given unique numbers. In cases where two particular species were impossible to differentiate based on morphology, both species names were notated (i.e., females of Agapostemon texanus/angelicus). Specimens are deposited in the Montana State University Pollinator Health Center Collection located in the Burkle Community Ecology Lab at Montana State University in Bozeman, MT and the U.S. National Pollinating Insect Collection in Logan, UT.

Analysis

We collected 8011 bee specimens representing 281 species and morphospecies in 32 genera and five families between 2013 and 2016. Following are the total number of specimens by family (to avoid inflating species richness, we did not include male morphospecies in species counts because female morphospecies may have been the same species): Colletidae: 357 specimens, 2 genera, 17 species; Andrenidae: 395 specimens, 3 genera, 44 species and morphospecies; Halictidae: 1251 specimens, 4 genera, 55 species and morphospecies; Megachilidae: 2920 specimens, 12 genera, 113 species and morphospecies; Apidae: 3088 specimens, 11 genera, 52 species and morphospecies.

Though resources did not allow for a comprehensive literature search to assess new state records for all the species on this checklist, an exploratory search for 25 of the species (in no particular order) revealed no previously published records in Montana for Andrena saccata Viereck; Anthidiellum notatum robertsoni (Cockerell); Ashmeadiella meliloti (Cockerell); Ashmeadiella pronitens (Cockerell); Colletes lutzi lutzi Timberlake; and Dioxys productus (Cresson). In addition, Dolan et al. (2017) reported a specimen of Bombus borealis Kirby from this study to be a first Montana state record. In effect, this brings the number of known bee species in Montana up from 366 (Kuhlman and Burrows 2017) to at least 372, and indicates a clear need for more extensive bee surveys in the state.

Discussion

Because Montana spans a large area of diverse topography, landscape and climate (Dolan et al. 2017), species groups are likely to vary among different locations. For instance, compared with a checklist of bees from a similar montane habitat in Montana (Kuhlman and Burrows 2017), there was some overlap among species, with 121 species (not including morphospecies) in common with our list, but also some variability, with 126 species unique to our study. When compared to an unpublished study on bees associated with native flower strips around agricultural fields in the Gallatin Valley, Montana (C.M. Delphia pers. com.), the species suites included 117 species in common and 130 unique to our study. We expect that future biosurvey efforts will reveal hundreds of species not yet listed in Montana.

There is growing evidence of declines in wild bee species diversity (Winfree et al. 2009, Winfree 2010, Potts et al. 2010, Burkle et al. 2013, Goulson et al. 2015, Woodcock et al. 2016, Koh et al. 2015). In order to determine whether bee declines are occurring, baseline data or repeated monitoring surveys are required. The lack of comprehensive surveys or monitoring of native bee populations across Montana has resulted in a lack of species lists for the state as well as difficulty in tracking population, species, and community trends. This checklist adds to the basic understanding of native bee fauna, and we hope it will stimulate further research in this important field.
