BIML Lab Summary of U.S. Bombus Captures in 2010 and a comparison with 2009
This past year the BIML lab was involved in a number of bee projects throughout the U.S. One in National Parks on Climate Change in Dune and High Elevations, another pilot project in National Forest and Range Experiment Stations to investigate using glycol traps for monitoring. As part of those studies a fair number of bumblebees were captured and given the current interest and concern over this group I thought it would be useful to document a bit what was captured.
We spent quite a bit of time working on identifications within this group and comparing our determination with the specimens at the National Collection, but given that our traditional realm is East of the Mississippi there are perhaps some misidentifications and thus we welcome questions and are happy to send specimens that you may have questions about.

Many thanks to the network of collaborators, researchers, and naturalists who contributed to these records. Each of you can clearly see the impact you had from the tallies by state and species. Without your help very little would be know about Bombus or other species in North America.
Note that this coming year we will be expanding the glycol trap system with a 5 year test of at least 25 USFS sites across North America as well as working in about twice as many National Parks as well as some scattered work in FWS refuges and other locations.
