The Xerces Society hosts webinars and participates in events organized by other organizations. This page lists all the upcoming topics and dates. You can also find updates on our social media and via our enewsletter.


Please note that we are accepting remote speaker requests! Depending upon our capacity, we can provide talks through platforms such as Zoom and Google Hangouts. Please fill out our speaker request form here.


We also encourage you to subscribe to our YouTube channel. Webinars put on by Xerces will be uploaded here after their stated calendar date, and there are many other resources available on our channel, including the Xerces Classroom Series.

March 7
1:00 PM - 2:00 PM PT/ 2:00 PM - 3:00 PM MT/ 3:00 - 4:00 PM CT/ 4:00 PM - 5:00 PM ET

Mormon crickets and grasshoppers are an important part of western grassland ecosystems, supporting the food needs of dozens of bird species such as the declining American Kestrel and Western Meadowlark. Yet public lands in the Western United States, especially in Montana, Wyoming, and Oregon, are frequently sprayed with pesticides to kill these important native insects.

Join American Bird Conservancy (ABC) and the Xerces Society for Invertebrate Conservation on March 7th at 2pm MT/4pm ET to find out how this program impacts important bird prey like caterpillars and beetles. ABC's Hardy Kern and Xerces' Sharon Selvaggio will discuss how conserving habitat for beneficial invertebrates, as well as birds and other grasshopper predators, is part of the solution for keeping grasshopper populations manageable.


  • Hardy Kern, Director of Government Relations, Birds and Pesticides Campaign, ABC
  • Sharon Selvaggio, Pesticide Program Specialist, Xerces Society

Sharon Selvaggio - Pesticide Program Specialist - Xerces Society
Sharon assists Xerces staff, partners, and the public to reduce reliance on pesticides and understand pesticide risk to invertebrates. Sharon previously worked at Northwest Center for Alternatives to Pesticides, the U.S. Fish and Wildlife Service, and the U.S. Forest Service, and integrates her focus on pesticides with her experience managing natural areas and agricultural lands. Sharon earned a Master of Science in energy and resources and a Bachelor of Arts in biology, both from the University of California, Berkeley. Sharon spends a lot of time in her vegetable garden, which has an always-buzzing insectary/pollinator patch, and she is a frequent visitor to the Pacific northwest's wildlands for recreation

Mar 28
10:00 AM - 11:00 AM PT / 11:00 AM - 12:00 PM MT/ 12:00 PM - 1:00 PM CT/ 1:00 PM - 2:00 PM ET

Join Rich Hatfield, Xerces Senior Endangered Species Conservation Biologist, to take a deep dive into the reproductive females of bumble bees, including cuckoo bumble bees. We'll primarily look at the solitary phase of the lifecycle, including what is known about where and how they hibernate, and what we know about what it takes to establish a nest and how they select a site. We'll likely have as many questions as answers in this webinar, but please join us for an exploration into the lesser known aspects of bumble bee ecology.

This webinar will be recorded and available on our YouTube channel. Closed Captioning will be available during this webinar.

Rich Hatfield - Senior Endangered Species Conservation Biologist, Bumble Bee Conservation Lead - Xerces Society
Rich manages all aspects of the Xerces Society’s work on bumble bees. Rich has a master’s degree in conservation biology from San Francisco State University, and he joined the Xerces Society in 2012. While earning his degree, his thesis focused on local- and landscape-level factors that contribute to bumble bee species richness and abundance. He has also investigated native bee pollination in agricultural systems in the Central Valley of California and researched endangered butterflies in the San Juan Mountains of Colorado, as well as throughout the Pacific Northwest. In addition to his skills as a research biologist, Rich also has extensive classroom teaching experience with a focus on conservation biology, ecology, and sustainability.
