Bee Blitzes across Ohio during National Pollinator Week, June 16 – 24

Join Denise Ellsworth from the OSU Bee Lab along with fellow bee enthusiasts at one of these Bee Blitz events across Ohio during National Pollinator Week, June 16 – 24.

Volunteer seed collectors needed in Ohio!

Pollinator Partnership (P2) is seeking volunteers to participate in the Ohio portion of their Monarch Wings Across the Eastern Broadleaf Forest project. Volunteers work with seed collection teams to collect seed from 20 targeted monarch host and nectar plant species. 

P2 and partners will be holding a training in Summit County (Akron area) on Thursday, May 31st from 9:00am-noon. If you are interested in becoming trained and assigned to a collection team, please register today. Registration is open through Friday May 25th.

If you are located within the EBF-CP, but cannot attend the in-person training, and would like to learn about other ways you can get involved with this conservation project, please email Amber Barnes ( Other states also have P2 seed collection projects for those interested outside the buckeye state.

Once volunteers have completed the training, the State Lead in Ohio, Annie Rzepka ( will be in touch and assign volunteers to a collection team. The teams are located throughout northern, central, and western Ohio, following the Eastern Broadleaf Forest-Continental Province (EBF-CP) ecoregion. For more information about this project and a map of the seed collecting regions of Ohio, please visit P2’s webpage at This screenshot shows the Ohio counties included in this project:

Intensive weekend Bee Course with bee expert Olivia Carril, coming to Ohio 6/1 – 6/3

Join Olivia Carril and Denise Ellsworth at The Arc of Appalachia from June 1 – June 3 for The Bee Course, a workshop on the ecology, natural beauty, identification, and conservation of Ohio’s pollinators. Emphasis will be on enjoying close-up encounters in the classroom and  in the field to meet some of Ohio’s 500 species of bees – including the largest bumblebees, the smallest sweat bees, leaf-cutting bees and mason bees. The weekend will include ideas you can apply at home to attract and sustain pollinators in your home and gardens. 

Olivia Carril is the Author of, the Bees in Your Backyard: A Guide to North America’s Bees and has been studying bees since she was 18 years old. She completed a Masters degree in 2006 at Utah State University, establishing a long term ecological study of the environmental factors influencing bee diversity on the Colorado Plateau.  In 2013 she received her PhD from Southern Illinois University Carbondale, studying a specialist bee (Diadasia) and its host flowers (Mallows and Cacti).  

Denise Ellsworth directs the honey bee and native pollinator education program through the Ohio State University Department of Entomology. In this outreach position, Denise supports and teaches beekeepers, farmers, gardeners and others across the state through a variety of workshops, webinars, written materials and electronic resources. 



Workshops coming to Ohio: Bees in Your Backyard with Olivia Carril

Learn from bee expert Olivia Carril at one of three day-long native bee workshops. This year’s “Bee Tour” will focus on practical ID in the field, using cameras or phones to capture images, and citizen science for everyone. We’ll practice hands-on bee identification through microscopes and exploration in the field with Olivia and a team of biology experts.

Workshops: June 4, 5 and 7, various locations. All sessions are 9AM to 4PM.

Monday, June 4th: Stratford Ecological Center,  Delaware

Tuesday, June 5th: The Dawes Arboretum, Newark

Thursday, June 7th: The Huston-Brumbaugh Nature Center of the University of Mount Union Minerva

Help Hunt for Queen Bumble Bees! New Citizen Science program through the Goodell Native Bee Lab at OSU

Rusty patched bumble bee USGS Bee Inventory and Monitoring Lab

The Goodell lab is looking for volunteer naturalists who are able to identify bumble bees to species to help collect data on nest-hunting and foraging queen bumble bees this spring (April – June). This is part of a 2017-2018 statewide Ohio bumble bee survey that is being conducted by Karen Goodell’s lab at Ohio State and Randy Mitchell’s lab at the U of Akron, and is funded by the Ohio Department of Transportation. The primary goal is to determine the current distribution of the endangered rusty-patched bumble bee and the yellow-banded bumble bee, a species of concern. Secondarily, this survey will provide the opportunity to learn more about the distribution and habitat use of common species as well. 

 Volunteers will collect data and report on:

(1) information on nest-hunting bumble bee queens

(2) timed 15-min observations of patches of flowers where queens forage

Find details and data collection forms here.

Looking for 2018 Bee Survey Sites in Select Ohio Counties

We need your help! Can you suggest possible survey sites in Ohio? Ideally, locations would be 1-3 acres (or more) in size, and be full of flowers in summer (meadow, prairie). A patch of woods nearby is a plus. These can be public or private lands.
Counties in need for the 2018 bee survey are in gray. Counties in purple with black dots indicate areas surveyed in 2017. Dotted lines encompass areas with historical sightings of the rusty patched bumble bee, so sites in those areas are of particular interest.
To suggest a survey location, visit:

Everyone can help by joining the Ohio Bee Atlas project on iNaturalist. Upload your bee images to the project — you don’t have to ID the bee to participate! Learn more here.
