Bee collectors needed for The Ohio Bee Survey in select Ohio counties

The Ohio Bee Survey is a new OSU project that aims to inventory the richness of Ohio’s wild bee species over two years. We are recruiting volunteer bee collectors who will set out and collect small bee bowls once a week for 21 weeks from May through October. The weekly catch will be frozen, then delivered or mailed to a central locations for pinning and identification later in the year.

Our goal is to have at least one bee collector in each county. We began recruiting bee collectors in the last two weeks, and now have good coverage in many areas across the state. However, we still have about 30 counties without a collector (see list below).

Supplies and training materials are all provided by U.S. mail to collectors. Bee collectors can be Master Gardeners, OCVN volunteer naturalists, OSU employees or others not affiliated with OSU. Collection areas can be in home landscapes, farms or gardens, so travel is not required. (Specific locations such as parks may have permitting requirements, but there are not overall permitting requirements to participate).

Small painted bowls are filled with soapy water, left in the landscape for 24 hours, then collected, strained and the contents frozen. Collection happens alone, so collectors can easily comply with social distancing requirements.

If you or someone you know in a county below would like to participate in the survey, please visit this website:

Free Bee and Wasp Cards to Celebrate National Pollinator Week

Ohio is home to more than 450 species of bee. They’re bumble bees, carpenter bees, cuckoo bees and others, and you can identify more than a dozen of them — types you’re likely to see in your garden — using the pocket bee card from The Ohio State University.

And how about some love for wasps? Ohio has an amazing diversity of wasps, including paper wasps, golden digger wasps and potter wasps. Not fond of wasps? They serve as pollinators, are important in the biological control of caterpillars and other pests, and add to the diversity and beauty of our landscapes.

To celebrate National Pollinator Week, The OSU Department of Entomology is offering a free copy of the 4-by-6-inch bee and wasp identification cards. Common Bees of Ohio and Common Wasps of Ohio cards can be requested through July 5th by sending a self-addressed, stamped, business-size envelope to “Bees and Wasps” c/o Denise Ellsworth, OSU Entomology, 1680 Madison Ave., Wooster, OH 44691. One copy of each card will be sent per envelope.

Multiple copies of the bee and wasp cards can be purchased through the OSU Extension Publications website.

Free copy of Botany Primer: join us for the USA Phenology Network webinar

Hello! As a reminder, LoriAnne Barnett of USA National Phenology Network will host a webinar on April 23rd at 11AM (60m) for anyone interested in Nature’s Notebook training. This training will orient cooperators who are planning or might be interested in using Nature’s Notebook to collect phenology data. LoriAnne will be sharing a tip sheet on data collection, and will answer questions about how to customize data collection for goals your site may have. She will also share details about the on-line phenology short course and other advanced training offered by NPN this year.

As a thank you, webinar participants will get a free hard copy of the popular Botany Primer!

Please contact LoriAnne to register for this webinar. I hope you can join us on the 23rd!

Phenology updates, spring 2019

Bumble bee phenology: look for queens flying when Virginia bluebells flowers.

Hello phenology fans! I wanted to let you know about some changes happening this year with the OSU Phenology Garden Network…..but first, I want to thank our many amazing volunteers and cooperators.  Our volunteers have done everything including installing gardens, collecting data, hosting educational phenology programs for the public, observing pollinators and even relocating gardens as they outgrew their spaces. I want to thank everyone who has been an enthusiastic partner — particularly those who have been involved with the project since its inception in 2004! Together we have helped thousands of people gain an appreciation for phenology.

If you’re like me, phenology has changed your outlook and your life! There’s no “unseeing” nature’s sequence once you focus your lens. I feel fortunate for the privilege to work with so many dedicated volunteers over the last 15 years. Thank you so much!

  • I hinted last year that changes would be coming to the plant data collection effort. As of 2019, OSU will no longer be collecting plant phenology data. The USA National Phenology Network has agreed to archive the OSU Phenology Garden Network data. If your site would like to continue to observe and gather plant phenology data, I recommend that you link with the USA National Phenology Network’s Nature’s Notebook program.  They will also provide training to sites interested in collecting phenology data through Nature’s Notebook. Lorianne Barnett of NPN will host a webinar on April 23rd at 11AM for anyone interested in Nature’s Notebook training. About a third of the OSU Network plants are on the Nature’s Notebook site, and more can potentially be added. Please contact Lorianne to register for this webinar.
  • Of course, your phenology garden can continue on however it makes sense at your location whether or not you decide to collect and submit data through Nature’s Notebook or The Great Sunflower Project.
  • Some garden sites have transitioned to include pollinator habitat demonstration. Thanks to a Pollinator Health grant, we are again able to provide flats of native perennials for educational or demonstration sites across the state. These can be phenology garden sites, but could also be other public demonstration sites not formerly part of the OSU Phenology Garden Network. This year, we have flats of native perennials used by specialist bees (4 plants each of 8 different species from the list below). We can also provide up to three flats (32 plugs each) of common milkweed Asclepias syriaca for educational/demonstration use (not private lands/gardens). These plants will be available for pickup at Secrest Arboretum on May 2nd from 10AM to 12 Noon. We will gather in Miller Pavilion to have a short program, distribute plants and take a phenology walk in the arboretum with Dan Herms. Register here to reserve plants to pick up on May 2nd! 

We will also have a limited number of tall metal plant markers for sale $4 each on May 2nd (bring a cash or a check made payable to Lora Avens). Reserve markers on the “reserve plants” link above.

Native perennials for specialist bees. This is our master list of plants we’re growing for demonstration and habitat projects, including making bee observations through The Ohio Bee Atlas project on iNaturalist:

Ratibida columnifera, upright prairie coneflower

Ratibida pinnata, pinnate prairie coneflower

Solidago nemoralis, gray goldenrod

Solidago rigida, stiff goldenrod

Solidago speciosa, showy goldenrod

Symphyotrichum leave, smooth blue aster

Symphyotrichum lateriflorum , calico aster

Symphyotrichum novae-angliae, New England aster

Vernonia fasciculata, prairie ironweed

Veronicastrum virginianum, culver’s root

Zizia aurea, golden Alexanders

Be sure to let me know what questions you have, and thanks again for sharing your time and talents with the OSU Phenology Network, whether you’re a recent or long-time cooperator!

Best wishes for a warm, sunny spring,


Native Perennials for OSU Phenology Garden Network sites

Yes, we have more plants available — up to 5 flats– for your OSU Phenology Garden Network site! Phenology Garden sites are receiving first notice of this offer, going out to Extension offices today.

Thanks to a NIFA IPM grant for pollinator health and an amazing grower (Bob Filbrun at the OARDC Muck Crops branch), the OSU Bee Lab’s “Partners for Pollinators” project ( is able to provide native perennial plugs (3″ containers) for OSU pollinator-related research and demonstration projects. Do you have an existing pollinator/phenology display garden or research plot you’d like to expand? A new pollinator outreach project you’d like to develop? A citizen science monitoring effort, or another good public use of native perennial plants to help pollinators?

We have nearly two dozen species of native perennials available, including milkweed, aster, liatris, lobelia, rattlesnake master, wild bergamot, mountainmint and many more. You can mix flats at pick-up (most plants are in 4-packs, with 32 or 72 plants to a flat) to create garden diversity. We also have rooted cuttings of native shrubs, including staghorn sumac, buttonbush, dogwood and willow.

Each project request can receive up to 5 flats of plants. 

To request plants, please complete this form, including total number of flats requested and intended location and use. 

Flats must be picked up on June 28th between 11AM and 2PM at OARDC in Wooster near Thorne Hall (details will be e-mailed) by an OSU employee or affiliated (phenology) volunteer. Selection is on a first-come, first-served basis. 

Plants can only be used for OSU (including OSU partner) pollinator educational, display or research projects: no home plantings, and no resale. Recipients agree to follow up with photos and brief use of site details for pollinator events, displays or programs. Quantities are limited, so make a request ASAP!

Thanks for helping the bees,
