Mason Bees

Mason bees, one of the earliest spring bees in Minnesota, are out pollinating in full force. In contrast to most other solitary bees, mason bees spend the winter as adults in cocoons.  This allows them to emerge earlier in spring than many other bees that overwinter as larvae and still need to pupate before emerging as an adult.

Mason bees get their common name from the habit many have of lining and sealing their nests with mud.  In spring, a single solitary female mason bee will start building a nest in an empty cavity like a hollow stem, beetle burrow, or hole in the ground.  Starting at the back of the hole, she will place a ball of pollen, lay an egg, and then seal off the chamber with mud or chewed leaves.  She will continue this way until the entire tunnel is full.

There are 30 species of mason bees (genus Osmia) in the eastern United States and Canada.  Of those, 15 species are likely to be found in bee blocks in Minnesota. Female mason bees use the hairs on the undersides of their abdomens to collect pollen from willows, maples, plums, Virginia waterleaf, wild geranium, and other spring wildflowers.  They will then bring the pollen back to the nest to provision cells for their offspring.

Mason bees are commonly used to pollinate agricultural crops like apples, cherries, and plums due to their early spring activity and the ease of providing artificial nests.

For more information on mason bees, look for "Bees: An Identification and Native Plant Forage Guide" by Heather Holm or "The Bees in Your Backyard" by Joseph Wilson and Olivia Messinger Carril.

City Nature Challenge 2017: Update

The 2017 City Nature Challenge is coming to a close. Over the past four days, people from all over the country have been using the iNaturalist platform to make observations and identify species in various cities around the the nation. As of today, 88343 observations have been made with 7093 species IDs and 3410 participants.

In the Minneapolis/St. Paul Metro Area, over 800 observations where made. You can find more information about the iNaturalist statistics for all the participating cities here.

Below are some of the images taken from the Minneapolis/St. Paul iNaturalist page! Thank you, everyone who took part in this year's challenge.

Introducing the Naturalist, a new podcast from Extension

On the Naturalist, we set out to explore the world of Minnesota natural resources, all while capturing great stories and talking to people about the environment. Produced in-house by the FWCE team. Let us know what you think! 


Episode 1 - Boulder Lake Environmental Learning Center and EAB 

For this episode, we get a chance to talk to John Geissler and Nick Wagner from Boulder Lake Environmental Learning Center about the challenges associated with running an 18,000-acre center with a two person staff. Also, we talk to Angela Gupta, an Extension Educator/Forester, about a pest by the name of Emerald Ash Borer and the potential impacts it can have on Minnesota's forest.

City Nature Challenge: Minneapolis/St. Paul

Which city in the United States has the most nature? The City Nature Challenge 2017 (April 14-18) will help us find out!

Just in time for National Citizen Science Day (April 15) and Earth Day (April 22), 16 U.S. cities are asking residents of and visitors to these urban areas to explore nature all around them and document the species they find. It all starts on Friday, April 14th and runs through Tuesday, April 18. Not only will these observations help build up the baseline of Minnesota biodiversity, but it also provides data for our local scientists, land managers, and governments about the areas they study and care for.

Who will come out on top? Which city will have the most species found, the most observations, the most citizen scientists involved?

University of Minnesota Cooperative Extension firmly believes that this challenge is something all Minnesotans can get behind. Let us show the rest of the nation what Minnesota biodiversity is all about!

So what can you do to help the Minneapolis/St. Paul Metro Area win this challenge?

The absolute easiest way is to download the iNaturalist app on your phone and to make observations of any and every living thing: species you find in your backyard, in your favorite park, on your walk to school or work. Any observation made within the Twin Cities and the surrounding counties between April 14th and April 18th will count toward the Minneapolis/St. Paul Metropolitan Area. The great thing about using iNaturalist is that you don’t need to know what it is you’re documenting - you just need to take good enough photos that someone else in the iNaturalist online community can ID it for you! More information can be found on iNaturalist’s Getting Started page. Starting on the 14th, you can see your observations and others made in the Metro Area for the challenge here: City Nature Challenge 2017: Minneapolis/St. Paul.

If you’re familiar with Minneapolis/St. Paul flora and fauna, you can also help by adding identifications to other people’s observations on iNaturalist.

You can also participate in one or more of the events being held in the Metro Area during the week of the competition. These events are designed to bring people together to learn more about our local nature, try out iNaturalist, and make nature observations as part of the City Nature Challenge. Check the City Nature Challenge 2017: Minneapolis/St. Paul page for upcoming events.

We look forward to seeing what you find in the Metro Area during the City Nature Challenge!

Sharing the Spotlight: Native Bees

As spring nears, you may start to see headlines like "10 Amazing Facts About Bees!" or "How to Attract Bees to Your Garden."  These articles and the photos in them almost always refer to honey bees.  Although they are an important and charismatic part of our agricultural system, honey bees are not native to North America.  With an estimated 400 different species of native bees in Minnesota, we think they deserve their own list of amazing facts.

1.  Bees in Minnesota show tremendous diversity, ranging in size from small sweat bees to large bumble bees.  They may be black and yellow striped like cartoon bees but can also be green, orange, or metallic blue.
2.  Most Minnesota bees are solitary, meaning they do not nest with other bees and do not share responsibility for maintaining a hive or colony.
3.  Many bees spend most of their life as larvae or pupae and may only be active as adults for a few weeks of the year.  You probably have many bees in your yard that you've never noticed.
4.  Bumble bees, as well as a few other bees, use a process called "buzz pollination" to shake pollen from hard-to-reach flowers like those in the family Solanaceae. By vibrating their flight muscles at a particular frequency, they are able to shake the pollen off the flower.  You can see buzz pollination in action in this video.
5.  None of the bees native to Minnesota make honey.  Bumble bees may store 1-2 days worth of nectar in “honey pots” in case of poor weather or other events that may prevent them from foraging but they do not make honey from the nectar.
6.  Some bees are kleptoparasites meaning that instead of building their own nests and providing food for their offspring, they lay their eggs in the nests of other bees.  This isn't altogether unusual in the animal kingdom; cowbirds are also known for this behavior.

Audience members who contributed to the development of the curriculum stand and receive recognition.

The first Minnesota Master Naturalist Program North Woods Great Lakes course was taught in Duluth in 2008, making the Great Lakes Aquarium an appropriate venue for the premiere of the latest curriculum book, North Woods, Great Lakes: An Introduction to the Natural History of Minnesota’s Coniferous Forests. Hundreds of Master Naturalist volunteers have since completed the course, graduating into service to promote awareness, conservation, and understanding of Minnesota’s natural environment in their communities.

Keynote speaker, Kurt Mead, took the podium later in the night. As a Department of Natural Resources interpretive naturalist at Tettegouche State Park, Kurt contributed to the development of the NWGL curriculum and worked with various Master Naturalist volunteers over the years. During his presentation, Kurt described t the characteristics that make Minnesota’s North Woods, Great Lakes biome unique and fascinating.

Over three-thousand participants have completed the statewide Minnesota Master Naturalist program since its inception in 2005. Master Naturalist volunteers have contributed over four hundred thousand hours service through stewardship, research, and education impacting over 3.4 million acres of Minnesota’s natural resources. The NWGL curriculum has received wide recognition as a quality resource for learning about natural history and ecology in the region. The February premiere was a celebration of all that the program has been able to accomplish. It was a way to get people together to discuss their Master Naturalist stories and share the experiences that have led to the success of the program.
