About this lesson
The “Bee Germs” project is focusing on learning more about bees that live underground. We know very little about bees that make their homes underfoot; by learning more about their germs (or pathogens) we will be able to understand what diseases they are suffering from and, eventually, find ways to help them.
Where can I find nests?
Nest locations geographically
Ground nesting bees can be found everywhere in the US.What diseases do they have?
Examples of some known diseases
Nosema, Crithidia, and AscosphaeraDownloads

Why should we care about this project?
European Honeybees (Apis mellifera) get most of the credit for pollinating our crops, but they aren’t the only bees out there doing the work. Historically they’ve been responsible for a large potion of the pollination of our crops, however die-offs (like colony collapses) of the honey bee in North America and Europe have brought attention to the bees we depend on for our food. It’s not just European honey bees doing the work; there have been native and managed (like with a beekeeper in a man-made hive) bees working diligently to pollinate our crops all along.
In this lesson plan, you will learn how to find and collect native bee pollinators that are abundant in the springtime. Bees collected with this protocol will be used to quantify pathogens and understand how much diseases are affecting native bee pollinators in North America. Learning about where these bees live and what pathogens they have could help us provide more suitable habitat for them and help them fight off diseases. We want them to thrive, after all, so this project helps researchers learn more about the germs they carry with them.
Native bees and their pathogens
What are native bees?
Bees are key species for ecosystem function because their roles as pollinators of plants, including most of the fruits and vegetables we eat. There are more than 4,500 species of bees in North America, and over 20,000 around the world. However, the basic biology and diseases of most of these bee species is unknown and we want your help to find out more about them.

One of the easiest ways to tell the difference between the two types of pollinators in the US is to look at their pollen pockets.
Native bees are bees from the place where they are still found. The common honey bee (Apis mellifera) is the most popular bee for pollinating our food crops in the United States, but she is originally from Europe.

Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
LS2.A: Interdependent Relationships in Ecosystems
- Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.
