2 WI Bumble Bees Need Your Help WI has 20 bumble bee species. 1 is federally endangered. 7 are state species of greatest conservation need. 3 are state species with information needs.

3 B3 Mission To improve our understanding, management, and conservation activities related to Wisconsin bumble bees.

4 B3 Long-Term Objectives Develop an accurate map of species distributions Identify species-habitat associations Assess habitat conditions and determine conservation threats Determine baseline population status and monitor trends over time

5 Wisconsin bee diversity: Wisconsin Bumble bees 85% are solitary bee species 15% are Social or semi-social bees 400 (to 500) Wisconsin native bee species Social, perennial, European Honey bee: 1

6 Biology Social (queens, workers & males), annual colony Wide variety of habitats Most diverse in temperate & montane areas WI active mid April early October (varies by species) Very hairy bodies, active early & later in day Buzz pollination

7 Biology Corbicula pollen carrying structure

8 Biology A queen emerges from hibernation in spring and finds a nest site, such as an abandoned rodent burrow. In autumn the colony produces new queens and male bees, who leave to find mates. Newly mated queens hibernate and the rest of the bees die. She creates wax pots to hold nectar and pollen, in which she lays and incubates her eggs. When her daughters emerge as adults, they take over foraging and other duties

11 Cuckoo Bumble Bees 5 species in WI Social parasite, no corbicula on hind tibia Parasitize nests of other species Nicole Shutt Fernald Cuckoo Lemon Cuckoo Indiscriminate Cuckoo

12 Cuckoo Bumble Bees Very rare (possibly extirpated) from WI No recent records in WI Ashton Cuckoo Carlos Vergara Variable Cuckoo

13 Commercial Bumble Bees Tomatoes Peppers Squash Strawberries Blueberries Cranberries

14 Things Bumble Bees Need Nesting Habitat Floral Resources Overwintering Habitat Water

15 Habitat: A bee s eye view Native plant gardens with diverse, abundant floral resources; suitable nest sites, late season flowers and overwintering sites; no insecticides, especially systemic ones.

18 Photography-Based

19 Two Ways to Contribute Incidental observations are casual or unplanned sightings Small area surveys are conducted when you purposefully look for, photograph, count, and record the bumble bees that you see at a single location, following the guidelines in this manual.

20 Small Area Surveys Record basic survey information Stay within a 30m diameter area (or less) Count the number of bumble bees of each morph that you see Photograph at least one bee per morph Record number of bees, presence of queens, presence of nests, & photo names on Data Sheet Curate photos Summarize data on Summary Sheet Submit data online

21 Small Area Surveys- Where & When Site: general location, anywhere with blooming plants Survey location: specific area you survey (30m diameter or less)

22 Small Area Surveys- Where & When Small site: survey space available in the 30m diameter Large site: multiple surveys 100m apart

23 Small Area Surveys- Where & When April/May-October Avoid rain, high winds, and severe weather Easier to photograph when cool

24 Small Area Surveys- Tallying Morphs Count the number of individuals of each morph seen Morphs are visually distinct groups based on Color patterns Size Number of abdominal segments (males 7, females 6) Presence of corbicula (pollen basket) on legs

48 Photography Tips Camera type point & shoot, DSLR & phone cameras (>=8 megapixels) Experiment with your camera macro setting, auto exposure and auto focus might be best Be calm, while the bees are nectaring and/or collecting pollen, you can be quite close without disturbing them.
