Results Pollen & Pollinator Results 65 LUREC pollen reference slides created over the summer. 49 pollinators sampled and nearly 100 pollinator observations. Monarch Results 83 Monarch eggs and 25 instars were documented. LUREC’s Monarch waystation was the most productive waystation, while Crystal Lake Park District was the least productive. Over the summer 25 of the 30 eggs brought back to the lab pupated into adult Monarchs and were released outdoors. There were 15 other butterfly/moth species that were observed opportunistically during site visits. An additional 19 Monarchs in the fall were reared and tagged for Monarch watch migration data. Introduction Pollination ecology is a critical element for both food security and maintaining balance in an ecosystem, yet few have conducted analyses of pollination interactions. Many native pollinators including the iconic Monarch Butterfly and the Rusty-patched Bumble Bee have seen populations fall to concerning levels. A pollination study can dictate efficient conservation and restoration practices while also providing data for future evaluation. Our objectives in this project were to: 1) construct a pollen reference slide library of LUREC’s flowers 2) investigate the pollinator-flora relationship found at LUREC 3) begin a preliminary survey of the monarch butterfly activity at five new monarch waystations across McHenry County, IL. Methods & Materials Pollen Grain Slide Sampling: Anthers of identified flowers were place in a vial of around 1.5mL of isopropyl alcohol The solution was vigorously mixed in order to separate anthers from pollen grains One drop of IPA pollen solution was placed at each end of the microscope slide and allowed to dry The gel was created using 35mL of distilled water, 30mL of glycerol reagent, and 10g of gelatin. Half of the gel was stained with 3-5 drops of Safranin stain A small drop of the stained and unstained gel were each placed on a slide cover, put on a slide, and allowed to dry Once set, the slide cover edges were lined with clear nail polish to improve durability and permanency Pollinator Sampling: Pollinators were collected with the use of insect nets or jars from off of identified flowers Both pollen and pollinators were then identified Following pollen removal, pollinators were returned to the wild Monarch Butterfly Monitoring: Each of the five monarch waystations were visited once a week, between 9:00am and 5:30pm, weather permitting Milkweed plants at each site were checked for any monarch activity Time spent at each site depended on the size of the patch and the number of milkweed plants The monarch eggs, and first, second, and third instar caterpillars were brought back to the laboratory so as not to be predated A video was created and posted to Loyola University Retreat and Ecology Campus Facebook page Conclusions 1. The creation of a reference pollen grain database for plant species found at LUREC combined with the knowledge gained from sampling pollinators provides valuable information for appropriate management of the grounds. 2. While conducting research, we happened to find, identify and photograph on four separate occasions a Rusty Patched Bumble Bee, a newly listed endangered species. 3. This was the first year that monarch butterfly data was collected at the identified waystations. Our data will be useful for future researchers studying the population of monarchs in the area.

● 83 Monarch eggs and 25 instars were

documented.

● LUREC’s Monarch waystation was the

IntroductionPollination ecology is a critical element for both food security and maintaining balance in an ecosystem, yet few have conducted analyses of pollination interactions. Many native pollinators including the iconic Monarch Butterfly and the Rusty-patched Bumble Bee have seen populations fall to concerning levels. A pollination study can dictate efficient conservation and restoration practices while also providing data for future evaluation.

Our objectives in this project were to:1) construct a pollen reference slide library of LUREC’s flowers2) investigate the pollinator-flora relationship found at LUREC3) begin a preliminary survey of the monarch butterfly activity at five new monarch waystations across McHenry County, IL.

Methods & MaterialsPollen Grain Slide Sampling:● Anthers of identified flowers were place in a vial of around

1.5mL of isopropyl alcohol● The solution was vigorously mixed in order to separate anthers

from pollen grains● One drop of IPA pollen solution was placed at each end of the

microscope slide and allowed to dry ● The gel was created using 35mL of distilled water, 30mL of

glycerol reagent, and 10g of gelatin. Half of the gel was stained with 3-5 drops of Safranin stain

● A small drop of the stained and unstained gel were each placed on a slide cover, put on a slide, and allowed to dry

● Once set, the slide cover edges were lined with clear nail polish to improve durability and permanency

Pollinator Sampling:● Pollinators were collected with the use of insect nets or jars

from off of identified flowers● Both pollen and pollinators were then identified● Following pollen removal, pollinators were returned to the wildMonarch Butterfly Monitoring:● Each of the five monarch waystations were visited once a week,

between 9:00am and 5:30pm, weather permitting● Milkweed plants at each site were checked for any monarch

activity● Time spent at each site depended on the size of the patch and

the number of milkweed plants● The monarch eggs, and first, second, and third instar

caterpillars were brought back to the laboratory so as not to be predated

● A video was created and posted to Loyola University Retreat and Ecology Campus Facebook page

Conclusions1. The creation of a reference pollen

grain database for plant species found at LUREC combined with the knowledge gained from sampling pollinators provides valuable information for appropriate management of the grounds.

2. While conducting research, we happened to find, identify and photograph on four separate occasions a Rusty Patched Bumble Bee, a newly listed endangered species.

3. This was the first year that monarch butterfly data was collected at the identified waystations. Our data will be useful for future researchers studying the population of monarchs in the area.
