Early Springs, Monarch Killer?!?

Kevin W, Evan V

We wanted to know that if earlier springs came, would monarchs adapt and come earlier or would they come at the same time and risk the milkweed becoming senescant. So we took data from We first saw if the milkweed is coming earlier then usual. It was. So then we counted the gap between the first observed milkweed and the first egg at a specific site ranging from Minnesota to Missouri. We then took the average of all the sites and found that the gap is getting bigger and that monarchs are not coming earlier even though the milkweed was.

How do temperature and humidity affect monarch populations?

Eric V

I wanted to know how climate conditions affected a local monarch population. I used population and temperature and humidity data from Stoney Ridge Farm dating five years back. After putting it in spread steets and putting it into "R" I found that humidity drastically affects monarch populations.

How does your Garden Grow?

Meghan M, Grace A

In our experiment we wanted to figure out what plants to plant in our garden that would help the monarchs in the late summer/fall. We put monarchs into a pop-up cage with purple asters and white asters. We recorded how many times the monarchs nectared or visited the flowers. We discovered that the monarchs prefered the purple asters the best.

Light Days Dark Nights

Emily S

In my lab I wanted to see if light affected the time that the monarch came out of, eclosed from, his/her chrysalis. I started with 3rd instars monarchs. Then I put 5 of larvae into 3 containers then labled one dark, one partial light, and one full light. I fed everyone of the monarchs the same kind and amount of milkweed. Then when they started forming their J`s I* waited. The result was that the monarch from the partial light containar eclosed first!

Monarch Density: Garden Vs. Prairie

Chris M

What I wanted to know was if habitat status, such as nurtured garden or restored prairie, would effect the monarch density. I gathered data from the MLMP database, collecting data from multiple sites. To determine the monarch density, I found the quotient of total eggs and milkweed found per site. Eventually, after running a T-test with the program "R" to determine significance, I found that there was no significant difference in monarch density between nurtured garden and restored prairie habitats.

Mysterious Milkweed

Justine N, Jordan P

We wanted to know what type of milkweed monarchs preferred. For our experiment we used common milkweed, swamp milkweed, and whorled milkweed. We put the milkweeds in the cage and put the monarch caterpillers in the middle. We waited for at least five hours. We discovered the monarchs preferred the swamp milkweed, but the numbers were so close that we couldn't say they preferred one type of milkweed.

Mystical Monarchs

Josh P, Wyatt A

In our experiment we wondered if a monarch pupates at a different rate with different temperatures. We had two coolers holding tubs with monarchs and a box with another tub of monarchs. We had temperatures that were hot,cold,and room temperature. We found that the monarchs reared in heat pupated faster. Also we found out that cold stunted them the most. We would need more trials to say that a hot enviroment is better. Many larvae were infected by a bacteria and some OE.
