A Monarchs Reaction in Dark, Heat, or Light

Can Monarchs Survive Different Smells?

Brandon P

What I did was I got five monarch caterpillars and put four in these smells:  Brute, perfume, deodorant, and nail polish remover, and the other in a container with no smell and saw how the smells affected those four monarchs.  The purpose of the experiment was to see how the four smells affected the growth of the monarchs.  I didn't have my results because all my monarchs died except for the one without a smell.  I learned how my monarchs died which was because of the nuclear polyhedrus virus.  Another thing I learned was that the smells slowed them down a lot.  When the one without a smell was in its chrysalis the others were in the second instar stage. 

Can You Turn Off That Light? I'm Trying To Sleep!

Kassy B

My experiment was to find out if fluorescent light on all the time affects the growth of a monarch butterfly.  To perform my experiment I placed two larvae in a habitat under a fluorescent light and one larva in a habitat in a naturally lighted area.  Sometimes I would observe the larva under a leaf, and it was unknown to me whether they were trying to get out of the light.  I learned that the fluorescent light may have affected the growth of the larvae, because the fluorescent larvae were smaller than the natural light larvae.  I learned the time it took for the larvae to emerge from their chrysalises was not affected.

Does The Type of Light Affect Growth?

Kayla B

In my experiment I took 6 monarchs and separated them into 3 containers.  They each had milkweed and moist paper towls on the bottom of the container.  One habitat was next to bright window.  The second habitat was in a windowless room with a 70 watt bulb.  The third habitat was a dark room lit with a black light.  I was wondering if the type of light would affect the monarch larvae's growth.  The natural light monarchs grew the best.  They averaged 8 mm of growth.  Then the light bulb light monarchs grew the next best, with an average growth of 7 mm.  The monarchs in the black light grew the poorest and were the first to die.  They only averaged 2.5 mm of growth.  My caterpillars all died after about 2 weeks.  They became very soft and turned black.  I found out that it could be from a disease called nuclear polyhedrys virus (NPV).  A monarch with this disease would turn black and get gooey.  That is exactly what happened.  I would like to do this experiment again to see what the results would be over a longer period of time.  I wonder if the black light larvae would reach the pupa stage.

How Does the condition of milkweed affect how monarch larvae and butterflies will grow?

Adam W

The purpose of my project was to see how different conditions of milkweed affect how monarch larvae and butterflies will grow.  I put one larva in each container.  I had five larvae and five containers.  I fed larvae frozen, dry, moist, common, and swamp milkweed.  I learned that you shouldn't feed a larva frozen milkweed because there isn't any moisture in it.  Another thing I learned is that some of the larvae might have died from disease.  The first five larvae died.  Two possibly from diseases and three from accidents.  I got three more larvae.  I fed one moist, one dry, and one fresh common milkweed.  In the end, I had two larva that made chrysalises and became monarch butterflies.

In Dark, Light, or Heat

Kayla J

Our project is about farming three different monarch caterpillars in three different conditions with the idea of documenting the beginning, middle, and end results.  Separately and with individual specimens no light, light, and heat were the conditions implemented.  With watchful open minds the conditions were set and the results were written down to be shared with all.  In conclusion, we observed different conditions with very little important effects.  Other than a butterfly not growing one of its wings we reserve the right to draw a conclusion that light was the factor for this outcome.

Should I Stay or Should I Emerge

Kayla P

The purpose of my experiment was to find out if a monarch chrysalis will hatch faster the longer they have been kept in the cold and then brought into a warm environment.  To do this experiment I will wait until one of them forms a chrysalis.  Then I would put it in the refrigerator for one day.  Then I will take it out and put it out on the counter to emerge.  This is what I do with the rest of them except instead of just one day I increase the number of days in the refrigerator by one day for each of the next four caterpillars.  Then I observe them to see which one will emerge first.  I will keep the 6th chrysalis on the table the entire time.  I was not able to complete my experiment because all of my caterpillars died.

The HIghtest Point

Forrest V

Proving my hypothesis was hard because many of my caterpillars died.  I wanted to find out what height the caterpillars preferred to make their chrysalis.  We built four platforms with a  dowel on each one.  Each dowel had four "branches" at different heights.  There was one lower branch, two mid-level branches, and a branch at the top.  Four caterpillars climbed all the way to the top, one stopped in the middle, and two stayed at the lowest level.  The two caterpillars that stayed at the lowest level died.  One died after it made its chrysalis and one before it changed.  The five caterpillars that went to the higher "branches" became butterflies and were released.  I really enjoyed doing this project.

Wet, Dry, or Does It Matter?

Patrick G

The purpose of my experiment was to learn if moisture affected monarch larva.  I put three larvae in different environments:  one wet, one dry, and one just right.  I watched them grow, fed them and studied their movements and growth.  All my larva died, but before they did, they all seemed to grow the same.  One problem with my experiment was that my monarchs kept dying.  Then I finally got three to grow at the same time.  Another uncertainty was if the moisture would affect their pupa, but since they died I didn't get to see that.  I learned that monarch larva don't like to touch wetness and that October is a very hard time to find good milkweed.

What Do Monarchs Drink?

Megan H

   The purpose of this project was to see what would happen if you would feed a monarch Sprite, grape juice, Mountain Dew, and lemonade. We each took two butterflies and experimented with two different drinks.  If we would have been able to work in the same place for our project our results may have been different.We concluded that the monarchs didn't like the Mountain Dew at all while they really liked the lemonade.  The grape juice really affected the monarchs as they were having a hard time walking, their wings were spread out wide, they couldn't fly in their cage any more, and they were very still.  The Sprite, on the otherhand allowed them to act normally with their wings opening and closing and their antennas moving up and down.  They learned that the butterflies like the sweet sugary liquids but not the Mountain Dew.  The Mountain Dew has so much caffeine in it that it could be a possible reason why they didn't like it.  They really liked the lemonade which could be considered more natural.  The monarchs were affected by the grape juice but not the Sprite.  Another thing we learned that the Sprite didn't make them hyper.

What Kind of Drink Do Butterflies Like Best?

Ciarra H, Bailey S

   The purpose of our experiment was to see which type of drink they like the best.  We figured out that butterflies like the coke, gatorade, cherry juice and sugar water but they liked the sugar water the best.  We had three males and one female.

   We found out that butterflies like orange gatorade the least out of all the liquid drinnks we tried.  We also learned that butterflies will drink other liquids besides sugar water.

What's on the Menu?

Feeding Flower Frenzy

   The purpose of our experiment was to see what type of flower the butterflies like the most.  First we put some different kinds of flowers into the container.  Then we recoreded every time a butterfly landed on an individual flower.  Then we put two flowers in at a time in the container.  Our results were that the butterflies liked the Purple Stalks and the White Daisies the most.  One thing that would make our experiment unclear is that we would need more butterflies and different types of flowers to get the results.  Two things we learned were that the butterflies seemed to eat the nectar of the flowers more than the sugar water.  We also learned that the hue of the flower did not matter to the butterflies.

Who Will Emerge First

Ben M

The purpose of this experiment is to observe the development of the monarchs growth.  I set one outside in a container in its natural environment and another inside at a constant temperature.  This way I would find out if the monarch outside would emerge before the monarch inside.  Even though I never found out because they died.  I would have thought the monarch outside would have emerged first.  I thought this because the monarch outside was used to this climate and was in its natural environment.  I didn't think the one inside would emerge first because it wasn't used to the constant climate, and it would need to adjust to this climate.

Will the Monarch Eat Honey or Lemonade?

Michael B

The purpose of my experiment was to see if the Monarch butterfly likes honey or lemonade.  To do the experiment I got two sponges and soaked one with lemonade and one with honey.  The results of the experiment were that the Monarch ate the honey all the time.  When I watched the Monarch he was drinking from the honey sponge.  What might have changed the experiment was to put the honey and lemonade in the cage and watch the whole time.  The Monarch could have been drinking from the lemonade sponge at night when I wasn't watching.  I learned the Monarch likes honey and didn't seem to  be afraid of me.
