Eggs, eggs, eggs galore!

Ellery K

I wondered if the type of milkweed affected the number of eggs a female monarch laid. I placed 4 different types of milkweed (whorled, common, tall and swamp) in a large screened cage. I placed 4 female monarchs that had mated in the cage for one week. I found out that the monarchs preferred to lay the most on the tall milkweed (173 eggs). They laid the fewest on the common milkweed (39 eggs). I think one of the reasons that they laid more on the tall milkweed was because it had thinner leaves and flowers. The common milkweed did not have flowers. Next time I would like to study if they lay more eggs on the top or the bottoms of the leaves.


Soaring High with Dragon Flies!

Nani K

I wondered if the type of lake site, urban or rural, would make a difference in how many different species of dragonflies I could catch. Over the summer of 2013, I caught 7 different species of dragonflies at an area around Lake Harriett and 15 different species by the Lake near my cabin in North Western Wisconsin. In the summer of 2014, I caught 13 different specie of dragonflies by Masterman Lake. I found about the same number of species at the lake near my cabin in 2013 and Masterman Lake in 2014. These findings support my first hypothesis. Although I did find more species at Stone Lake and Masterman Lake there might be other reasons I caught more at these two lakes.
