Location: Marsh Haven Nature Center, on Hwy 49, three miles east of Waupun
Fond du Lac County
Although quite breezy, butterfly activity was very productive once I got behind the main building. I also easily found three Monarch Caterpillars in the two minute time frame that I looked for them. I was restricted to the trails because of NUMOROUS black and yellow spiders in their large orb webs (not the common Garden Spiders that I'm used to).
