Although during that time I was always longing to get back to the water, it was a great experience. I learned so much about ecology, and I got to do some interesting work, including fieldwork in Mexico. You just end up applying everything you learn to your real interests. They are found in many areas in North America. They re in the family Danaidea.
Monarch butterflies are very interesting ecologically.
This family of butterflies is tropical, and does really well in the tropics, but the Monarchs are one of the few species that have also invaded the temperate environment. But to do this, these butterflies maintain a migratory pattern. Most people are familiar with the Monarch butterfly migrations. Opponents are concerned that widespread planting of these crops will unintentionally cause the development of resistance among crop pests to Bt, a commonly used and relatively benign pesticide. In 1999 Cornell University entomologist John Losey performed an experiment in which he dusted Bt corn pollen on plants populated by Monarch butterfly caterpillars, many of which died.
