Kids Know Nevada Insects: Monarch Butterfly
I am the monarch butterfly! I am found all throughout the United States and even southern Canada. I am most well-known for the yearly trip back and forth (called a migration) that I make every fall and spring. Monarchs in Nevada and other western states head to the coast of California, but those in the east head all the way to central Mexico. When we arrive, we hang from trees in big numbers, waiting until spring to head north. We do this to avoid cold weather, returning in spring when the plants we need begin to grow again.

Know Nevada Insects: Monarch Butterfly
The monarch butterfly is perhaps one of the most iconic butterfly species in North America, and it can be found throughout Nevada in the summertime. This species is famous for its yearly migration. Unlike Eastern U.S. monarchs that migrate to central Mexico, our Nevada monarchs migrate hundreds of miles to the coast of California every winter, returning back north to breed on milkweed plants.

Soil Properties, Part 2 of 3: Biological Characteristics
