Monarch butterflies(帝王蝶) are flying through Missouri(密苏里州) on their way to Mexico. Many American people love to see these bright- colored black- and- orange butterflies, but they need our help to stay safe and healthy.
Every year, monarch butterflies travel south to Mexico in the fall and fly back next spring. As the monarchs go south, people in Missouri might start seeing more of these beautiful things. They' ve already been found in places like Kansas City, and even in smaller towns like St. Joseph.
Sadly, the number of monarchs has dropped by 80% in the past twenty years. Monarch caterpillars(毛毛虫) need to eat milkweed (乳草) to grow. Much of the milkweed in the country is gone because of the overuse of herbicides(除草剂) in farming. Without these plants, monarchs have no place to live or find food.
Monarchs plays an important role because, like bees, they can carry pollen(花粉), which help plants make seeds and fruit. Here are some things you can do to help these amazing butterflies:
Plant Milkweed:This is the only plant where monarchs lay their eggs. By planting milkweed in your garden, you can give these butterflies a place to stop and rest during their trip. You can also plant other flowers to provide food for the adult butterflies.
Take Photos: If you you see a monarch, take a photo and up load it to the Western Monarch Milkweed Mapper. You can help follow the movements of monarchs and understand where they are during the year, which is valuable information for researchers.
Help Fight Global Warming:Changes in the weather are making life harder for monarchs. Bad weather hurts milkweed and when the temperature is too high or too low, it's difficult for monarchs to grow up. By doing things to help the environment, like recycling and saving energy, you can help slow down global warming and protect the monarchs.
