As Monarch Butterflies Journey North, Gardeners Can Help Protect Species, Researcher Says

It has been a hard winter for Monarch butterflies. The low temperatures, storms and habitat destruction have all threatened the butterflies' overwintering population in Mexico.Taylor says that a lot of different butterflies are very harmful. He says that a lot different butterflies come out when it has a cool , warm or hot temerature. There are mre harmful butterflies then there that aren't.



i think that their should be a way to find out the different species that are dangerous and that are not dangerous. We should be aware of all the different types of harmful animals. It's better for the butterflies to be going up north then messing with people's gardens.
