Where is the butterfly s home?

Michael Raupp is a professor of entomology at the University of Maryland.

On a rainy day, butterflies do nothing more than shelter from the rain. For a monarch butterfly weighing only 500 milligrams, a storm is no small feat: it is hit by a 70-milligram drop of rain, which may be the weight of two small bowling balls.

Heavy rains can also hinder the movement of butterflies. In order to prepare for flight, these aerobatic pilots have to let the sun shine directly on their wings, because only then can their flight muscles (wing muscles) be quickly warmed, and cloudy days block out the solar radiation necessary for their takeoff.

As a result, when the clouds are thick and the sky is dark, butterflies look for shelter from the rain in their habitats: places to shelter from the elements, such as tall pole grass or leafy plants. When the sun smiles again, they often return to the blue sky within a few minutes, looking for fun.

You don't have to worry if the butterfly does get caught in the rain, because the butterfly's wings are made up of hundreds of tiny scales, similar to the scales on a fish. It also shelters the rain when it rains, so that they don't get really wet.

Answer: Butterflies do not have a fixed home, when it rains, butterflies will choose flowers and leaves nearby and put their wings close to the back of the leaves, that is, to prevent rain and wind; There are also butterflies that often choose some places with relatively dense density, such as grass and wheat fields, because their leaves are relatively dense and have the effect of keeping out the cold; There are also places where tall poles or leafy plants can shelter from the wind and rain; They will also hide in mushrooms, eaves, and other places where they can block the rain. Also, don't worry about butterflies getting wet when it rains, because butterfly wings are made up of hundreds of tiny scales, similar to the scales on fish, and can also block the rain when it rains, so that they don't get really wet. In addition, butterflies and dragonflies can predict the weather just like dragonflies and swallows, and will find a place to hide in advance.
