Bees and butterflies are active during the daytime. They get a lot of attention for their roles as pollinators(传粉者).But moths(蛾)aren't given the prominence they deserve.
Actually, moths are seen much less often, because they're active at night. Moth bodies often seem furry. Pollen—a yellow powder in the center of most flowers, from one flower sticks to their bodies and falls off when they move to other flowers. Scientists studied insects around nine ponds on farmlands in the United Kingdom. They visited these ponds once a month from March to October.
They studied three groups of insects: moths, bees that normally work together, like honey bees, and flying insects which work alone, such as butterflies. At the ponds, the scientists caught these flying insects and died to collect pollen from their bodies. In all, the scientists checked 838 moths, 632 other insects which work alone, and 1,548 honey bees.
By studying the pollen they collected, the scientists were able to see which plants the insects had visited. The moths had pollen from 47 different kinds of plants, including seven plants that bees don't normally visit. The honey bees had pollen from 46 different kinds of plants. The other insects that work alone had visited 45 different kinds of plants. Richard Walton, who led the study, says that bees usually choose the plants with the most nectar(花蜜)and most pollen. However, moths pollinate many different plants, filling in the gaps left by the daytime pollinators.
Not only do moths pollinate plants, they also provide important food for birds and bats.
But, like many other insects, moth numbers have dropped greatly in the last 50 years, mainly because of pesticides and the loss of natural lands. Just like bees and butterflies, moths are worth protecting. "Moths are by no means less important," says Dr. Walton.

The powwow was just fantastic! I could never have imagined how colorful and impressive this morning would be. The dances find the clothes, which were decorated with eagle feathers, attracted me.
I had heard about the powwow dancing in our culture class at Rice University, so I wanted very much to see what the Native Americans would look like in their traditional clothes.
The opening dance was scheduled to start at 7：30 a. m. Since I didn't want to miss any dances, I arrived there on time；however, the dancing began an hour late. How could I have forgotten that Native Americans have a different feeling for time, which I had learned in our class? I had intended to go back for my term survey paper as soon as the great one-and-a-half hour event was over!
First, they started to play music with their drums； it was accompanied by their low voices. “Hamma hamma…”. The music was exactly the same as I had heard in the movies.
Then, the Native Americans gradually changed their clothes； they wore their own extremely amazing clothes for the dances, with their hairstyles special and faces multicolored(多颜色的).
Finally, the competitions were started； the participants danced in different groups. They swung their arms and moved their feet in special steps, always to the beat of the music.
After one hour and a half of enthusiastically enjoying them, I took a walk along the food stands to eat some special Native American fried bread and other snacks. And I left that wonderful place for my hotel, having stayed two hours longer than I had first planned to stay.
I will never forget this wonderful morning that gave me a little view into the culture of Native Americans.
