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.
