Cicadas (蝉) are natural part of summer, singing loudly and proudly. They are harmless to humans, but can damage (毁坏) trees. “Cicadas are harmful to cherry trees and sweet osmanthus trees,” said Ruan Wangzhou, chief of the Hangzhou Greening Management Station, which is in charge of the gardens and greenery throughout Zhejiang’s provincial capital.
Take cherry trees for example. Each July and August, the juice in their buds (花蕾) makes them the favorite food and egg-laying places for cicadas. The insects’ laying eggs in the buds can cause the trees to die.
To solve the problem, the station invited people to catch cicadas in a park in Hangzhou this August. Over 50 people showed up, far more than the expected number 20. The station also invited Jin Sucui, a 62-year-old expert from Lishui, Zhejiang, to teach people how to catch cicadas.
“Catching cicadas is actually quite simple,” Jin said. “All you need is a long stick, a piece of sticky paper and a bag to hold the cicadas. Just keep your hands steady (平稳的) and your eyes on the sticky paper.” Jin caught hundreds of cicadas within two hours.
Ruan said he hoped more people could take part in the activity. “Parents can bring their children along to catch cicadas during summer as a way to get in touch with Mother Nature and develop their awareness of protecting the environment,” Ruan added.
