In the past two days, many citizens have reported that there are flying feathers, and white feathers float on both sides of the road, which is simply "Flying Snow in May", is it that the willows in Hangzhou have come back? What the hell is this floating around?
In Hangzhou, there are only three kinds of trees that produce flying feathers: plane tree, female pearl willow tree and poplar tree, usually in March and April is the high incidence period of "flying feathers". Poplars are only occasionally seen around the ring road and expressway. For the suppression of plane wood flying and willow wool, Hangzhou has also been very mature. In March of this year, the plane trees were pruned with controlled fruit, and the flying feathers have been greatly reduced.
Chen Liang, deputy chief of the conservation section of the Hangzhou Landscaping Development Center, said: "In the evaluation of the suppression of willow silk last year, the efficiency of suppression is still more than 95%. ”

But today
The reporter saw it at the Chaowang Branch Road in the Ninth District of Zhaohui
The white flocculents stick to the tree
There are white flowers on the ground
Walk up
There is also a sticky feeling
What's going on here?

After the on-site inspection of the experts of the Municipal Landscaping Development Center, the white hairs of the willow are misunderstood, and these white hairs are the white waxy secretions left by the green paulownia wood lice.
Chen Liang, deputy chief of the conservation department of Hangzhou Landscaping Development Center, said: "This green paulownia lice features that it will produce a large amount of white flocculent wax secretions when it harms the green trees, and this secretion will also drift down with the wind. This worm is not harmful to people, and its waxy secretions will not have any allergies even if they are contaminated on the skin. ”
