近日，巴基斯坦部分地区的洪水造成了一个古怪的现象，蜘蛛上树了。由于躲避洪水，蜘蛛们大规模的迁移到高出，这就造成了这一地区出现了一个“蜘蛛上树”的奇怪。如今，密密麻麻的蜘蛛网挂满了Sindh 河岸的大树。但似乎也有好处，一些人认为这些蜘蛛网至少会捕食掉沿河的蚊虫，减少疾病的传播。Trees cocooned in spiders webs, an unexpected side effect of the flooding in Sindh, Pakistan
An unexpected side-effect of the flooding in parts of Pakistan has been that millions of spiders climbed up into the trees to escape the rising flood waters.
Because of the scale of the flooding and the fact that the water has taken so long to recede, many trees have become cocooned in spiders webs. People in this part of Sindh have never seen this phenomenon before - but they also report that there are now less mosquitos than they would expect, given the amount of stagnant, standing water that is around.
One theory is that mosquitos may be getting caught in the spiders webs, which would be one blessing for the people of Sindh, facing so many other hardships after the floods.
