蚜虫迁徙

剩下的 | | Shout (0)

上学路上到处飞舞着一种细小的昆虫,搞得满身满脸全是。下午看报说这是大豆蚜虫,目前全校、全县、甚至全东伊利诺伊的空气里都充满了此虫。它们在夏末要从大豆田迁徙到树上产卵过冬,整个迁徙过程大概要好几周。比较奇怪的是前几年都没有碰到这种情况。我找了一份比较详细的问答,但也不清楚今年突然蚜虫大增的原因。

这种蚜虫只爱大豆和一种叫buckthorn的树,十几年前从亚洲移民来米国,作风强悍,没有天敌。

…the storm is finally over, the sky wild and exhausted. We went up to the observatory and the gods were with us. They gave us the most beautiful rainbow i've ever seen. I closed my eyes and cried.
