Hornet nest at my parents' home in Taipei City. They came to build a new nest every year for several years. My parents didn't bother them and they got along quite well with the hornets.They moved away in late autumn and came back next spring.
我爸媽家的虎頭蜂窩，在台北市。牠們之前每年都會來做窩，連續了好幾年，冬天牠們搬走了，我們就把舊的蜂窩摘下來，春天牠們又來做新巢。多年來與我們相安無事。後來牠們就沒有再回來了，不知道是為什麼.......... (不過也安心一點了啦!! 總是無法預測牠們的行為啊!)
