【英语时差8,16】哥斯达黎加黄蜂的男性规则

（单词翻译）

 Behavior like this, however, is reversed in a Costa Rican wasp¹ species. The males in this species not only attack their sisters, who curl into submissive positions or flee, but they steal food from the queen herself, their very own mother. These wasps² live in a cloud forest in Costa Rica. Whereas wasp colonies in temperate³ zones can only reproduce for a brief period in the summer, these colonies can mate year round. Thus, a scientist studying these wasps proposes that it’s in the females’ interest to put up with the abuse of their brothers and to let them hang around longer because it increases the males chances of mating with queens from other nests, which makes the colony more biologically fit.
