这句话是说当locusts与其他的同类在一起时才变得兴奋。。。

如果换成E，就没有这意思了。

此外，貌似只有if和then才能连接。

啊。。我突然觉得是不是因为如果是E的话，后面的they就变成指代others of their species了？？

我觉得就算不指代other of their species， they去指代locusts，那也不对。
placed with是分词做状语，修饰主语they，变成placed with others of their species的they become，没有当……时的意思了。

还是咖啡印象说得对，应该考虑A的逻辑语义，代词指代次要考虑。
