Alex在外边的水桶里发现的，别人告诉我们不要压死蟑螂，否则会留下更多蟑螂卵。因此我们想淹死它，但发现它竟然会飞！
We'd been told not to squash them as you get lots more from the eggs they leave so tried drowning it only to discover they FLY!
比如，我们观察过进食这些蝽卵的蟑螂，还有蜘蛛蟾蜍之类，有些鸟也吃。
We have observed things like praying mantis just feasting on them, some spiders, toads. Some birds do eat them.
