Butterflies in particular have very specific demands as to their environment. They will not breed unless they have adequate space in which to fly and the right amount of sunshine. The females produce only a small number of eggs, and do not lay them all in one place. They are far from being "plague" insects.
特別是蝴蝶，對環境的要求嚴格，需要一定的飛翔空間與適當的陽光才願求愛、繁殖，雌蝶又不將卵產在一處，卵數又少得可以數出來，絕非「駭客」型昆蟲。
