It turns out that not all Taiwan's dragonflies lay their eggs in water. The female A. petalura taiyal deposits hers on bryophytes, or occasionally among fallen leaves. When temperatures in the high mountains fall below freezing point, lakes and ponds may easily freeze. But plants remain moist and give protection against the cold, so they make the best nursery for baby dragonflies.
原來，蜻蜓並不全是點水產卵，泰雅晏蜓媽媽蜻蜓點「草」，將卵產在苔蘚上，偶而也將卵下在枯枝落葉間，由於山高地凍，湖泊容易結冰，植物保濕、防凍雙效合一，成為寶寶的最佳保護所。
