嘉翠蛱蝶的生物学特性初步观察

在白水江自然保护区研究了嘉翠蛱蝶Euthaliakardama (Moore)的生物学特性。嘉翠蛱蝶 1年 1代 ,以老熟幼虫在棕榈棕中越冬 ;幼虫于翌年 5月中下旬从棕榈棕中爬出 ,取食嫩棕叶并于 6月初化蛹 ,7月至 8月均可见成虫 ,8月中旬在棕榈上发现大量卵 ,9月至 1 0月为幼虫期 ,1 0月底以幼虫在棕叶中越冬。卵和小幼虫易被天敌捕食 ,存活率低。

Primary survey on bionomics of Euthalia kardama

This study deals with bionomics of Euthalia kardama. Euthalia kardama: Univoltine. Overwintering in elder larvae in the old leaves of palms in late October. The larvae emerge from the leaves in mid-to late-May of next year and feed on fresh leaves of palms. The larvae will become pupae in early June. The adults will fly from July to August, and larvae will emerge in September to October. The adults prefer to fly in sunlight very quickly and actively. Its egg is black with tumor-shaped projector. Larva is greenish with long thorns along two sides of segments. Pupa is also greenish with five bright silver-metal-shine spots on back.
