摘　　要：利用扫描电镜观察了端黑萤(Luciola praeusta Kiesenwetter)成虫及幼虫头部的形态,结果表明:端黑萤成虫复眼发达,但口器退化,仅由上唇、1对上颚、1对下颚须及下唇组成;幼虫有1对不发达的侧单眼,1对发达的、左右对称的3节触角,其口器非常发达,具有1对锋利的、中空的镰刀状上颚,1对下颚须,1对下唇须和1对内颚叶。端黑萤幼虫口器的典型特征为上颚近1/2处向内侧弯曲成1个齿状突起。The external morphology of the larval and adult head of firefly,Luciola praeusta Kiesenwetter（Coleoptera： Lampyridae） was observed by scanning electron microscope. In adult,the mouthpart was not well developed whereas the compound eyes were extremely developed. The adult mouthparts were comprised of labrum and then paired mandibles, paired maxillae and single labium. The larvae had well-developed three segments of antenna and a pair of lateral oceltus. The mouthpart of the larval was well-developed, composed of one pair of sharp, hollow and curved mandibles, max palp, lacinia and labial palp. The larval mandibles had one distinct character, namely, a teeth structure on 1/2 inner side of its mandible.
