Abstract

The larval morphology, life cycle, and nutritional values of Lepidostoma abruptum Banks 1931 are described and discussed. The larval case is rectangular in cross section, made of rectangular pieces of leaf. The larva of L. abruptum shares the morphological characteristics of other Lepidostoma spp. which have been described from different countries and continents. The head capsule widths of 74 specimens were measured and plotted to determine the instars of the larvae. This species is non-seasonal. In addition, the moisture (68.87%) and dry-weight nutritional values of the specimens were determined: protein (49.08%), total fat (27.13%), total dietary fiber (5.9%), omega-3 (0.15%), omega-6 (6.04%), and omega-9 (11.7%). Larvae of this species live in small debris pools dominated with leaf litter and small branches.

摘要

描述并讨论了1931年班克斯氏短突鳞石蛾（Lepidostoma abruptum Banks）的幼虫形态、生命周期和营养价值。幼虫的外壳横截面呈矩形，由矩形叶片组成。短突鳞石蛾幼虫具有其他已在不同国家和大陆描述过的鳞石蛾属物种的形态特征。测量并绘制了74个标本的头壳宽度，以确定幼虫的龄期。该物种无季节性。此外，还测定了标本的水分（68.87%）和干重营养价值：蛋白质（49.08%）、总脂肪（27.13%）、总膳食纤维（5.9%）、欧米伽-3（0.15%）、欧米伽-6（6.04%）和欧米伽-9（11.7%）。该物种的幼虫生活在以落叶和小树枝为主的小碎片池中。
