Abstract

ABSTRACT: Small swarms of male Leseha vespa Smith & Nishida, 2019 flew during the morning hours searching for the much less abundant females on the upper surfaces of protruding leaves of various plant species at a site where a large population of the host fern Phlebodium pseudoaureum had been recently decimated (probably by L. vespa larvae). Males showed no sign of aggressive behavior toward other males, and only poor abilities to locate females resting on leaves. Although >100 male-female interactions were observed, they seldom led to copulation, as females were generally unreceptive. The males probably used visual cues to choose leaves, but the short-range cues that they used to encounter females there were not clear. Individually marked males returned to the same site for up to 11 days.

摘要/ ABSTRACT摘要:在一个寄主蕨类植物假金丝兰(Phlebodium pseudoaureum)最近遭到大量屠杀(可能是被L. vespa幼虫)的地点,一群雄性Leseha vespa Smith & Nishida 2019在早晨的几个小时里,在各种植物突出的叶子的上表面上寻找数量少得多的雌性。雄性没有表现出对其他雄性的攻击行为,只有很差的能力来定位躺在树叶上的雌性。虽然观察到100多只雄性和雌性的互动,但它们很少导致交配,因为雌性通常不接受。雄性可能使用视觉线索来选择树叶,但它们用来在那里遇到雌性的近距离线索并不清楚。单独标记的雄性会回到同一个地点长达11天。
