Abstract

ABSTRACT The advantage for camouflage of variation in colour forms (binary, multi, or continuous) is a topic of increasing interest, but there are few long-term studies. We found that the ratios of colour forms of 337 polymorphic Manuka moths (Declana floccosa), recorded at one location, did not change over 42 years. This unexpected stability, in the face of probable bird predation against commoner forms and genetic drift, might result from the moth’s continuous variation that prevents predators forming a specific search image, or an unchanged food supply for the larvae. The flight period change from summer to winter, apparently the first recorded, was possibly driven by wasp (Vespula vulgaris) predation after their arrival about 1980.

Declana floccosa Walker的多形态稳定性和飞行周期的变化，1858年（鳞翅目：几何科），新西兰，1974–2016

摘要伪装颜色形式（二元、多重或连续）变化的优势是一个越来越受关注的话题，但很少有长期研究。我们发现，在一个地点记录的337种多态性麦卢卡蛾（Declana floccosa）的颜色形式的比率在42年内没有变化。面对可能的鸟类对常见形态的捕食和基因漂移，这种出乎意料的稳定性可能是由于蛾的持续变异，阻止捕食者形成特定的搜索图像，或幼虫的食物供应不变。从夏季到冬季的飞行周期变化，显然是第一次有记录，可能是由黄蜂（Vespula vulgaris）在1980年左右到达后的捕食引起的。

期刊介绍： The invertebrate diversity of New Zealand is of great interest worldwide because of its geographic isolation and geological history. The New Zealand Entomologist plays an important role in disseminating information on field-based, experimental, and theoretical research. The New Zealand Entomologist publishes original research papers, review papers and short communications. We welcome submissions in all aspects of science regarding insects and arthropods in a New Zealand or Australasian setting. The journal’s subject matter encompasses taxonomy, phylogenetics, biogeography, biological control and pest management, conservation, ecology and natural history. The journal is the official publication of the Entomological Society of New Zealand. Papers published or submitted elsewhere for publication will not be considered, but publication of an abstract or summary elsewhere (e.g. conference proceedings) does not preclude full publication in the New Zealand Entomologist. Accepted papers become copyright of the Entomological Society of New Zealand. The journal is published in English, but we also welcome publication of abstracts in Maori.
