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.
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.
