However, the border between outbreaking and non-outbreaking populations of geometrid moths is likely to move northward if climate changes.    From Wordnik.com.  [Effects of changes in climate and UV radiation levels on structure of arctic ecosystems in the short and long term] Reference

Over 30 geometrid moths of the genus Chrysolarentia are found only in alpine areas, demonstrating rapid speciation over a small geographical area.    From Wordnik.com.  [Tasmanian Central Highland forests] Reference

Looper: applied to geometrid and other caterpillars in which some or all the middle abdominal legs are wanting and which move by bringing tail to thorax and forming a loop of the intervening segments.    From Wordnik.com.  [Explanation of Terms Used in Entomology] Reference

The natural cyclic fluctuation of geometrid moth numbers is driven by density-dependent factors that lag outbreaks in time, including buildup of natural enemies, disease, and reduced food quality, and by weather conditions at all life stages.    From Wordnik.com.  [Climate change and insects as a forest disturbance in the Arctic] Reference

The projected increase in the frequency of winter warming is very likely to severely suppress population densities; distort the cyclic dynamics and degree of geographic synchrony in lemmings, voles, and geometrid moths; and in some cases even lead to population extinctions.    From Wordnik.com.  [Phenotypic responses of arctic species to changes in climate and ultraviolet-B radiation] Reference

Warmer summer temperatures with no change in winter temperatures are likely to reduce the geometrid moth outbreak potential, because higher densities of moth predators associated with warm summers would partially protect birch, while the winter limitation on the moths would still operate.    From Wordnik.com.  [Climate change and insects as a forest disturbance in the Arctic] Reference

Parenthetically, peppered moths are geometrid moths – it appears peppered moths do not show active seeking of matching backgrounds, unlike Sargent’s underwings and your little beige guy there.    From Wordnik.com.  [Anniversary Moth - The Panda's Thumb] Reference
