Why some species of plants and animals vary more in number than others is a central issue in ecology. Now researchers have found an important finding to answer this question: Individual differences have a positive and stabilizing effect on the number of moths. Species with varying color drawing are generally more numerous and fluctuate less in number from year to year. This could help to explain why some insect species in some years are very abundant pests and cause substantial damage in agriculture and forestry.
