Insects have seasonal responses to environmental deterioration or change. One basic aspect of any species ecological adaptation is its phenology.
In tropical regions where there is alternating seasonal climate, organisms are confronted with change in their ecological environment. Many insects will migrate to escape the changes but some insects like the satyrine butterflies show phenotypic and have different forms for the different seasonal climates.
Few insect species encounter environmental conditions which remain favourable for continuous growth, development, and reproduction throughout the year. Such species are said to be homodynamic. Most species however, inhabit regions in which seasonal variations in environmental conditions impose a corresponding seasonal change in rate of development. Insects have strategies to help them survive in these unfavourable conditions.
