Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
In late autumn and during winter, they retreat down from the top 5 cm of soil and burrow down between 50–200 mm into the soil. During this phase, the grubs undergo a colour change from grayish/white into a yellow/cream colour. Once they reach the appropriate depth, the grub empties its stomach and starts to form a smooth oval shaped cell.
Many plants and seeds recognize this and enter a dormant period in the fall to stop growing. The grain is a popular example in this aspect, where they would die above ground during the winter, so dormancy is favorable to its seedlings but extensive domestication and crossbreeding has removed most dormancy mechanisms that their ancestors had.

Warm-season grasses, such as bermudagrass, St. Augustinegrass, and zoysiagrass, go dormant in winter. Grass blades turn brown and some become brittle. Grass blades turn brown and some become brittle.
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
Make sure plants enter the dormant season in a healthy and vigorous condition. Proper irrigation during autumn will help prepare landscape plants for the coming winter. Choosing Cold-Tolerant Plants
Once the temperature drops below the mid-40s, iguanas go into a dormant or cold-stunned state and sometimes fall out of trees where they perch. They appear to be dead, but they are not.
Growth begins at temperatures above 15 °C (59 °F) with optimum growth between 24 and 37 °C (75 and 99 °F); in winter or in the dry season, the grass becomes dormant and turns brown. Growth is promoted by full sun and retarded by full shade, e.g., close to tree trunks.
