Survival Strategies
Two major strategies for winter survival have evolved in the Class Insecta due to their inability to generate significant heat metabolically. The first, migration, is a complete avoidance of the temperatures that pose a threat. If an insect cannot migrate, then it must stay and deal with the cold temperatures in one of two ways. This cold hardiness is separated into two categories, freeze avoidance and freeze tolerance.

Famous quotes containing the words survival and/or strategies:
“I do not approve the extermination of the enemy; the policy of exterminating or, as it is barbarously said, liquidating enemies, is one of the most alarming developments of modern war and peace, from the point of view of those who desire the survival of culture. One needs the enemy.”
—T.S. (Thomas Stearns)
“By intervening in the Vietnamese struggle the United States was attempting to fit its global strategies into a world of hillocks and hamlets, to reduce its majestic concerns for the containment of communism and the security of the Free World to a dimension where governments rose and fell as a result of arguments between two colonels’ wives.”
—Frances Fitzgerald (b. 1940)
