A diapause is a period
of physiologically enforced dormancy
between periods of activity
Hibernate and estivate are related words. Diapause differs from these because it does not specify a distinguished type or amount of time spent in suspension.
A prolonged diapause, typically lasting a few years, is a common trait among many species of insect during their larval phase.
Anagrams of diapause include: a paid use, PA USA die, and asia dupe.
