Life Cycle
The female attains sexual maturity three to four weeks after hatching and starts laying eggs. A single egg is deposited by stabbing the long, sharp ovipositor into the soil at a suitable site. The female will lay from twenty five to eighty eggs. Development depends largely on the ambient temperature. At 20°C or more, the eggs start to develop immediately, the nymphs hatching after approximately 40 to 85 days (again depending on the temperature). At colder conditions, the eggs enter diapause, which is a delay in development and can result in the eggs remaining buried for up to five years (mostly two to three). After hatching, which occurs around May, the nymphs go through six or seven instars before attaining sexual maturity, and live for four to six months after that.
Saga pedo is also uncommon in that it mostly reproduces asexually, with parthenogenesis. The population therefore appears to consist solely of females and there is no reliable record of a male of this species. They also have the largest number of chromosomes among members of the genus Saga - 68 - and are probably tetraploid.

Famous quotes containing the words life and/or cycle:
“We have had many harbingers and forerunners; but of a purely spiritual life, history has afforded no example. I mean we have yet no man who has leaned entirely on his character, and eaten angels’ food; who, trusting to his sentiments, found life made of miracles; who, working for universal aims, found himself fed, he knew not how; clothed, sheltered, and weaponed, he knew not how, and yet it was done by his own hands.”
—Ralph Waldo Emerson (1803–1882)
“Only mediocrities progress. An artist revolves in a cycle of masterpieces, the first of which is no less perfect than the last.”
—Oscar Wilde (1854–1900)
