as well. For this purpose, it has strong fore and mid legs, equipped with sharp spines. When these animals are hunting, they move about, catching their prey by suddenly leaping on them and grabbing them with their legs. Their prey is usually killed by biting into the throat, and eating is done at capture. ''Saga pedo'' is active at dusk and during nighttime, with activity slowly expanding through the day at the end of the season.

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

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 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

at a global scale. ''Saga pedo'' was reported as an accidental introduction from Europe into Tompkins Township, Jackson County, Michigan (USA) in 1970. In all, only six specimens were found from 1970 to 1972, during August and September. None have been found since by a reliable authority, so they are considered extirpated from North America. There have been occasional unconfirmed sightings in subsequent decades, and catching of several specimens in Michigan from 2004 on were reported by a local high school teacher in the New York Biology Teachers Association's publication, however, this remains to be confirmed by a scholarly source.
