Saga pedo
''Saga pedo'' is a species of bush cricket, spread throughout the European part of the Mediterranean, and Asia as far east as China. It is a wingless bush cricket, with the body size of up to , which makes it one of the largest European insects.〔 Colloquially known as the predatory bush cricket, or the Spiked Magician (due to the "enchanting" manner in which it waves its forelimbs as it approaches its prey),〔Blondel, J., Aronson, J., Bodiou, J-Y. and Boeuf, G. (2010) The Mediterranean Region. Biological Diversity in Space and Time. Third Edition. Oxford University Press, Oxford〕 it is uncommon among its kind due to its carnivorous lifestyle, most often preying on smaller insects, with a known tendency towards cannibalism 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 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 °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.
