This is a case for suspended judgement and a need for more observation. Reproductive Behavior: Life History. No clear-cut data are available as to the period of gestation. Female scorpions of C. sculpturatus isolated for over 6 months have produced young. Matthiesen (1960), after reporting on a supposed act of insemination, states "The female . . seemed to be pregnant. She was separated directly after copula- tion, and, after 12 or 13 days gave birth to more than 20 offspring. A second birth occurred 115 days after the first!' Reports for the gestation period vary and the observations seem to have been made on females that were not isolated for a period of 6 months or more before mating occurred and a previous insemination could have taken place. Scorpions are ovoviparous. The young break out of the egg membrane and crawl upon the female's back (Fig. 4). The route is. Figure 4. C. sculpturatus with first instar young pickaback. Note the plumpness of the (yolk filled) pre-abdomens. Development is incomplete. usually over the cheliceral area. If accidentally one of the young is caught in the chelicera the female may eat it and, subsequently, a large number of the litter. The size of the litter may vary from 12 to.
