Seasonal Life History
Overwintering as adults in pair. Oviposition during hibernation. One genaration per year. New adults appear in early summer.
Comments by Kohno
I studied the biology and population dynamics of this species when I was a student. Hatchlings of ths species eat their mother as the first diet for them. The hypothesis on the evolution of the cannibalism in this species is proposed in Kohno (1997)
