Also, in China, where Procambarus Clarkii (red swamp) has been invasive for many decades. Genetic testing of a sample of 175 crayfish indicated the presence of 4 clones where the odds by sexual reproduction are about 1 in 10,000 (meaning that these apparent clones were likely produced by parthenogenesis)

I've had dates where the lady suddenly developed an interest in parthenogenesis. Oddly, things never seemed to go well thereafter.
