#I'm down to have some internet friends to discuss anything reptiles and invertebrates

The size difference between those two females Porcellio spinicornis I collected earlier today, with their pouch full of mancae, makes me wonder if it's a genetic mutation to be bigger or if it's just age difference? Most P. spinicornis here are the size of the female at the bottom but with our winters, most don't live more than 6 months. So the bigger one could be older? I mean, I would have my answer in a year since I started my own little colony.

Any speculation are welcome!
