Woodlice are more active as they move from a dry area to humid area. The innate behavior that is being displayed here is migration. Migration is the transfer of one group of organism from the original habitat to a different place or habitat. It is a universal move for almost all of the organisms in the ecosystem. Migration is done as a form of adapting into an imperfect habitat or environment. Animals also migrate in a quest to look for better places to breed and and reproduce.
