What temperature condition do woodlice generally prefer when selecting resting spots?

Cool environments, often pressed against concrete or stone

While moisture is the dominant factor influencing woodlouse location, temperature plays a significant secondary role. They exhibit a strong preference for cool environments. This preference explains why they are frequently observed pressed tightly against surfaces that retain coolness, such as stone or concrete, especially when these surfaces are shielded from direct solar radiation. During the heat of summer, this tendency drives them deeper into refuges, sometimes involving slight soil burrowing beneath logs, to remain in contact with cooler substrate layers rather than sitting exposed on warmer surfaces.
