These structures allow us to know what environmental conditions animals prefer when looking for suitable habitats. Woodlice respond to dark and damp conditions. It can therefore be deduced that woodlice (as crustaceans) need to keep close to water sources in order to survive. Since woodlice are highly attracted to solid objects, and thus, to each other. Because woodlice have very simple eyesight, Nora thought that maybe they use dark and light colors to decide where to go. Another reflex behaviour is a kinesis and this is when the speed of movement or They can search for survival-related opportunities (e.g., approaching food sources or avoiding sunny areas).
