Diurnal — Having most activity during daylight. It describes when behaviors such as foraging, movement and social signaling are usually observed; it does not mean remaining in direct sun throughout the day.
Understanding by example
Even a day-active anole rests behind leaves or moves into shade. Separate simply being visible from actively moving or foraging, because an animal sitting at a resting site does not by itself indicate its activity level.
Common misconceptions
Do not treat diurnality and a need for intense heat or UVB as the same trait. Habitat, body size and access to shade differ among diurnal species. Check species-specific lighting evidence and preserve an undisturbed night period.
