Most butterflies do not sleep in the same way that humans do.
They do not have a dedicated sleep time, but rather rest and conserve energy during periods of inactivity.
During the night, butterflies will often rest with their wings folded together and their bodies held vertically to minimize the surface area exposed to the cooler air.
They may choose to rest on a leaf, stem, or other surface, and they may also move to a protected area to sleep, such as under a leaf or in a crevice.
Some species of butterflies are more active at night and may not rest at all during this time.
