The answer is yes; caterpillars do sleep. They spend most of their time looking for food. Caterpillars lie still during the food stage and take shelter in bushes, trees, and other protected places.
“Caterpillars can’t sleep in the same way that mammals sleep. For one thing, they don’t have eyelids,” says Christina Agapakis, editor of the blog Small Things Considered and a postdoctoral researcher at UCLA. “Instead, caterpillars go through periods of quiescence, which is just a fancy word for lying still.
Quiescent caterpillars are likely to be found in bushes, trees, or other protected places. They can also enter a deep sleep state called torpor when temperatures drop or if they’re too cold to digest food properly.
Do caterpillars sleep at night?
Yes, they do.As caterpillars grow larger and older, they go into periods of inactivity. These periods are known as instars. Instars are molting stages, and each one is a little longer than the last.
Caterpillars go into instars to grow bigger, shed their old skin, and then eat it to get back some of the nutrients they lost. Molting takes time, so it is normal for caterpillars to go inactive, regardless if it’s daytime or nighttime, and then eat their molted skin afterward.
Where do caterpillars sleep at night?
Caterpillars can also be found in different places to sleep. Some sleep on the underside of leaves, some sleep in the soil, and others will make their own little shelter from silk or other materials.
Caterpillars are mainly active during the day, but they do sleep at night. As a matter of fact, they spend most of their time sleeping. A lot of caterpillars have a protective covering over them when they sleep because there are predators that would like to eat them.

Do caterpillars sleep in cocoons?
No, caterpillars do not sleep inside cocoons. As we have seen, the caterpillar does not turn into a butterfly in the cocoon, but rather, it is merely a resting stage for the new creature to come out. During this time, rather than a dead rest, there is actually a lot of activity inside the cocoon. All throughout the cocoon and the chrysalis, the caterpillar is transforming into a new creature.
Do caterpillars sleep upside down?
Yes, caterpillars do sleep. And yes, they sleep upside down, but not all the time. They are typically found hanging upside down because most species of the caterpillar have more than one set of prolegs near the rear of their bodies. These extra legs (or prolegs) and the usual six true legs found at the front of the body help the caterpillar grip objects when it climbs.
Do caterpillars sleep in soil?
Yes, caterpillars do sleep in the soil. The young ones often crawl down into the soil to pupate, and other solitary species will rest in the soil during the day. Social species such as ants, bees, and wasps often construct a special chamber for the larvae to rest in, but this is not really a “nest,” as we would understand it.
Do monarch caterpillars sleep?
Monarch caterpillars can be active during the day, but they typically rest when it is cool at night. Caterpillars do not sleep in the same way as humans. They don’t actually close their eyes and enter into a deep slumber. Instead, they take short naps throughout the day and night. These naps are called catnaps because they are very short, lasting only a few minutes to an hour.
Monarch caterpillars can also rest for long periods of time during the day when it is hot outside or when they are hiding from predators under leaves. When they do this, they look like they are sleeping because they appear still and may even open their eyes and close them again, but they often remain alert to changes in their environment.
Caterpillars actually do sleep, but only for a while. It is a form of energy conservation for when it is most needed. Thousands of caterpillars awaken from their slumber every day and begin searching for food and devouring plant leaves.
