The sleep patterns of caterpillars are intriguing, especially when considering the transformation they undergo to become butterflies. While it is unclear if monarch caterpillars sleep during the day, they do have periods of activity and rest. They eat large amounts in the morning and afternoon, and take naps during the hottest parts of the day. These naps, or periods of dormancy, may be their way of resting and conserving energy. Additionally, they seek shade during very hot weather, which could be a form of resting or sleeping. It is worth noting that monarch caterpillars have poor eyesight and may not distinguish between day and night.

What You'll Learn
Monarch caterpillars have poor eyesight and may not be able to distinguish between day and night
It is unclear whether or not caterpillars sleep during the day. However, one source mentions that monarch caterpillars have poor eyesight and may not be able to distinguish between day and night. This could mean that they are active during both day and night, or that they are simply inactive during the day and become more active at night.
Monarch caterpillars have a slower internal clock than humans, so they take their time with tasks. They have periods of activity where they eat large holes in milkweed leaves, followed by periods of rest. They also go through more prolonged periods of rest, during which they shed their skin.
Monarch caterpillars are known for their unique behaviour. For example, they always head for the underside of the leaf they are eating, likely for protection from predators and the sun. They also spin a strand of silk that they can hang from, which serves as a safety line if they fall off the milkweed plant.
Monarch caterpillars have two sets of antennae, with the pair at the front being larger than the pair at the back. They have three pairs of "true legs" and four pairs of "prolegs" or false legs. These legs help them sense their environment, as they can wave their front end slowly to explore their surroundings.
Overall, while it is unclear if monarch caterpillars sleep during the day, their poor eyesight may contribute to their activity patterns. They exhibit interesting behaviours and have distinct physical features that help them navigate their world.

They take naps during the hottest parts of the day
While it is unclear whether monarch caterpillars sleep during the day, they do take naps or go dormant during the hottest parts of the day. This is likely a strategy to avoid extreme heat, as butterflies of many species need to do this. Monarchs are known to retreat to shady places when it is very hot.
Monarch caterpillars have periods of activity and rest. They eat large amounts in the morning and afternoon/evening, and take naps during the hottest parts of the day. They are also known to have periods of prolonged rest, after which they shed their old caterpillar skin.
Monarch caterpillars are very slow, so observing their behaviour can be challenging. They have a flexible front end that they use to sense their environment, and they can do U-turns on narrow twigs. If disturbed, they stop moving, except for small vibrations of their antennae. After a few minutes of quiet, they resume moving or eating.
Monarch caterpillars also have a safety mechanism to prevent them from falling off the milkweed they live on. They spin a strand of silk that they can hang from, attaching it to the leaf they are on. This acts as a safety line.

They are inactive during the day and rest at night
Monarch caterpillars have a unique internal clock that runs more slowly than that of other creatures. They have periods of activity, eating large amounts in the morning and afternoon, followed by periods of rest. They also go into a more prolonged state of rest during the hottest part of the day.
Monarch caterpillars are inactive during the day, hiding from predators and protecting themselves from the sun. They tend to rest on the underside of leaves, spinning a strand of silk to hang from if they find themselves in danger of falling. They also rest at night, remaining still on vegetation like bushes and trees.
Monarch caterpillars have poor eyesight and likely cannot distinguish between day and night. They do not have eyelids, so they rest with their eyes open. They are also unable to fly if it is below 55 degrees Fahrenheit.
Overall, monarch caterpillars exhibit a crepuscular behaviour pattern, being most active at dawn and dusk, and resting during the day and night.

They eat a lot in the morning and afternoon/evening
While it is unclear whether or not monarch caterpillars sleep during the day, they do take naps (go dormant) in the hottest part of the day. They eat a lot in the morning and afternoon/evening. They have a lot of energy to store for their long trips as butterflies, so they need to eat a lot as caterpillars. They feed exclusively on milkweed, which is known as the "'host plant' for monarchs". They also eat the leaves of this plant, hiding on the underside to protect themselves from predators and the sun.
Monarch caterpillars have periods of activity and rest. They can be very active eaters, with one caterpillar, George, eating an entire milkweed leaf every half day. They also have periods of prolonged rest, during which they shed or molt their caterpillar skin to allow for growth.
Monarch caterpillars are very protective of their food source. If a caterpillar falls off the milkweed plant, it has to climb back, which is a long and perilous journey. They are smart enough not to saw off the leaf they are sitting on. They always align themselves with their rear end towards the plant's main stem, with their rows of feet clinging to the central vein of the leaf.
Monarch caterpillars are also very responsive to their environment. If you disturb them by touching them, coming too close, or shining a bright light on them, they will stop moving, except for little vibrations of their antennae. After a few minutes of quiet, they will resume moving or eating.

They are not nocturnal
It is clear that monarch caterpillars are not nocturnal. They are active during the day and rest during the night. This is called "diurnal".
Monarch caterpillars have periods of activity and rest. During their active periods, they eat large amounts of food. They also have periods of prolonged rest, after which they shed their old caterpillar skin. This process happens five times to allow for growth.
Monarch caterpillars are known to be slow and lethargic, with a clock that runs more slowly than other creatures. They are also very sensitive to their environment. If disturbed by touch, proximity, or bright light, they will stop moving, except for small vibrations of their antennae. After a few minutes of quiet, they will resume their activity or eating.
Monarch caterpillars are also very particular about their sleeping arrangements. They need to find a safe spot to hang upside down, as their survival depends on getting this right. They have short, stumpy legs and poor eyesight, so finding the perfect spot can be challenging.
Overall, while monarch caterpillars may rest during the day, their behaviour and patterns indicate that they are not nocturnal creatures.
