Do Bugs Sleep? Why Do We Need to Learn About Their Circadian Rhythm?

Bugs need to rest like us, so they sleep. However, their circadian rhythm differs depending on what they eat.

Do Bugs Sleep?

Bugs are insects from the Hemiptera group; their mouthparts must be piercing. Spiders are not Hemiptera; cicadas are. However, in casual speech, "bug" usually refers to something creepy-crawly. It describes land arthropods with at least six legs, like insects, spiders, and centipedes.

Bugs include true bugs, flies, cicadas, beetles, aphids, Hymenoptera, ants, dragonflies, ladybugs, ground beetles, and more.

If you are among those wondering whether bugs sleep, the answer is "Yes." Barrett Klein, a biologist at the University of Wisconsin, La Crosse, who studies the sleeping lives of honeybees, confirmed this.

Some of them are like humans. The queen fire ants get to enjoy nine hours of sleep each day. On the other hand, the workers settle for hundreds of little sleep, totaling fewer than five hours a day.

Actual bug sleep is characterized by more relaxed muscles, "drooping in the direction of gravity," and immobility. You will also observe an "increased arousal threshold." The duration required to jar the bug into alertness is another sign.

Not only is sleep deprivation dangerous for people, but it also has negative effects on insects. In lab experiments, researchers have demonstrated that insects deprived of sleep are kept awake during resting hours to compensate by obtaining more rest when sleeping.

Klein also experimented with this in 2010 to investigate sleep deprivation in honeybees. He built an insominator, a device that sounds like a supervillain.

In his trials, bees tagged with steel had trouble sleeping due to magnets in the inseminator, whereas their copper-tagged nestmates slept through the night.

Through a movement known as a "waggle dance," bees communicate with one another about possible nest sites and food sources. The study found that sleep-deprived bees "behaved quite differently than bees with the more precise directional information."

For example, the dances of the drowsy bees were not as elaborate as those of the sound-sleeping bees and, therefore, were not as helpful as those who had enough sleep.

Bugs' Sleeping Cycle

The bugs' sleeping cycle depends on when their food is most accessible; certain insects are nocturnal. For example, bed bugs are known to feed while their victims are asleep, while cutworms chew their leaves at night to evade predators. But bees sleep through the night because they pollinate during the day when the flowers they seek are open to the sun.

A stage halfway between sleep and hibernation that some insects, like moths and butterflies, go through when their metabolic and psychological activity slows down at a particular temperature is called "torpor."

Like humans, bugs have different sleep cycles that are impacted by several factors, including age and sex, sleep-inducing medicines, and caffeine. While not every bug sleeps at the same depth or on the same cycle as the typical mammal, their habit of sleeping and its necessary functions are the same.

Why Do We Need To Know About Bug's Sleeping Cycle?

Finding out more about the local animals is not only fascinating, but it can also make it easier for humans to locate and, in an emergency, eliminate bug pests. Since bugs are less receptive while tired or sleeping, having an exterminator target their nests is more efficient and effective. For instance, poisoning wasp and yellow jacket nests during the evening when they are all in their nests is more effective.
