Yes, scarab beetles can and do fly, though their flight is often described as heavy and clumsy compared to other insects. The term “scarab” covers a large family (Scarabaeidae) that includes dung beetles, June beetles, and flower chafers, and while they all have functional wings, their flight behavior varies widely by species and environment.
What Counts as a Scarab Beetle?
The family Scarabaeidae is one of the largest beetle families, with over 30,000 species worldwide. In everyday language, “scarab” usually refers to the dung beetles of the subfamily Scarabaeinae, especially the sacred scarab Scarabaeus sacer of ancient Egypt. But the family also includes:
- June beetles (subfamily Melolonthinae) – nocturnal, attracted to lights, and strong fliers.
- Flower chafers (subfamily Cetoniinae) – often fly during the day and are among the most agile scarabs.
- Dung beetles (subfamily Scarabaeinae) – many fly to locate fresh dung, but some, like certain Scarabaeus species, are more inclined to walk.
All scarabs have two pairs of wings: a hardened outer pair called elytra (which are not used for flying) and a membranous inner pair that does the actual work. In flight, the elytra are usually spread slightly to allow the inner wings to move, though some species, like flower chafers, can fly with their elytra closed by using a notch on the side.
How Scarab Flight Works
Like all beetles, scarabs use indirect flight muscles. The muscles attach to the exoskeleton rather than directly to the wings, so a contraction of the thorax causes the wings to beat up and down. This system is efficient but not particularly agile. Scarabs typically have a high wing-beat frequency and a relatively slow forward speed, which makes them look bumbling.
Flight is energetically expensive for a heavy beetle. A large dung beetle can weigh several grams, and to get airborne it must generate enough lift by beating its wings rapidly. Once aloft, it relies on warm air and steady flight paths rather than quick maneuvers. Many species are crepuscular or nocturnal, flying at dusk or night to avoid predators and desiccation.
Some scarabs are exceptional fliers. The green June beetle (Cotinis nitida) is known for its loud buzzing and agile, erratic flight during the day. In contrast, the sacred scarab Scarabaeus sacer is a poor flier and rarely takes to the air; it prefers to walk, pushing its dung ball with its hind legs. This difference is due to body shape and habitat – desert species that need to travel far for dung may fly more, while those in resource-rich areas can walk.
Why Do Scarabs Fly?
Flight serves several essential purposes for scarabs:
- Finding food: Dung beetles fly to locate fresh animal droppings, which they use for feeding and breeding. Some can detect dung by smell from over a kilometer away.
- Mating: Many species fly to find mates, especially at dusk when they swarm around trees or lights.
- Dispersal: After emerging from pupae, young adults fly to new territories, avoiding competition with their parents.
- Escaping danger: Flight is a last-resort defense, though many scarabs prefer to play dead or release a foul odor.
Not all scarabs fly equally. Some desert species have reduced wings or fused elytra, making flight impossible. For example, certain Eleodes beetles (darkling beetles, not scarabs) cannot fly, but among true scarabs, flightlessness is rare and usually associated with isolated habitats like islands.
Scarab Flight in Ancient Egypt
The ancient Egyptians observed the sacred scarab rolling dung balls and associated it with the sun god Khepri, who rolled the sun across the sky. They also noticed the beetle emerging from the ground, seemingly spontaneously, which they linked to creation and rebirth. However, they did not emphasize flight in their symbolism. The scarab amulets and hieroglyphs typically show the beetle with wings spread, but that is a symbolic representation of the sky and protection, not a literal depiction of flight.
In Egyptian art, the winged scarab often appears on the chest of mummies, with outstretched wings representing the heavens. This iconography is about divine power and resurrection, not about the insect’s actual flying ability. The connection between the beetle and flight was more metaphorical than biological.
Common Misconceptions About Scarab Flight
One widespread myth is that scarabs cannot fly at all because they are too heavy or because their elytra are fused. This is false for the vast majority of species. The elytra are not fused in flying scarabs; they open to varying degrees. Another misconception is that all scarabs roll dung balls. In reality, only a subset of dung beetles (the “rollers”) do that. Others are tunnelers (they bury dung underground) or dwellers (they live inside the dung). All three groups can fly, but rollers tend to fly less because they invest more energy in walking with their ball.
People also confuse scarabs with cockroaches or other beetles. A flying scarab at night near a light might be mistaken for a cockroach, but scarabs have clubbed antennae and a distinct body shape. The sound of a large scarab in flight is a low buzz, quite different from the whine of a mosquito or the silent flutter of a moth.
How to Observe Scarabs in Flight
If you want to see scarabs flying, the best time is during their active season (usually late spring to early summer in temperate regions). Look for:
- Dusk flights near meadows or pastures where livestock graze – dung beetles will be heading to fresh pats.
- Flower chafers on sunny days, visiting blossoms for nectar and pollen.
- June beetles buzzing around porch lights on warm nights.
To attract them, you can leave a porch light on or set up a white sheet with a UV light. Observing flight patterns can be tricky because they are fast and erratic, but with patience you can see them take off and land. Remember not to handle them roughly; they have strong legs with spines that can pinch.
Safety and Handling
Scarab beetles are harmless to humans. They do not bite, sting, or transmit diseases. Some species, like the dung beetles, may carry bacteria from feces, so it is wise to wash your hands after handling them. If a beetle lands on you, gently brush it off rather than swatting, as it may release a defensive fluid that can stain or irritate skin. In rare cases, large species can pinch with their mandibles if provoked, but this is not dangerous.
If you find a scarab indoors, you can catch it with a jar and release it outside. They are beneficial insects, aiding in nutrient recycling and soil aeration. No special precautions are needed beyond basic hygiene.
Frequently Asked Questions
Do scarab beetles bite?
No, scarab beetles do not bite humans. Their mouthparts are adapted for chewing plant material or soft dung, not for biting skin. Some large species might give a harmless pinch with their legs if handled, but they are not aggressive.
Why do scarabs fly into lights?
Like many nocturnal insects, scarabs are attracted to artificial lights. They use the moon for orientation, and a bright light confuses their navigation, causing them to circle it. This is a common behavior for June beetles and other night-flying scarabs.
Are scarabs the same as June bugs?
June bugs (or June beetles) are a type of scarab beetle in the subfamily Melolonthinae. So yes, they are scarabs, but not all scarabs are June bugs. The term “scarab” is broader and includes dung beetles, flower chafers, and many others.
Can a scarab beetle fly with its shell closed?
Most scarabs must open their elytra to fly, but some flower chafers (Cetoniinae) have a special notch in their elytra that allows them to fly with them closed. This gives them a more streamlined shape and greater agility in the air.
Why do dung beetles roll balls instead of flying?
Rolling a dung ball is a reproductive strategy. A male rolls a ball to attract a female, and after mating, the female lays eggs in the ball. Rolling is more energy-efficient than flying for transporting a large ball, and it also keeps the ball away from competitors. They do fly to find the dung in the first place, but once they have a ball, they walk.
Are scarab beetles endangered?
Most scarab species are not endangered, but some island endemics and those with specialized habitats are threatened. The IUCN Red List includes a few scarab species, but the majority are abundant. Habitat loss and pesticide use can affect local populations, but the family as a whole is diverse and widespread.
