Scarabaeus Cicatricosus

scarabaeus cicatricosus

Scarabaeus cicatricosus is a remarkable species of dung beetle native to the western Mediterranean, particularly the southern Iberian Peninsula and parts of North Africa. As a quintessential ecosystem engineer, this industrious insect plays an indispensable role in nutrient cycling, soil aeration, and seed dispersal. By sculpting and rolling massive spheres of mammalian dung, it secures both a rich food source for itself and a nursery for its future offspring. Watching this beetle navigate rough terrain while pushing a ball several times its own weight is a testament to its extraordinary strength and biological determination. Sadly, changes in traditional pastoral farming and the widespread use of livestock pharmaceuticals pose significant challenges to its survival, making this species a vital focus for regional conservation efforts.

生息地: Found in dry Mediterranean grasslands, pastures, and open shrublands where herbivorous livestock graze.

外見

This medium-sized beetle typically ranges from 2.0 to 3.0 centimeters in length and is characterized by a robust, oval body with a deep, matte-black coloration. Its most defining feature is the textured, heavily punctured surface of its elytra, which resembles a series of scars or cicatrices—giving the species its scientific name. It possesses broad, spade-like forelegs heavily modified for digging and sculpting dung, while its fan-like antennae are highly sensitive to chemical cues in the air.

おもしろい事実

Like other Scarabaeus species, they roll dung balls backward using their hind legs while walking upside down with their heads facing the ground.

The species name 'cicatricosus' refers to the scar-like craters on its wing covers, which help distinguish it from other smooth-bodied scarabs.

They are highly sensitive to the chemical components of fresh dung, capable of flying directly toward a new dung source within minutes of its deposition.

特殊能力

This beetle uses the polarized light of the sun, moon, and even the Milky Way to maintain a straight course while rolling dung balls away from competitors.

Equipped with specialized, serrated forelegs and a shovel-like clypeus, it can rapidly burrow into compacted soil to bury its dung ball safely.

It is capable of rolling and transporting dung spheres that weigh up to several dozen times its own body mass over uneven terrain.

食性と食事

Feeds almost exclusively on the dung of herbivorous and omnivorous mammals, favoring fresh cattle, sheep, and horse droppings.

年齢による違い: Larvae feed inside the buried brood ball on the dung provided by their parents, while adults actively forage for fresh dung on the surface.
