Rhinoceros Beetle


Copris hispanus -Rhinosceros Dung Beetles in a large pile of cow dung

The first Rhinosceros beetles I encountered, several years ago now, were happily working away in a big pile of cow dung deposited on a path we were walking in the Sierra de las Nieves mountains, near Ronda. My friends were not as fascinated by them as I was and hurried me along, thus depriving me of more photographs!

Copris hispanus- Rhinoceros dung beetle

Scientific name: Copris hispanus  Family: Scarabaeidae

Distribution: Found throughout the Mediterranean region.In Spain the stronghold of these fascinating beetles is here in the south of the country where cows and sometimes horses, wander freely in the woodlands and where there are still a good number of small farms with livestock reared in more traditional ways. They are less abundant in the north of the country where farming methods are more intensive.

One summer night a beetle flew in through a bathroom window and spent the night in a bath, unable to climb out

I have had more sightings of the big, black horned beetles whilst out and about in the region and around (and in) my home and garden in Sotogrande. We have no cows or horses  in the immediate vicinity, so no local dung – unless they can improvise with dog pooh, of which there is probably plenty. The nearest large animals are perhaps 1-2 kilometres away. There are old oak stands though, so I assume the conditions required for breeding are in place and there are lights that attract them at night.

There is marked dimorphism of the sexes of this species. The male has a recurved ‘horn’ on his head and on the scutum, a hollow topped by a high comb whilst the female has only a triangular plate.

Scientific name: Oryctes nasicornis (Linnaeus 1758)

Family: Scarabaeidae

Body length : 25-40mm

DistributionAlmost all of Europe, North Africa, Asia Minor, Middle East.

Habitat: These large and impressive beetles were originally inhabitants of old oak stands, but they are gradually finding their way into the neighbourhood of man’s habitations and the larvae may now be discovered in compost heaps and the like. In the natural habitat of the forest, larval development takes place in old tree stumps and takes from two to three years. Fully grown larvae measure up to 120mm and pupate in a large oval chamber.

The bulky beetles have large wings folded under the elytra (wing covers) and can fly strongly. They stay hidden during the day, but are on the wing at dusk in the spring and summer and are attracted to lights; they are generally noticed when they come to house lights.

  2. Thank you for your comment and for finding the blog. The rhino beetles are great aren’t they? We used to find them in the bath sometimes if we left a window open at night. Easier to pick up than spiders!

    • A female fell in the pool tonight. (Moraira) Scared me shitless 🙂 felt compelled to help her out though. Had never seen one before and now i know what it was thanks to you.

      • Thanks for sharing the moment Michael! I’m happy to hear you helped the poor thing out of your pool; there’s many a beetle that meets its demise that way.

  3. Hi Theresa,
    My dogs were curious about something, then went racing off down the garden, Then I heard a noise from a honeysuckle bush near to where I sat, so I went to look. Eventually got quite a fright as something clattered near my feet. Before my dogs came back and caused trouble I scooped it up into a small (empty) candyfloss bucket. Much studying and image search took place – I thought the horn resembled a rhino’s, having seen many when I lived in Africa, but simply googled ‘horned beetle spain’ and came across your site.
    Fantastic. I studied him for a while, taking loads of photos before letting him out onto my desk when he walked to the edge and fell off. Again afraid he might get hurt I scooped him up again, finally releasing him into what I hope is a safe area of my Alhaurin el Grande garden.
    Thanks for the information contained here, it was immensely interesting.

    PS Do we know if the horn has a purpose, or is it purely ‘ornamental’?

  4. Thank you for your story Ann, the beetles are great aren’t they? The beetles’impressive horns are indeed used for fighting and size and strength matters to their breeding success! If you have a healthy population of them you probably have the equally fascinating and large Mammoth Wasps too? (Black with yellow markings) The wasps parasitise the poor old beetles’ larvae.

    4th July 2015 – just found a poorly looking specimen in our street, minus one front leg. It now rests in our communal garden but I don’t think it will live long. We live in La Cala de Mijas, Costa del Sol and there are a few cork oaks still growing nearby, and of course, there are plenty of horses around!

  6. Aah, shame, poor old beetle- at least you rescued him and have given him a pleasant place to end his days! The beetles burrow into the ground when not rummaging in dung or otherwise roaming around, so you may never know whether or not he survived, but at least you’ll recognise him if he does resurface! Best wishes
