Oryctes nasicornis is a coleopter of the family of Scarabaeidae, subfamily of Dynastinae.
Oryctes nasicornis is widespread in all the Mediterranean basin Its length from 20 to 40 mm does of it one of the largest coleopters which meet in France.
At Oryctes nasicornis the sexual dimorphism is marked. The head of the male is surmounted by a long behind bent horn, from where its vernacular name of rhinoceros (rhino, nose; ceros, horn). The female is deprived of horn.
The larva is arched like that of the cockchafer (white worm). It develops in the vegetable matters in decomposition, nourishes wood (saproxylophage), woody remains generally not coniferous tree (except perhaps in the South-west of France). It lives between the ground and of wood in putrefaction, in the pourrissantes parts of old trees, in the compost, the heaps of compost and died sheets, the rebuses of the tanneries and the sawmills.
Arrival with maturity it reaches 60 mm, up to 100 mm according to certain authors. The duration of its development is 2 to 3 or 4 years. The size of the adult can be influenced by the quality and the abundance of food. The hyménoptère Scolia will flavifrons is a parasite of the larva.
The adult appears as of the end of March, April or May, and saw several months until autumn. One especially meets it during July and June. It is not very active, flies in the twilight and the night, attracted by the lights. Testing many difficulties of being restored when it falls to ground on the back, it can be watched for under the lampadères by the ants. It has for predatory the night raptors.

bonjour patrick
la note est tres interressante,bonne netteté,le point de vu n'est pas extra mais comme il avance tout le temps il est impossible de poser l'appareil et de faire la mise au point sur lui,en manuelle peut être!
beau specimen en tout cas.
laurent

Impressionnant specimen, auquel les galets font un bon background. L'angle de prise de vue est tres descriptif, il permet une excellente vision en trois dimension d'un insecte a la geographie tourmentee... Dommage qu'il y ait ce brin d'herbe!

  • Great

Great beetle, nicely sharp with nice natural colours. TFS

Karan

Bel insecte et pas si souvent sur TN.
Le fond est un peu trop present.
L'herbe devant est vraiment genante. Il aurait fallu la couper, replacer l'insecte et reshooter.
Tres net et detaille.
Merci.

Απίστευτο! Δεν θα μπορούσα να φανταστώ ποτέ ότι υπάρχει και σκαθάρι ρινόκερος.
