Cetonia aurata Linnaeus. Scarabaeidae. Cetoniidae.

Rose chafers are capable of very fast flight; they do it with their wing cases down thus resembling a bumble bee. They feed on flowers, nectar and pollen, in particular roses (from where they get their name); which is where they can be found on warm sunny days, between May and June/July, occasionally to September.

The larvae are C–shaped, have a very firm wrinkled hairy body, a very small head and tiny legs; they move on their backs, which is a very quick way to identify them. Larvae overwinter wherever they have been feeding, that is in compost, manure, leafmould or rotting wood, and they pupate in June/July. Some adult beetles might emerge in the autumn, but the main emergence is in the spring when they mate. Following mating, the females lay their eggs in decaying organic matter, and then die. Larvae grow very fast, and before the end of autumn they would all have moulted twice. They have a two year life cycle.

Rose chafers are found over southern and central Europe and the southern part of the UK where they seem to be sometimes very localized. They are a very beneficial saprophagous species (detritivore), their larvae are the insect equivalent of earth worms and help make very good compost where they are often found in great numbers.


The metallic green colouring of the beetle's surface is the reflection of mostly circularly polarised light, typically left circularly polarized light. When viewed through a right circular polariser, they appear to be colourless.[1] Many species of scarab beetles (scarabaeidae) are known to emit typically left circularly polarised light

Hello Josep,
A familiar Beetle that we've seen very little of here this summer so far. It's been so dry for weeks but last night we had a downpour so hopefully we'll soon see some more insects about! This is a beautiful composition showing this large Beetle clinging on to the flowers. Fine details and I like the colours.
TFS and cheers, Ulla

Ciao Josep Ignasi, bella Cetonia con ottimi dettagli, piacevole composizione con bello sfondo sfumato, bravo, buon week end, ciao Silvio

Hola Josep,

Buena captura, con buenos colores y buena composición. Además estás agregando exscelentes notas a tus trabajos.

La luz quedó justo en el punto aceptable. Revisa el setting de tu Canon, puede que andes algo pasado de ISO o... el sol en España seguro está de incencido ;-)

Saludos y abrazos,

Jesús

Hola Josep,
Muy buenos detalles y posición los capturados en esta foto. Suaves y dulces colores que contrastan con el caparazón del bichejo en cuestión. Bien hecho!
Un abrazo,
