Cetonia aurata

Posted by Johan Dierckx (Wijnegem, Belgium) on 8 August 2010 in Animal & Insect and Portfolio.

Cetonia aurata (Gouden tor (BE) / Green rose chafer (EN) / Goldglänzende Rosenkäfer (DE) / Cétoine dorée (FR) ) is a beetle of the Scarabaeidae family, 20 mm long (which is large for a Belgian beetle !), that has metallic green coloration (but can be bronze, copper, violet, blue/black or grey) with a distinct V shaped scutellum, the small triangular area between the wing cases just below the thorax, and having several other irregular small white lines and marks. The underside is a coppery colour. The metallic gold/green colouring of the beetle's surface is the reflection of mostly left circularly polarised light. When viewed through a right circular polariser, they appear to be colourless. Rose chafers are mainly found over southern and central Europe, in Belgium they occur locally.

Hi Johan,
This looks amazingly similar to "Japanese Beetle" Popillia japonica ( http://bugguide.net/node/view/473 ) found here. Nice job showing the coloration.

@dang: Hi, Tom. Nice to hear something from you again. Hope everything is ok there ? I looked at the Japanese Beetle on that site and there are indeed some similarities. They belong to the same family so that is no big surprise. It seems to me that this Cetonia is much bigger: about 2 cm. It is one of the biggest that can be found in Belgium. Meeting this species is realy spectacular.

You captured both color and detail. Well done!

@Julie Brown: Sometimes it is very strange: you see something, make an image and the colour turns out to be (partly) gone ... I think you eventually expierienced that too. Untill now I have no good explannation for that and so not a sollution to overcome that problem. Maybe you have some suggestions?

@Mascha: De achtergrond zijn de geopende bloempjes van de distel (zoals die waar deze kever op zit). Op deze manier zie je toch nog stengel en bloem(suggestie) tegelijk :-). Bedankt alweer voor je mooi verwoord commentaar, Mascha.

I am glad my eyes aren't polarized. <-- it rhymes and isn't it the truth. I often dislike what has been taken with a polarizer on.. preferring the light I see with my eyes because that is how the the first impression of beauty is seen. Very nice that you've captured it naturally.

@Dutçh: Light is the most beautiful "thing" in nature... I'll always chase it, but it is so hard to catch... ;-) - oeps, tend to go the philosophical way now...

@simplyDoTa: I'm very glad you like this image.

daniela scharnowski from Berlin, Germany

I simply love it - the unusual (for you) perspective of the thistle, the bug, the fab background - just beautiful.
regarding your answer somewhere up - the human eye catches othes colours than the camera, would be my idea..

21 Aug 2010 1:45pm

@daniela scharnowski: Why you call this perspective unusual for me ? Makes me wonder ... do I have a usual perspective then? Tell me ! About colors: I think the human eye and the camera do catch the same colors but in a very different way, causing some problems of synchronisation between those two ...
