A picture from the pre-digital-era.

Not nice but bizarre, that's the appearance of this last instar caterpillar of the moth Selenia dentaria (= bilunaria) of the family Geometridae. By its colour and also by the bearing, the larva succesfully imitates a twig. There is a chance to discover it when it moves by the usual geometride mode by forming a bow (picture) and subsequent stretching. During balancing on twigs the larva produces a security line which is also seen on the picture. The larva feeds on various trees and bushes such as Salix, Quercus, Betula, Rosa and Viburnum.
The species is wide-spread in the palaearctic region, from western Europe to Kamtchatka in the east.

An auto-bellows was used in addition to the lens.

Diapositive scanned with Reflecta Silver, 1800 dpi.

Hello Peter,
Very nice capture.Well seen and composed.POV,use of light,details and framing are wonderful.

How strange indeed ! If the beast is not exactly attractive, the picture is indeed excellent and informative.

Very impressive sample of camouflage, Peter.

Hallo Peter,
ich glaub nicht dass ich die Raupe gesehen haette die hat sich ja wirklich super getarnt.
Super Nahaufnahme; Perspektive Schaerfe und Details sind einwandfrei.

Hallo Peter, das zeigst Du uns aber etwas Besonderes. Erst einmal ist das Motiv mit dieser Raupe schon einmal super. Das eingescannte Dia ist auch in digitaler Form sehr gut geworden. Da kommen mir direkt die Erinnerungen an mein Balgengerät wieder hoch, daß meine Töchter damals, war auch so Ende der 80er, zerlegt hatten. - Dein Foto ist super, sehr gute Schärfe, Bildgestaltung und natürliche Farben. Danke Dir für dieses alte Foto.

Pre-digital iindeed -- by a long way. This is quite an amazing pose in which you've caught this character. Terrific POV and dof with nothing to distract in the background.
And remarkable quality for a scan.

Great image in this pose. Everything is great about the photo, but I think there is an off color cast - perhaps something to do with white balance during the scan - a bit of warming would bring it back.

Unlike monarch butterflies, this one is not cute at all. Still, it is an interesting subject that most people would overlook or will never encounter. It is well photographed with sharp details on a neutral background. Beautiful. The note is informative. That's what TN is all about. TFS, Peter.
