Yesterday I said I'll try to post something with longer note, so today I choose this shot. I hope you will find this post interesting.

The creature you can see on my photo is a caterpillar of moth that belong to Geometridae family.

These fellows can be easily named masters of camouflage in the world of buterflies. The exquisite camouflage of both caterpillar and adult stages is the reason for their evolutionary success.

The caterpillars are often called measuring worms, inchworms or loopers because of their quite exceptional way of walking. Even their latin name can be translated as "earth measurer". Why?
A geometrid caterpillar moves in alternate contractions and expansions suggestive of measuring. And it's quite hard not to notice such extraordinary view.

On the other hand you can hardly ever see them when they just sit still and not move. As I found out most of them pretend to be a twig and usually this is a twig of particular tree, so the camouflage is almost perfect. They have proper colours. Body seems to be quite stiff and some of them can raise themselves and stand on their claspers, sticking straight out at an angle, and so looking even more like a twig.
Usually they have special marks and structures on the body that resemble tree buds, texture of bark and any other features of twig.

On the photo you can see it quite clearly. I put there some close-ups and you must admit the camouflage of head as a bud is great.

I noticed this caterpillar only because I've been taking photo of other moth larvae (very hairy one) feeding on the same willow tree.
As for the ID. I think this could be Biston betularia known as Peppered Moth, but that's not 100% sure.

The catterpillars of this species can be found on oak, elm, birch and willow trees and the adult form has colours of birch bark and therefore they can be usually find sitting on the birch trunk.

Photos have been taken at the bank of pond behind my house. I had to use fill-in flash cause the BG was to bright and the caterpillar was in shadow.

Wow thatエs an excellent collage with great pictures and note. Congrats!. Great colours, lighting and excellent sharpness. A very nice composition. Thanks for posting.

Hello Monika :-)
To me it also seems that you have captured a caterpillar of Biston betularia (Linnaeus, 1758).

This is the famous peppered moth used in evolution books to illustrate so called industrial melanism and driving force of natural selection.

The species has two variants: dark and white. In industrial areas birch trees turn dark and the predators could easily catch white moths on dark trees, as a result of this action proportion of white moths decreased and the darker version became frequent...

Here the larva is on the willow, but there is a large variety of food plants for this species: Quercus spp., Betula spp., Ulmus spp., Fagus spp., Salix spp., Arbores fructiferae, etc.

And last but not least, in Polish the species is called Wlochacz nabrzozak :-)
Best greetings,

Monika, great shots, but where's the caterpillar? (LOL)

I do enjoy mimicry, and your shots show well how it happens. Congratulations.

I added your picture to a theme of mine.

Nice montage, well presented.

Excellent quality and presentation, on top of being really interesting. Instead of just jumbling a few shots together at random, you really show something here, and you show it very well indeed. WOW!!!
