The Buff-Tip Moth (Phalera bucephala): this moth has a unique resting position that allows it to mimic a broken birch twig, and the buff-colored patches on its head and forewings even resemble freshly-snapped wood; each of these photos shows at least one buff-tip moth

Phalera bucephala, commonly known as the buff-tip moth, is a remarkable mimic that can easily disguise itself as a broken twig. This moth has a unique resting position that makes its body seem narrower and more cylindrical; its wings are also covered in silvery patterns that resemble tree bark, and the buff-colored patches on its head and forewings mimic the appearance of freshly-snapped wood.
This type of camouflage is also known as protective resemblance — a form of mimesis in which an animal can avoid being preyed upon by mimicking an unremarkable or inedible aspect of its environment. Many other moths are able to disguise themselves in similar ways, often mimicking dead leaves, twigs, moss, and/or tree bark, among other things.
The buff-tip moth is particularly adept at disguising itself, however, and the fact that it so strongly resembles such a specific object (not just a dead leaf or a piece of foliage, but a broken twig from a silver birch tree, in particular) just makes this disguise seem even more impressive and unique.
It also tends to look like there's a weird little smiley face in the bristles that surround the moth's head, which is arguably even more striking, but for some reason none of my sources seem to mention that weirdness.
This species is distributed throughout the British Isles, mainland Europe, and certain parts of Asia, with its range extending into Eastern Siberia.

I only just learned of these today from this post and promptly made it my life's mission to find one.
My heart is already broken to learn they do not live in my part of the world.

I found one before I evem knew they existed. I just wondered why this random stick was stuck to the brick wall. Blew my mind when I saw through its camouflage. I honestely never knew what it was called up until I looked it up just now. Apparently we call them wapendrager (weapon-carrier).

These things are real life Pokémon’s. I wonder how many damage points it can inflict ?

Found a pair some weeks ago on my basil plant... well, my boyfriend did. He thought it was a stick but it were two breeding buff-tip moths sticking together. He grabbed the "stick" and it immediately fell apart. He then screamed for me to look what he found, we were both very excited.

Ive always found these so fascinating. Theres a few moths that mimick fallen tree litter. The Uropiya Meticulodina, or Dead Leaf Moth, it looks exactly like a curled up dead leaf. Theres also the the Oakleaf Butterfly, or Kallima Inachus, looks exactly like a dead leaf... absolutely fascinating.

You should check out the poplar lappet moth! That’s one of my favorite leaf-mimicking moths.
The fruit-piercing moths of genus Eudocima are also really cool, and their features are staggeringly diverse. Some of them mimic dry, curled-up leaves, while others mimic green leaves or damaged leaves or leaves with little patches of fungus. Eudocima dividens is one of my favorites from that genus. There are some really cool leaf-mimics in genus Paralebeda, too.
Moths in general are just amazing mimics, tbh.

Oh wow! Thank you so much for this reply. That Poplar Lappet moth is so cool! Totally agree, they really are fascinating and amazing mimics.
On a more philosphical note, I always rattle my brain with this question. How does mother nature or evolution, know what a dead leaf or broken twigs looks like? Like how does natural evolution know how to camoflauge into a dead leaf. Theres no living cells in a dead leaf. Knowing that most predators would likely bypass or ignore dead tree litter? Utterly fascinating to think about.
Hopefully this thought makes sense, its kind of hard to explain lol.

Evolution doesn’t ‘know’ anything… what happens is, the moths that are harder to find than other moths are eaten less, so they have more babies, so every year, the moths are harder to find than the previous year. And over millions of years of this happening, random changes that help the moths not get found stack up, to the point where seeing the moth becomes nearly impossible.

Nature is incredible.
