Cryptic Camouflage

.
One of the examples of camouflage is cryptic camouflage or 'blending into the background'.

Cryptic camouflage is an attempt to blend into the environment and become effectively imperceptible. To do this, the camouflaged object must minimize observable differences between itself and the background with respect to the senses of the target observer.

The definitive example of camouflage is a cryptic camouflage designed to match the visual appearance of the expected background, generally using a mottled pattern of greens and browns to match ground and foliage color and break up the outline of the camouflaged object.

This Catocola Moth is Catocala maestosa. The pattern is very well adapted to dim lighting. This photo is a much clearer image than seen by the eye in the subdued light along the forest trail. My flash seems to bring out the colors and separate her(?) from the bark.

Discovered while on a trip to explore the Prairie Barrens at
Ft. Worth Nature Center & Refuge with Michelle Villafranca
The moth is the piece of bark in the center of the tree trunk between the vines.


The overall pattern simulates bark texture and grain.
Notice how the dark semicircles break up the overall wing shape,


An older name found in many books is Catocala viduata.

That's remarkable! Some insects are really clever at it.

Nice photos and explanation. I'm just starting to pay closer attention to the genus Catocola. I was disappointed not to see any in Arizona this year.

I have seen these around our property often. They like to find their way into our screened in porch. Nice shot.
