ID pointers: Looks remarkably like a piece of plant stem, twig or tree bark. Has same flight time and habits as Pale Pinion, which needs to be carefully eliminated, especially dark forms.. The key feature is a tawny and blackish coloured tornal spot on the trailing edge of the forewing. A dark honey coloured crest on top of the head and narrow appearance to the wings with a straighter leading edge than Pale Pinion, with a less arched costa.
