Distribution


Imago

Wingspan 14–19 mm. The species is very variable in coloration and here is often a greenish or olive tinge to some of the markings. Well-marked specimens of Z.isertana may be distinguished by the comparatively small and usually trapezoidal blotch of (pale) ground colour on the dorsum of the forewing, but it can be obscured too.
