Sometimes our roses seem to have something eating them aside from possums...not to worry; they're perfectly happy when transfered on to our Pohutukawa (Metrosideros excelsa) trees where they nibble distinctive and harmless half-moon chunks out of the leaves.
I've tried to emphasise their cryptic character here by neither adding flash nor spot-boosting contrast or acuity.
They can be remarkably large, easily spanning a hand's length, so are comfortable insect subjects for shorter focal length (~50mm) macro lenses (particularly on crop sensor Dslr's like my old D200 Nikon).
