Feredayia graminosa is a common, native moth with a forewing length of 16- 19 mm. It is found throughout New Zealand. Moths are usually on the wing from September to January. They rest during the day and can be found on lichen covered tree trunks. They fly at night visiting flowers. They are attracted to light. 
Their wing pattern and the colour is a moss-like green, this camouflages them during the day. The male moths have long tufted, yellowish, vanilla scented scales on the undersides of each forewing and hindwings. It is presumed the wings help fan scent from the scales over female moths during courtship.
