The Common Marbled Carpet (Chloroclysta truncata) is a moth of the family Geometridae. It is very common throughout Europe including the British Isles.
This is one of the most variable of the Geometrids both in size (wingspan 32-39 mm) and colour. The basal and terminal areas of the forewings are marked with fascia separated by a large plain area in the middle, but the colouration of all these areas is confusingly variable from white to black with various grey, brown and reddish tones in between. The hindwings, though, are always pale grey marked with faint fascia. One or two broods are produced each year and the adults can be seen in any month from May to November. The species flies at night and is attracted to light. It is also attracted to nectar-rich flowers and sugary foods which is fairly unusual for the family.
The larva is slender and green, usually with reddish stripes. It has been recorded feeding on a wide range of plants including: bilberry, birch, bramble, dock, hawthorn, privet, rose, sallow and strawberry. The species overwinters as a larva.
