The species occurs throughout almost the whole of Europe. In the north, the range extends to Middle Fennoscandia, in the east to the Urals. The species occurs in North Africa, Asia minor, Syria, Iraq, Iran, Caucasus, Central Asia to China, Korea and Japan (subspecies C. t. exigua (Butler, 1881)). It rises in the Alps up to 1600 m.

Description
For a key to the terms used, see Glossary of entomology terms.

This is a very variable species, both in size (wingspan 28–38 mm) and colour. The ground colour of the forewings varies from pale buff to dark or reddish brown with three narrow fascia. The area between the inner two fascia is sometimes much darker than the surrounding ground colour and is marked with stigmata, often quite indistinct. Melanic forms occasionally occur. The hindwings vary from pale cream to dingy brown. This moth flies at night from July to September and is attracted to light and sugar and sometimes to nectar-rich flowers.

The larva is green with yellow lines and black and white spots. It feeds on a variety of plants, chiefly trees and shrubs (see list below) and also on the larvae of other Lepidoptera species, even occasionally its own species. The species overwinters as an egg.

gollark: Yeeees, American healthcare does seem to be uniquely bizarre and wasteful. There are a bunch of theories about this.
gollark: (there are probably, at most, something like a thousand offices getting that)
gollark: This furniture budget thing probably doesn't add up to a significant amount of the total spend, so it's a bad comparison.
gollark: Apparently American healthcare spending is something like 17% of GDP for some insane reason. So it would be a big fraction of the government budget, if they ran it as efficiently as it currently operated.
gollark: Possibly. Paying people if they want to move out seems more reasonable than doing stupid things to local property markets, or whatever, or adjusting taxes so those already there can afford it.
