Thiodia citrana, the lemon bell, is a species of moth of the family Tortricidae.
It is found in China (Hebei, Xinjiang), Japan, Iran, Asia Minor, Turkmenistan, Russia, Kazakhstan, North Africa and Europe.
The palpi are relatively large and protrude in front of the head like a short beak.
The forewings are slightly pointed, pale yellow on colour, with small black cross spots along the costal edge.
They feed on the flowerheads of their host plant from within a spinning (a shelter like the web of a spider).
