The moths reach a wingspan of 16-20 millimeters, and like all species of the genus Yponomeuta white wings on which many small, black dots are distributed. Head and forehead of the moths are pale gray, the sensor and the base member ( scape ) are gray. The labial palps are pale gray and turn dark. The thorax is grayish and provided with five black spots. The scales on the wing joint of the thorax ( tegulae ) are also pale gray and drawn, each with a black spot. The pale gray forewings have a drawing made of black spots, arranged in four rows. The first is located near the Costa charger and consists of three or four points in the Basalhälfte of the wing. The second row consists of three to six points, which are arranged below the Subcostalader. The third row runs along the alar fold and consists of five to eight points. The fourth row consists of three to eight points and extends below the wing fold. The hind wings are gray, legs and abdomen are pale gray.
The caterpillars reach a length of up to 18 millimeters and have a light blaugräuliche color, but the foremost and rearmost limbs have a distinctive yellow color. On both sides of the back there is a longitudinal row of larger black spots on the sides, there are other small black spots. The head is yellow.

Dissemination
The sedum Gespinstmotte is found only locally in England and Wales, here goes the distribution area to Lincolnshire and Worcestershire in the north. In Northumberland the species was also detected. In Europe, the sedum Gespinstmotte is widespread in the east the settlement area extends to China and Japan.
Way of life
One finds the sedum Gespinstmotte in forests and at the edges of fields. The caterpillars can be observed from June to July. The young caterpillars live as leaf miners, later larval stages live in groups in a slight web on the forage plants. They feed on sedum (Sedum ), which is why they have their name. Among the food crops include White Stonecrop (Sedum album), Large Stonecrop (Sedum telephium ) and closely related cultivars. Pupation takes place either in the Community or in the web of leaf litter in a thin but opaque cocoon instead, which is additionally coated with a second dream.
Flight times and caterpillars
The nocturnal moths that can be attracted by artificial light, fly in two generations from April to August, for England and Wales flight times from June to July and from September to October are given.
