Description

Meyrick described the adults of this species as follows: The wingspan of this species is approximately 1 cm. In comparison to other species in the ''Sabatinca'' genus the forewing pattern of ''S. calliarcha'' is more complex and variable.

Distribution

Behaviour

Adults are on the wing from the end of September until the middle of January. Adult moths have been seen resting on algae covered stones where its wing colouration ensures it is well camouflaged. When disturbed it takes flight and comes to rest a short distance away. It is very difficult to see when on the wing.

Host species and habitat

Like other species in the genus ''Sabatinca'' the larvae of ''S. calliarcha'' likely feed on foliose
