Syndemis musculana
Syndemis musculana is a moth of the family Tortricidae. It is found in Europe, China, the Korean Peninsula, Japan, Russia and North America.
The wingspan is 15–22 mm. The species lacks striking patterns and is also quite variable in colour, thus it is not easy to determine. The head, thoracic and forewing are more or less brownish grey. The forewing has a more or less distinct, wide, brown cross-band in the middle. The hindwings are light grey-brown.
The adults fly from April to July in the temperate parts of their range, such as Belgium and the Netherlands.
The caterpillars feed on oaks, birches, spruces, ragworts and Rubus. Less usually, they have been recorded to eat plant refuse and dry leaves.
