The length of the forewing is 7 mm so the wingspan is about 14 mm.
No interactions present.
A key feature of Opostega salaciella is the pair of very large eye caps at the base of the antennae. These don't come across in the picture here. There is no indication of size which makes it difficult to start on many micro species. Elachista argentella is a possibility here.
The wingspan in certainly nearer to that for E. argentella.
