Longhorn Moths belong to the Adelidae family and unfortunately there is not much information to be found on them.
There are about 70 species in the region but this is the first one I have come across. It is a very tiny moth, hardly more than about 4mm in length.
They feed on flowers and the larvae of some of the species form meandering scribbles in leaves which increase in diameter as the larvae grows. Others make cases like small bagworms.
