Garrha sericata is a moth in the family Oecophoridae.

[1] It is found in Australia, where it has been recorded from Queensland and New South Wales.

The forewings are uniform whitish-grey, faintly ochreous-tinged and with a whitish costal edge.

There is a very fine transverse row of dark grey scales from the middle of the costa to the inner margin before the anal angle, irregularly sinuate on the upper half and strongly angulated in the middle.

A row of conspicuous black dots is located on the hindmargin and apical fifth of the costa.
