Eutorna insidiosa is a moth in the family Depressariidae. It was described by Edward Meyrick in 1910. It is found in India (Assam).[1]
The wingspan is 10–13 mm. The forewings are deep ochreous with the costal edge blackish towards the base and with a broad ferruginous-brown streak beneath the fold from the base to the tornus, suffused beneath and posteriorly, edged above with some black scales and then with whitish suffusion. There is a triangular patch of ferruginous-brown suffusion extending on the costa from two-fifths to near the apex and reaching half across the wing, edged anteriorly by a very oblique ochreous-whitish streak preceded towards the costa by some blackish irroration, and enclosing a shorter similar streak from the costa at three-fourths, the second discal stigma is round and black, edged with ochreous whitish and there are some blackish scales along the termen. The hindwings are rather dark grey.[2]
