    Similar Species

    This species lacks any black stigmata on the forewing (present in M. metzneriella). Some of the Metzneria species have a similar ground colour but this is the only species with orange-red streaks. M. metzneriella can occasionally have strongly reddish-brown streaks but these do not have an orange tinge.
