The Caterpillar of this species is expected to feed on dead leaves, as do others in this genus Eulechria, although different species in this genus seem each to prefer different host plants. The caterpillar probably lives in a tubular silk lined gallery, incorporating debris and frass, in amongst the dead leaves.

The caterpillar probably pupates in a larger and looser chamber at one end of the gallery.

The forewings of the adult moth of this species are white or sometimes yellow, with a bold brown sigmoid line and often also a chequered margin on each forewing. The hindwings are off-white, sometimes shading to brown at the margins. The wingspan is about 2 cms.

The species has been found in

  • New South Wales, and
  • Victoria.
