Wings

The wings are greyish-brown color with white and black markings. Forewing is medially semi-translucent with prominent triangular white patch on costa. The apex is of pale chestnut color. Hindwing medially semi-translucent with dark grey-brown broder. The semi-translucent area of the hindwing has dark, poorly defined spot beneath it.
The length of the forewing is 22–27 mm.

Male

Followings are the characteristics of the male genitalia:

  • Uncus is truncated at apex (ventral view), extending beyond apex of the Valva.
  • The central element of Gnathos is small and short, not downcurved.
  • The apex of Valva is upcurved (i.e., dorsally).
  • Diaphragma densely denticulate.
  • Female

    The female genitalia has the following features:

  • Anal papillae is more rounded than pointed.
  • Anterior apophyses is weakly sclerotized.
  • Pocket present on Sternum 7 on each side of ostium bursae.
  • Antenna

    The antenna is not bipectinate in both sexes.

    Diagnosis

    M. hedylaria can be distinguished from M. cascaria by the presence of extensive semi-translucent areas on the wings and the prominent white triangular mark on the forewing. The pale chestnut brown color of the apex helps to distinguish M. hedylaria from M. conifera.
