Male moths of Eldana saccharina Walker, in common with other gallerines, have a gland at the base of each fore wing. The gland has two parts; a main part consisting of large oval cells and a duct opening to the exterior via an orifice facing towards the wing tip, and a secondary part of which the duct does not open to the outside. Males also have prominent hair-pencils on the eighth abdominal segment. The hairs, which are inserted into large hooked secretory cells, are extruded past the outer surface of the claspers. These are themselves studded with large secretory cells, modified from trichogen celis. In the female, there is a small apparently secretory region of columnar cells with cylindrical hairs at the posterior edge of the seventh abdominal segment.
