Hypsopygia glaucinalis (Linnaeus, 1758)

Image ( Fig. 2b ): The larvae of this species live on dead and decaying vegetable matter of all types. The wingspan of the adults is 24mm. The antennae are filiform. The base color of the wing is pinky-brown. It bears two yellow transverse lines both on the fore and rear wings. The crossed lines on the costa of forewings are slightly widened, and the periphery line is slightly curved.

Tympanal organ ( Figs. 3b , 4b ): Bulla tympani is closed, round, and the inner edge is usually concave on the front. The praecinctorium, is undeveloped. The tympanum and conjunktivum are on the same plane. Tympanum is in a reverse “D” shape, and conjunktivum is in the shape of a thick “I”. The pons tympani is thin and in the shape of a needle, merging at the top. The fornix tympani is thick and elongated in the shape of a triangle downwards. The processus spiniforme is not prominent. The intersegmental thoraco abdominal membrane is in the shape of an indistinct “V”. The tergo-sternal sclerite is long and thin.
