Telenomus dignus is approximately 1mm long.

Recorded hosts of T. dignus are mainly
What many of the recorded hosts of T. dignus have in common is that the eggs are covered by a protective layer of scales deposited by the female moth during oviposition.
Ovipositing female T. dignus may be attracted to egg masses with such a scale covering. Alternatively, it is possible that an egg mass of Spodoptera litura was mistaken for that of a Scirpophaga species (compare the following images:
Females probably mark each egg after oviposition as with most Telenomus species, and fecundity is likely to be variable under different conditions and between individuals (Polaszek & K., 2007).
