The adult insect has a wingspan of about ,][ with wings that are mostly clear, but have many dark spots or patches. Its head, mounted with large eyes, is drawn into a prominent, downward pointing beak,][ which opens at the tip of its head. Females are longer, heavier, and have longer legs than males.
In the female, the eighth abdominal segment is the shortest, almost twice shorter than the seventh; the sixth is narrowed towards the back.

Mating behavior
Males release pheromones and offer nuptial gifts to females in the form of saliva secretions and nuptial prey (usually dead arthropods). Before offering the nuptial gifts, the male and female, perform ritualized premating behavior, which includes slow wing movements, accompanied by brief sequences of rapid vibrations from their abdomen. The mating success of females increases with the size of nuptial gifts offered by the male.
