 Larvae of the Eastern forktail damselfly ("Ischnura verticalis)", larvae of skimmer dragonflies in the genus "Libellula" and adult water mites of the genus "Limnesia" have all been observed preying on "N. papillator".Both sexes of "Neumania papillator" are ambush predators - perching among the fronds of the aquatic vegetation, they hunt copepods (small crustaceans) which pass by in the water column.When hunting "N. papillator" adopts a characteristic stance termed the 'net stance' - their first four legs are held out into the water column, with their four hind legs resting on aquatic vegetation.
