This Asian species was first recorded in Belgium in 2011 in OV.
At the time, these were adventive specimens that were found in a shop where the foodplant was for sale. It has since then been shown that this species can reproduce in gardens with ponds where the foodplant is present.
When disturbed, both sexes show a conspicuous rapid waving with the hind legs. This very obvious behaviour can continue for 5 or more minutes.
The diurnal moths are on the wing from late May towards September.
The larva lives only on Acorus calamus.
Ponds, swamps where the foodplant occurs, even in small quantities.
