Euphorbia palustris is pollinated by insects, mostly by Muscidae,Conopidae (flies). Typical pollinators also include syrphids, as well as beetles (Scarabidae,Dermestidae,Chrysomelidae, Cerambyicidae, Curculionidae, Elateridae),wasps(Braconidae, Tenthredinidae, Chrysididae), ants (Formicidae)and medium-tongued bees (Apidae).
Insects are attracted by the showy yellow nectar-glands and bracts forming the inflorescence. The nectar contains fructose,glucose and sucrose.
