Life cycles of Dendritobilharzia loossi Skrjabin, 1924, a parasite of waterbirds, and its morphobiological traits are studied and described. Mollusks Anisus spirorbis, the infection rate of which in natural environments reaches 1.3-1.9%, were recorded as intermediate hosts under conditions of Uzbekistan. The development of this trematode in intermediate and definitive hosts lasts for 26 and 15 days, respectively. Diagnostic traits of the trematodes during all stages of their ontogeny are reviewed. Le cycle biologique de Dendritobilharzia loosi Skrjabin, 1924, parasite d’oiseaux aquatiques, et ses caractéristiques morphobiologiques sont étudiés et décrits. Le taux d’infestation naturelle du mollusque hôte intermédiaire Anisus spirorbis, qui atteint 1,3 à 1,9 % dans l’environnement, a été analysé en Ouzbekistan. Le développement de ce trématode dans les hôtes intermédiaires et définitifs dure respectivement 26 et 15 jours. Les étapes de l’ontogenèse de ce parasite sont passées en revue.
