Helophilus hybridus · žiedmusė

- Helle Sumpfschwebfliege

- gniłun kwieciak
It is a Palearctic species. Habitat: around pond and ditch margins where the water is shallow, and submerged grass grows on the blackish mud. The aquatic rat-tailed larvae have been recorded feeding on the decaying rhizomes of Bulrush.
Females resemble a large, buffish H. pendulus but the hind tibiae are only yellowish in the basal third. Males are more distinctive with large, continuous panels of buff occupying the sides of tergites 2 and 3. The black facial stripe readily separates it from H. trivittatus.
