Quagga Mussel
Dreissena rostriformis bugensis
This record describes Dreissena rostriformis bugensis (species). Recorded family: Dreissenidae. Recorded order: Veneroida.
Identification and Appearance
This invasive bivalve is typically 2-5cm in length, often with zig-zag brown stripes, though can be solid brown. Adults attach to hard substrata such as rocks, wood, man-made piping and can smother native mussels. It has a high filtering capacity and grows in dense populations so can significantly reduce native biodiversity and alter whole freshwater ecosystems. It is also a nuisance and economic problem when growing water treatment pipes. Zebra Mussels are very similar but have a flattened bottom and can sit upright on a flat surface, whereas Quagga Mussels have a rounded, asymmetrical edge and will tip over on their side. All year - often empty shells can be found at the water's edge. Locally abundant and common at Rutland Water. No additional images available for this species.

About Veneroida: the wider group
Order-level background for Veneroida, the group containing Dreissena rostriformis bugensis. Species-specific details appear above.
Group overview
This is a smaller arthropod order with specialized ecological roles. Arthropods are the most diverse animal phylum, comprising over 80% of all known animal species with approximately 1.2 million described species globally.
Ecological role of the group
Members of this order contribute to broader arthropod ecosystem functions including decomposition, predation, and serving as food sources for vertebrates. Arthropod biodiversity is essential for ecosystem resilience.
Economic and practical significance of the group
While this order has limited direct economic impact, arthropods collectively provide ecosystem services worth trillions of dollars annually through pollination, decomposition, pest control, and nutrient cycling.
