Common Bladderwort

The common bladderwort (<em>Utricularia vulgaris</em>) is a carnivorous aquatic plant belonging to the family Lentibulariaceae. It is classified as Near Threatened on the IUCN Red List, reflecting population declines linked to habitat loss and water quality degradation. The species has been recorded across diverse terrestrial tropical to temperate habitats in Belgium, Denmark, Norway, Sweden, and the United States. <em>Utricularia vulgaris</em> is typically found in slow-moving or still freshwater bodies such as ponds, lakes, ditches, and marshes. It is rootless and free-floating, with finely divided submerged stems bearing numerous small bladder-like traps that capture zooplankton, small aquatic invertebrates, and even mosquito larvae through a rapid suction mechanism. The plant produces yellow snapdragon-like flowers on emergent stems above the water surface during summer. Its carnivorous strategy allows it to supplement nutrients in nutrient-poor aquatic environments. Biological traits of this species remain poorly documented in the scientific literature.
