Description: It is a small aquatic insect with a dorsoventrally flattened body and oval outline, well adapted for agile movement along the water surface and bottom. Coloration is generally dark or brownish-gray, with cryptic patterns that provide camouflage against muddy substrates and plant debris. The hind legs are modified for swimming, bearing dense setae that enhance propulsion.

Geographic distribution: It is mainly distributed across Europe and Western Asia, with records linked to lowland freshwater environments. Its occurrence is often localized, depending on habitat availability and water quality.

Habitat: It inhabits ponds, shallow lakes, temporary pools, and slow-moving waters, usually associated with submerged vegetation or organic matter on the bottom. It prefers calm, shallow waters that provide shelter and feeding opportunities.

Feeding: This species shows omnivorous feeding habits, consuming small aquatic invertebrates, insect larvae, microorganisms, and decomposing organic material. Such dietary flexibility allows it to persist in fluctuating environments.

Behavior: Activity is mostly diurnal, with individuals actively foraging. It can remain submerged for extended periods by trapping air beneath the wings and displays rapid escape responses when disturbed, often burrowing into the substrate.

Reproduction: Reproduction takes place in aquatic habitats. Females lay eggs attached to submerged substrates or aquatic vegetation. Development includes aquatic nymphal stages resembling adults, undergoing successive molts until maturity.

Conservation status: It has not been globally assessed in detail. Populations may be impacted by freshwater habitat degradation, pollution, and hydrological alterations.
