Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Microvelia buenoi faces significant threats from habitat degradation and water pollution affecting its specialized aquatic environments. Urban development and agricultural runoff have contaminated many of the small streams and ponds where this water strider depends on surface tension for locomotion and feeding. Climate change-induced alterations to precipitation patterns threaten the delicate hydrological balance of its freshwater habitats, while invasive species may disrupt the invertebrate communities it relies upon for food.

Threat summary

Habitat

This water strider inhabits small freshwater streams, ponds, and slow-moving waterways with calm surface conditions essential for its surface-dwelling lifestyle. It requires clean water with stable invertebrate prey populations and vegetation along shorelines for shelter and reproduction.
