oostelijke grashalmdansvlieg

Hybos grossipes

Unknown

Overview

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

The oostelijke grashalmdansvlieg faces severe habitat degradation due to intensive agricultural practices and urban development fragmenting its specialized grassland ecosystems. Pesticide use in agricultural areas directly impacts both the species and its prey base of small flying insects. Climate change is altering the moisture and temperature regimes of its preferred habitats, while habitat fragmentation isolates remaining populations and reduces genetic diversity.

Threat summary

Habitat

This dance fly species inhabits natural and semi-natural grasslands, particularly areas with tall grasses and herbaceous vegetation that support diverse insect communities. It requires undisturbed grassland ecosystems with adequate moisture levels and minimal chemical contamination.

Frequently asked questions

Why is oostelijke grashalmdansvlieg classified as Endangered?
