Overview

Chrysotoxum octomaculatum, the broken-banded wasp-hoverfly, is a species of hoverfly within the genus Chrysotoxum and family Syrphidae.

The Broken-banded Wasp-hoverfly faces significant threats from habitat loss and degradation due to agricultural intensification and urbanization across its European range. Climate change is altering the distribution and phenology of both the species and its host plants, while pesticide use in agricultural areas directly impacts populations and reduces prey availability.

Threat summary

Habitat

Inhabits flower-rich grasslands, meadows, woodland edges, and scrubland across Europe, particularly favoring areas with abundant umbelliferous plants and other nectar sources. Adults are typically found in semi-natural habitats including chalk downs, limestone grasslands, and forest clearings from lowland to montane elevations.
