Desertas Wolf Spider

Hogna ingens

Declining

Overview

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

Hogna ingens faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Canary Islands. The species is particularly vulnerable to introduced predators and competitors, while its restricted distribution makes entire populations susceptible to local extinctions from natural disasters or human activities. Climate change poses additional pressure through altered precipitation patterns affecting the arid habitats this wolf spider depends upon.

Threat summary

Habitat

Hogna ingens inhabits arid and semi-arid volcanic landscapes in the Canary Islands, particularly favoring rocky outcrops, stone walls, and sparse vegetation areas. The species constructs burrows in sandy or loose soil substrates within these dry Mediterranean-type ecosystems.
