Chondrostega vandalicia is a moth of the family Lasiocampidae. It is endemic to the Iberian Peninsula. Adult males have grey wings with a wingspan of about 15 millimetres (0.59 in). They are weak fliers. Females have reduced wings and are incapable of flight. Adult males are on the wing from August to September.
The larvae can be found from November to April and mainly feed on grass species such as Nardus stricta, Festuca and Anthoxanthum aristatum, but also other low growing plants such as Hypochaeris radicata. Wikipedia →

Rare
Under 5% of wildlife watchers report a Chondrostega vandalicia sighting in Sierra de Guadarrama National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 354th most-seen of the 597 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.

Only Sierra de Guadarrama National Park, in our data
Sierra de Guadarrama National Park is the only park on Wallace's Line with enough records to rate Chondrostega vandalicia sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Chondrostega vandalicia is recorded against all the insects logged in Sierra de Guadarrama National Park (10 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
