Zygaena loti
In 3 days ~20% in a week ~50%
Zygaena loti, the slender Scotch burnet, is a moth of the family Zygaenidae. It is a diurnal moth characterized by a black body, light colored legs, and red spots on its wings. The caterpillars are a yellow-green color and usually molt out of dormancy in late February to early March. The larvae feed on plants from the family Fabaceae until they enter their pupal stage and mature into adults in May to early June. For mating, Zygaenidae exhibit a dual-partner finding strategy, where females use pheromones while assuming a calling position, and males exhibit a patrolling behavior where they utilize both vision and the olfactory receptors in their antennae to locate a potential mate.
Although regionally endangered as their population is declining, Z. loti is found all across Europe, inhabiting areas rich in their desired food plants: lime-rich, and characterized by a hot and dry climate. The decreases in their population are likely due to factors such as habitat loss and fragmentation brought on by commercial agriculture and urbanization, as well as global climate change. There are few conservation programs currently focusing on Zygaena loti.

GBIF citizen-science records
It is estimated from how often the Slender Scotch Burnet is recorded against all the insects logged in Ecrins National Park (8 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.
