Overview

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

The spotted antlion faces significant pressure from habitat degradation as sandy coastal dunes and heathlands are converted for development or altered by recreational activities. Climate change poses an additional threat through shifting precipitation patterns that affect the dry, sandy substrates essential for larval pit construction. Nitrogen deposition from agricultural runoff and air pollution alters the nutrient-poor soil chemistry that this species requires, while increased vegetation density reduces the open sandy patches needed for successful reproduction.

Threat summary

Habitat

Euroleon nostras inhabits dry, sandy coastal dunes, heathlands, and open sandy areas with sparse vegetation across northern and central Europe. The species requires well-drained, nutrient-poor sandy soils where larvae can construct their characteristic conical pits to trap prey.

Why is fläckig myrlejonslända classified as Vulnerable?
fläckig myrlejonslända is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The spotted antlion faces significant pressure from habitat degradation as sandy coastal dunes and heathlands are converted for development or altered by recreational activities. Climate change poses an additional threat through shifting precipitation patterns that affect the dry, sandy substrates essential for larval pit construction. Nitrogen deposition from agricultural runoff and air pollution alters the nutrient-poor soil chemistry that this species requires, while increased vegetation density reduces the open sandy patches needed for successful reproduction.
Where does fläckig myrlejonslända live?
fläckig myrlejonslända occurs in Austria, Belarus, Belgium, Bosnia & Herzegovina, Bulgaria, and Croatia (plus 29 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
