Euroleon nostras
species of insect

Euroleon nostras is a species of antlion found over most of Europe. The scientific name can be translated as "our European [ant] lion". Adults resemble dragonflies or damselflies and may reach up to 30 mm (1.2 in) long, with a wingspan of 70 mm (2.8 in). The larvae prey on ants and other small creatures and require dry sandy soil in which to dig their pitfall traps.
Description
The larva of E. nostras has large jaws and a broad abdomen. When fully developed, which may take two years, it pupates under the soil, undergoes metamorphosis, emerging a month later as a much larger winged insect. The adult E. nostras is brown and resembles a dragonfly or damselfly in appearance. It is about 30 mm (1.2 in) long with a wingspan of about 70 mm (2.8 in). The four large translucent wings are spotted with brown.
Distribution
Euroleon nostras has a widespread distribution in Europe, and has been recorded from almost all European countries, its range extending from Spain through Germany to western Russia.

Why this record matters
“Euroleon nostras” is worth following because a concise public description often conceals a longer documentary argument. Here, Euroleon, nostras and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 3, 2025. The linked authority identifier is Q1317005. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
