Distoleon tetragrammicus is a species of antlion in the subfamily Myrmeleontinae. Distoleon tetragrammicus is widespread in the western Palearctic realm and it is present in most of Southern Europe and in North Africa. This species can be found in a wide range of habitats, from coastal dunes to mountain forests, mainly in arid and sandy areas, in oak and pine forests and in various calcareous wasteland with minimum moisture. The larvae avoid exposed sites as coastal dunes.
The adults of Distoleon tetragrammicus greatly resemble dragonflies or damselflies. They have a wingspan of about 75 millimetres (3.0 in). The front wing can reach a width of 26–40 millimetres (1.0–1.6 in). They have thick, prominent, apically clubbed antennae, a long, narrow abdomen and two pairs of long, transparent, multiveined wings, with some brown and opaque spots. This species is sometimes confused with Myrmeleon formicarius.

With luck
About 10% of wildlife watchers report a Four-Spotted Antlion sighting in Budapest on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 404 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Four-Spotted Antlion is recorded against all the insects logged in Budapest (32 verified sightings), 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.
