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.
The larvae do not look anything like adults. The length of a fully grown larva is typically 12–22 millimetres (0.47–0.87 in). The basic body color is dark brown with darker markings. The head is dark brown. The strong dark brown mandibles... Wikipedia →

With luck
About 10% of wildlife watchers report a Four-Spotted Antlion sighting in Cévennes National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 996 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Four-Spotted Antlion in Cévennes National Park on a given day, against under 5% in October to June, the lowest months. That is one of Cévennes National Park's driest months, with about 35 mm of rain against 260 mm in October.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Four-Spotted Antlion sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 4 parks where we can rate Four-Spotted Antlion sightings, Cévennes National Park has the highest daily chance: about 10%. Next come Sierra Nevada National Park (Spain, about 10%) and Pyrénées National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Four-Spotted Antlion is recorded against all the insects logged in Cévennes National Park (42 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.
