Messor structor
In 3 days ~20% in a week ~50%
Messor structor is a species of harvester ant belonging to the subfamily Myrmicinae native to the Mediterranean region and adjacent areas. It has been reported from southern Europe (e.g. Iberian Peninsula, France, Italy, Balkans) through North Africa and into western Asia. Its northern range reaches into the southern parts of Central Europe.
Messor structor is a large, seed-harvester ant with pronounced worker polymorphism. Workers range roughly 4–10 mm in length. The body color is typically dark brown to black; unlike some other Messor species, many M. structor workers have a distinctly brown hue. The exoskeleton is covered with relatively dense, stiff hairs or bristles.
M. structor typically inhabits dry, open habitats – especially sandy or steppe environments. It favors steppes, semi-deserts and sandy plains. Like other harvester ants, M. structor is mainly granivorous. Workers forage for and collect seeds throughout the warm season. They remove seed appendages before storing the seeds in the nest, which inhibits seed germination. Colonies can accumulate large seed stores, often 1–2 kg or more in underground chambers....

With luck
About 10% of wildlife watchers report a Messor structor sighting in Budapest on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 168th most-seen of the 404 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Messor structor in Budapest on a given day, against under 5% in September to February, the lowest months.

Of the 2 cities where we can rate Messor structor sightings, Budapest has the highest daily chance: about 10%. Next come Belgrade (Serbia, about 10%).
Same family: Formicidae
The closest relatives of the Messor structor that you can see in Budapest (family Formicidae, Ants) are Hairy Carpenter Ant (about 20%), Small-Headed Tree Ant (about 20%) and Eurasian Winter Ant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Messor structor is recorded against all the insects logged in Budapest (15 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.
