Dinoponera quadriceps
In 3 days ~30% in a week ~60%
Dinoponera quadriceps is a queenless species of ants in the subfamily Ponerinae. The species, known from Brazil, is similar to Dinoponera mutica and uses venom for subduing large live prey and defense. Its venom could be of use to the pharmaceutical industry.
Dinoponera quadriceps is found in the Caatingas, Cerrados, upland humid forest and Atlantic forest in the northeastern Brazilian states of Alagoas, Bahia, Ceará, Paraíba, Pernambuco and Rio Grande do Norte. Of all Dinoponera, Dinoponera quadriceps has the largest colonies with an average of 80 workers (range 26–238). Dinoponera quadriceps usually nest at the base of trees. Observations of Dinoponera quadriceps nests show that in more arid Caatinga and Cerrado habitats, nests are predominantly constructed under trees, whereas in Atlantic forest 60% of nests were 3 m away from any tree. Nests are deeper in Dinoponera quadriceps (and Dinoponera australis) than in Dinoponera gigantea, Monnin et al. (2003) suggests that deeper nests are a possible adaptation to seasons and aridity.
Workers of this species is recognized by its finely micro-sculptured integument which is not shiny, rounded anterior... Wikipedia →

With luck
About 10% of wildlife watchers report a Dinoponera quadriceps sighting in Fortaleza on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 112 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.
February and December
In those months about 30% of wildlife watchers report a Dinoponera quadriceps in Fortaleza on a given day, against under 5% in January, March–May, July–August and November, the lowest months.
Only Fortaleza, in our data

GBIF citizen-science records
It is estimated from how often the Dinoponera quadriceps is recorded against all the insects logged in Fortaleza (13 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.
