Hamadryas iphthime, the ringless blue cracker or brownish cracker, is a species of cracker butterfly in the family Nymphalidae. It was first described by Henry Walter Bates in 1864. It is found in Mexico, Central America and parts of northern South America.
The wingspan of the ringless blue cracker is approximately 7.5 cm (3 in). The upper surface of the wings is mottled grey, brown and white. There is no red bar on the forewing and the hindwing has submarginal black spots, surrounded by blue, brown and blue rings, and with a central white crescent or oval. The under surface of the wings is whitish, with black rings near the hind margin that resemble those of Hamadryas feronia.
The larvae are black with fine longitudinal yellow lines, which may be indistinct, pale spines and two horns on the head. The pupae are bright green with some bands of white and a silvery rim to the yellowish-green wings. The heads of the pupae have a pair of elongated "rabbit ears", green with a white seam, forming a V-shape.
The range of the ringless blue cracker extends from Mexico, through Costa Rica and Panama, to Guyana, Colombia, Peru, Bolivia and southern... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brownish Cracker is recorded against all the insects logged in Lago de Yojoa (8 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.
