About the Soldier

Danaus eresimus, the soldier or tropical queen, is a North American, Caribbean, and South American butterfly in the family Nymphalidae. Their flight is slow and they are reasonably easy to approach, but will fly for some distance if approached too closely.

The upperside of the wings is dark reddish brown with the forewing sometimes having white submarginal spots. The veins are lightly marked with black. Males have a black scent patch on each of the hindwings. The underside of the wings is also dark brown with a postmedian band made up of squarish spots. The soldier has a wingspan of 2+1⁄2 to 3+1⁄2 inches (64–76 mm). D. e. flexaure, formerly D. flexaure, is a subspecies which has more white markings on the hindwing underside.

Similar species in the soldier's range include the monarch (Danaus plexippus) and the queen (Danaus gilippus). The monarch is more orange, has heavier black-lined veins, and the underside of the wings is a pale yellowish color.

The queen has nearly no black-marked veins, and has white forewing submarginal spots on both surfaces of the wings. The soldier may be found in a variety of open, subtropical habitats... Wikipedia →

Where does the Soldier sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Soldier is recorded against all the insects logged in Buenos Aires (9 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.
