About the Ruby-Spotted Swallowtail

Papilio anchisiades, the ruby-spotted swallowtail or red-spotted swallowtail, is a butterfly of the family Papilionidae. It is found from southern Texas south to Argentina. Rare strays can be found up to Kansas, southeastern Arizona, and western Texas.

The wingspan is 70–100 mm.P. anchisiades. A widely distributed variable species. Hindwing posteriorly somewhat prolonged, less triangular; the tail is wanting or is only somewhat longer than the other marginal teeth, yet in the female sometimes as long and pointed as in the following species.

GBIF citizen-science records

It is estimated from how often the Ruby-Spotted Swallowtail is recorded against all the insects logged in Rio de Janeiro (6 verified sightings), calibrated against known sighting rates.
