Automeris io, the Io moth (EYE-oh) or peacock moth, is a colorful North American moth in the family Saturniidae. The Io moth is also a member of the subfamily Hemileucinae. The name Io comes from Greek mythology in which Io was a mortal lover of Zeus. The Io moth ranges from the southeast corner of Manitoba and in the southern extremes of Ontario, Quebec, New Brunswick and Nova Scotia in Canada, and in the US it is found from Montana, North Dakota, South Dakota, Nebraska, Colorado, New Mexico, Texas, Utah, east of those states and down to the southern end of Florida. The species was first described by Johan Christian Fabricius in 1775.
Imagines (sexually mature, reproductive stage) have a wingspan of 2.5–3.5 inches (63–88 mm). This species is sexually dimorphic: males have bright yellow forewings, body, and legs, while females have reddish-brown to purple forewings, body, and legs. The males also have much bigger plumose (feathery) antennae than the females. Both males and females have one big black to bluish eyespot with some white in the center, on each hindwing. Some hybridizations have resulted in variations in these hindwing eyespots. Adults live 1–2 weeks... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Io Moth is recorded against all the insects logged in Monterrey (25 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.
