Phocides polybius, the bloody spot or guava skipper, is a species of butterfly in the skipper family, Hesperiidae, that is native to the Americas. It is found from the lower Rio Grande Valley of southern Texas in the United States south through Mexico and Central America to Argentina. The species was first described by Johan Christian Fabricius in 1793.
The wingspan is 42–63 mm (1.7–2.5 in). There are several generations with adults on wing in February, April, and June to December in southern Texas. The larvae feed on Psidium species, including Psidium guajava and Psidium cattleianum. Adults probably feed on flower nectar. Wikipedia →

Possible
About 20% of wildlife watchers report a Southern Guava Skipper sighting in El Palmar National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 35 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Southern Guava Skipper is recorded against all the insects logged in El Palmar National Park (5 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.
