Possible
About 20% of wildlife watchers report a Gray Cracker sighting in Recife on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 67 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.
May
In that month about 40% of wildlife watchers report a Gray Cracker in Recife on a given day, against under 5% in August–October and December–January, the lowest months. That is one of Recife's wettest months, with about 200 mm of rain against 25 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Gray Cracker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 22 cities where we can rate Gray Cracker sightings, Recife ranks 4th at about 20%, level with the leaders once rounded. The best odds are in San Pedro Sula (Honduras, about 20%), Santa Cruz de la Sierra (Bolivia, about 20%) and Santo Domingo (Dominican Republic, about 20%).
Same family: Nymphalidae
The closest relatives of the Gray Cracker that you can see in Recife (family Nymphalidae, Brush-footed Butterflies) are White Peacock (about 30%), Mexican Fritillary (about 30%) and Dirce Beauty (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray Cracker is recorded against all the insects logged in Recife (14 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.
