Rare
Under 5% of wildlife watchers report a Guatemalan Cracker sighting in Mexico City on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 268th most-seen of the 557 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Guatemalan Cracker in Mexico City on a given day, against under 5% in January to November, the lowest months. That is one of Mexico City's driest months, with about 5 mm of rain against 150 mm in July.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Guatemalan 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.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Guatemalan Cracker sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Guatemalan Cracker that you can see in Mexico City (family Nymphalidae, Brush-footed Butterflies) are Juno Silverspot (about 20%), West Coast Lady (about 20%) and Monarch (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guatemalan Cracker is recorded against all the insects logged in Mexico City (19 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.
