With luck
About 10% of wildlife watchers report a Red Cracker sighting in Rio de Janeiro on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 169 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Red Cracker in Rio de Janeiro on a given day, against under 5% in January–February and July–November, the lowest months. That is one of Rio de Janeiro's driest months, with about 70 mm of rain against 230 mm in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red 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.

GBIF citizen-science records
It is estimated from how often the Red Cracker is recorded against all the insects logged in Rio de Janeiro (13 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.
