Rare
Under 5% of wildlife watchers report an Oblique Streaktail sighting in Mexico City on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 134th 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 30%, if each day is a fresh chance.
June to October
In those months about 10% of wildlife watchers report an Oblique Streaktail in Mexico City on a given day, against under 5% in November to May, the lowest months. Those are among Mexico City's wettest months, with about 130 mm of rain a month against 5 mm in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Oblique Streaktail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 25
Of the 25 cities where we can rate Oblique Streaktail sightings, Mexico City ranks 17th at under 5%. The best odds are in Sacramento (United States, about 20%), San Diego (United States, about 10%) and Los Angeles (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Oblique Streaktail is recorded against all the insects logged in Mexico City (56 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.
