With luck
About 10% of wildlife watchers report a Zilpa Longtail sighting in Monterrey on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 413 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Zilpa Longtail in Monterrey on a given day, against under 5% in December, the lowest month. That is one of Monterrey's wettest months, with about 200 mm of rain against 20 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Zilpa Longtail 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 Monterrey, in our data
Monterrey is the only city on Wallace's Line with enough records to rate Zilpa Longtail sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Zilpa Longtail is recorded against all the insects logged in Monterrey (58 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.
