Rare
Under 5% of wildlife watchers report a Davis' Tussock Moth sighting in Mexico City on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 352nd 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Davis' Tussock Moth in Mexico City on a given day, so our monthly data shows no clear season.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Davis' Tussock Moth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Davis' Tussock Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Davis' Tussock Moth is recorded against all the insects logged in Mexico City (11 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.
