Adejeania vexatrix
In 3 days ~10% in a week ~20%
Adejeania vexatrix is a species of fly in the family Tachinidae. It is found in western North America from Mexico to British Columbia. In addition to its bright orange abdomen and prominent, heavy black setae, this species is noted for its greatly elongated palpi, which stick straight forward from under the fly's head. A similar looking tachinid fly, Hystricia abrupta, is found in the eastern United States. It does not have the elongated mouthparts of A. vexatrix. Paradejeania rutilioides also looks similar.

Rare
Under 5% of wildlife watchers report an Adejeania vexatrix sighting in Mexico City on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 413th 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 an Adejeania vexatrix in Mexico City on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Adejeania vexatrix 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 Adejeania vexatrix sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Adejeania vexatrix is recorded against all the insects logged in Mexico City (8 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.
