Papilio zelicaon, the Anise Swallowtail, is a common swallowtail butterfly of western North America. Both the upper and lower sides of its wings are black, but the upper wing has a broad yellow stripe across it, giving the butterfly an overall yellow appearance. There are striking blue spots on the rear edge of the rear wing, and the characteristic tails of the swallowtails. Its wingspan is 52–80 mm (2.0–3.1 in). Its body is somewhat shorter than the rather similar western tiger swallowtail, with which its range overlaps; it also lacks the black stripes, converging toward the tail, of the latter. There is a somewhat darker subspecies, P. z. nitra, which is rare throughout the range, though somewhat more often found at lower elevations.
The anise swallowtail has a wingspan ranging from 52 to 80 mm (2.0 to 3.1 in). Wings are mostly yellow, with black bands along the edges of both the forewings and hindwings. They are distinguished from tiger swallowtail butterflies by being smaller in size and lacking the vertical black striping patterns. There are yellowish-orange to red eyespots near the tails of each wing, each containing a black pupil. The body is predominantly black... Wikipedia →

Possible
About 20% of wildlife watchers report an Anise Swallowtail sighting in Tijuana on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 43 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report an Anise Swallowtail in Tijuana on a given day, against under 5% in October and December–February, the lowest months. That is one of Tijuana's driest months, with about 5 mm of rain against 55 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Anise Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 cities where we can rate Anise Swallowtail sightings, Tijuana ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in San Francisco (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Anise Swallowtail is recorded against all the insects logged in Tijuana (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.
