Vanessa atalanta, the red admiral or, previously, the red admirable, is a well-characterized, medium-sized butterfly with black wings, red bands, and white spots. It has a wingspan of about 2 inches (5 cm). It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The red admiral is widely distributed across temperate regions of North Africa, North America, Europe, Asia, and the Caribbean. It resides in warmer areas, but migrates north in spring and sometimes again in autumn. Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). The adult butterfly drinks from flowering plants like Buddleja and overripe fruit. Red admirals are territorial; females will only mate with males that hold territory. Males with superior flight abilities are more likely to successfully court females. It is known as an unusually calm butterfly, often allowing observation at a very close distance before flying away, also landing on and using humans as perches.

Possible
About 20% of wildlife watchers report a Red Admiral sighting in New York City on a given day, based on 1,966 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 1623 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.
May and July
In those months about 30% of wildlife watchers report a Red Admiral in New York City on a given day, against under 5% in December to March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Red Admiral sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
47th of 91

GBIF citizen-science records
It is estimated from how often the Red Admiral is recorded against all the insects logged in New York City (1,966 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.
