Catocala neogama, the bride, is a moth in the family Erebidae first described by James Edward Smith in 1797. It is found in North America east of the Rocky Mountains, from Maine and Quebec south to northern Florida and west to South Dakota, New Mexico, and into Arizona and Texas. Its westernmost population from the semiarid Colorado Plateau region is rather distinct and was once considered a separate species, but is now regarded as a well-marked subspecies C. n. euphemia.
The wingspan is 70–85 mm; C. n. euphemia is distinctly larger (around 90 mm). The forewings are brownish gray above, evenly dark from base to tip or with the center somewhat darker, and varying geographically between somewhat paler and browner in the aridland population and darker gray marked with brown in the eastern individuals (see Gloger's rule). The hindwings are conspicuously colored in various hues of orange with roughly concentric black markings above. Their basal area carries a dense covering of thin dark hairs which stretches along the dorsum, making this area appear more brownish or reddish. Through the hindwing center runs a black band from the leading almost to the trailing... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bride Underwing sighting in Saguaro National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 300th most-seen of the 354 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.
August and September
In those months about 10% of wildlife watchers report a Bride Underwing in Saguaro National Park on a given day, against under 5% in October to July, the lowest months. Those are among Saguaro National Park's wettest months, with about 45 mm of rain a month against almost none in May.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Bride Underwing sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Bride Underwing sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Bride Underwing that you can see in Saguaro National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black Witch (about 10%), Merry Graphic Moth (about 10%) and Bird Toxonprucha (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bride Underwing is recorded against all the insects logged in Saguaro National Park (6 verified sightings from 2019 to 2026), 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.
