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 Chicago on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 538th most-seen of the 978 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 Bride Underwing in Chicago on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 10 cities where we can rate Bride Underwing sightings, Chicago ranks 8th at under 5%, level with the leaders once rounded. The best odds are in Toronto (Canada, under 5%), Minneapolis [Saint Paul] (United States, under 5%) and Salt Lake City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Bride Underwing is recorded against all the insects logged in Chicago (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.
