Utetheisa ornatrix, also called the ornate bella moth, ornate moth, bella moth or rattlebox moth, is a moth of the subfamily Arctiinae. It is aposematically colored ranging from pink, red, orange and yellow to white coloration with black markings arranged in varying patterns on its wings. It has a wingspan of 33–46 mm. Moths reside in temperate midwestern and eastern North America as well as throughout Mexico and other parts of Central America. Unlike most moths, the bella moth is diurnal. Formerly, the bella moth or beautiful utetheisa of temperate eastern North America was separated as Utetheisa bella. Now it is united with the bella moth in Utetheisa ornatrix.
The larvae usually feed on Crotalaria species, which contain poisonous alkaloid compounds that render them unpalatable to most predators. Larvae may prey on other bella moth larvae in order to compensate for any alkaloid deficiency.
The bella moth also demonstrates complex mating strategies and is thus an excellent model to study sexual selection. Females mate multiply and receive spermatophores containing sperm, nutrients and alkaloid compounds from numerous males as nuptial gifts. Females choose males according to the intensity of a courtship pheromone, hydroxydanaidal, and carry out a sperm selection process after copulation with various males. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ornate Bella Moth sighting in Guadalajara on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 117th most-seen of the 229 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January and October–November
In those months about 10% of wildlife watchers report an Ornate Bella Moth in Guadalajara on a given day, against under 5% in February–September and December, the lowest months. Those are among Guadalajara's driest months, with about 25 mm of rain a month against 210 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ornate Bella Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 14
Of the 14 cities where we can rate Ornate Bella Moth sightings, Guadalajara ranks 11th at under 5%. The best odds are in Recife (Brazil, about 20%), João Pessoa (Brazil, about 10%) and Salvador (Brazil, about 10%).
Same family: Erebidae
The closest relatives of the Ornate Bella Moth that you can see in Guadalajara (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black Witch (about 10%), Eucereon myrina (about 10%) and Hieroglyphic Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ornate Bella Moth is recorded against all the insects logged in Guadalajara (14 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.
