Beautiful friend! Shame that it likely isn’t going to make it to adulthood after being parasitized. So it goes.

Here’s an adult of the same species for admiration:

Moth of the Week

Ornate Bella Moth

Utetheisa ornatrix

This moth was first described as Phalaena ornatrix and Phalaena bella by Carl Linnaeus in 1758. In 1960, it became known as the Utetheisa ornatrix by William Trowbridge Merrifield Forbes. It’s also called the ornate bella moth, ornate moth, bella moth or rattlebox moth and is in the family Erebidae.

Description The body is white with black spots on the back of the thorax and head. The legs are black and white and antennae are black and filiform. The hindwings are a pale or bright pink with an irregular black border. The forewings are orangish-yellow with white bands surrounding black dots. Patterns may vary. These colors are used to warn predators of the moth’s toxicity.

Wingspan range: 33 - 46 mm (1.3 - 1.8 in)

Diet and Habitat The larva feed on plants of the Crotalaria species such as Avon Park rattlebox, rabbitbells, smooth rattlebox, and showy rattlebox. These plants provide the larva and adults with alkaloid compounds which are the unpalatable to predators. They accumulate these toxins from the seed pods of these plants, however if the larva can’t eat a seed pod due to competition they will have to eat the leaves where is concentration is much lower. Larvae may prey on/eat others of its kind to maintain high levels of alkaloids. Alkaloids are also passed down from parents to eggs.

Its northern most range is from Connecticut westward to southeastern Nebraska and southward to southern New Mexico and Florida in the United States. Its southern most range is from Mexico, South America, and Central America. It’s southernmost reach is southeastern Brazil. This species is more common in tropical parts of this range due to host plant populations.

Mating This species demonstrates a form of sexual selection. The females choose a male to mate with based on the intensity of their pheromones. During mating, the females receive a “spermatophore” from the males containing sperm, nutrients, and alkaloid compounds. After mating, the females choose which males’ sperm fertilizes the eggs. Usually, the female chooses the male with the most alkaloids which tends to be the larger males. Adult males invest up to 11% of their body mass to create a spermatophore they provide to a female during mating. The nutrients given in the spermatophore allow the female to produce an average of 32 additional eggs in her brood.

Females mate an average of 4-5 times and up to 13 times, each with a different male. In the north there there two generations per year with more in the south.

Predators The larva and adults keep predators at bay with alkaloid compounds accumulated during feeding and inherited from parents. These toxins make them unpalatable to their main predators: spiders and bats. Specifically, the adult moth secretes an alkaloid foam from its head when threatened. However, larva and moths with low concentrations are more susceptible to predation than those with higher concentrations who are usually released and unharmed after being caught.

These toxins do not work against some predators like loggerhead shrikes.

Unlike other moths of the Arctiidae subfamily, this species moth does not have a way to audibly communicate their toxic which would help it to avoid bats altogether.

Fun Fact This species was first described on 1758 by Carl Linnaeus as two different species: Phalaena ornatrix was used to describe the paler moth specimens, and Phalanea bella, described the bright pink moth specimens. It was then moved to the genus Utetheisa in 1819 by Hübner. After nearly a century of struggling to identify this species and its subspecies, Forbes combined both species Utetheisa ornatrix and Utetheisa bella into one in 1960: Utetheisa ornatrix.

Quelites

El acuyo es hoja santa pimienta negra de India aroma y sitio perturbados por flores diminutas. Con él puedes envolver el corazón.

Chaya mansa domesticada no urticante cruda o en agua centro de consumos milenarios, quítame el azúcar, té medicinal.

La fortuna de las crotalarias es ser sonadoras. El chipilín y el chepil huelen a trébol a frescura leguminosa esencial.

El culantro y su ciclo bianual cortamente perenne simula repetir al cilantro picado salteado silvestre recao aromatico intensificador de Caribe.

Espontáneo frecuente la hoja el epazote condimenta lo inigualable. Su fin medicinal alargado aromático insustituible es el traspatio.

Para combatir lombrices pocas cosas como la infusión de hoja de aguacate. Anís delicado sabor de la tierra.

De familia de verbenas el matorral de orégano mexicano es agreste leñoso romerillo de monte oreganón y organillo. Muy loco.

A cítricos cilantro alcaparras huele el pápalo húmedo redondeado revoloteando al aire. De él brotan estrellas.

La pipícha es familiar inflorescente y pendular de cempasúchil. En suelo arenoso de frondas angostadas madura verdeazul púrpura y pardo.

En las hojas y tallos tiernos del amaranto moran semillas que en el comal revientan en alegrías. Así la floración del quintonil.

Desherbar verdolagas tiernas y carnosas. Volver a la maleza ensalada tallo suculenta jugosa ácida verdura anual.

do you have any fun science facts?

theres a plant i really like called Crotalaria cunninghamii!! it displays a really cool form of mimicry because it looks like a hummingbird!

ITS SO PRETTY scientists have a lot of hypotheses as to why theyre shaped like that, so theres not one like solid reason as to why (?)

some are thinking that its just human pattern recognition

some are thinking that its to ward of predators, or even lure in birds that would spread their seeds or help pollinate the plants

either way i think theyre really cool :] <3

Weeds Go Grrr: Rattlebox

Found this locally. It is very pretty.

It is also poisonous and invasive. 

Crotalaria spectabilis. Introduced from India into the Southeast the same reason a lot of other plants were, for adding nitrogen to the soil. It does that. It also kills anything unlucky enough to eat the seeds. 

See those lovely rattle-y pods? Don't eat them. 

Another look, so you can recognize the foliage too.

Lovely, but poison. Except, apparently, for larvae of the ornate moth, who use it for defense the same way monarchs use milkweeds. It's a similar heart-affecting toxin. Eep. 

Save us all from government types with "good ideas"....

#2107 - Utetheisa sp. - Rattlepod Moth

I've covered the two Utetheisa species most commonly seen in Australia before, but here's the caterpillar of one of them. Crotalaria plants are just one of the genera they eat, and are the reason the moths are called Rattlebox Moths, or in the case of U. lotrix the Crotalaria Moth, but the diet can be much wider. And still quite poisonous - the various species of rattlebox moths sequester alkaloids to protect themselves, and the males even use the poison in their pheremones, presumably to advertise how much they could tolerate as larvae.

At least some of the species migrate long distances, giving them native ranges that include remote islands.

Birdflower - Crotalaria Cunninghamii - Fabaceae Family

The Fun Facts

The Birdflower is also known as “Mangarr” by the Nyangumarta people of northwestern coast of Western Australia. They get their name as they look like hummingbirds, and whether what is an evolutionary tactic to protect themselves or just a coincidence is still unknown. These flowers grow from a perennial (a plant that lives for more then two years) shrub and grows 1-3 meters tall. The plant flowers from winter to spring and can grow in many different habitats, from arid and semi-arid zones of Western Australia and northern South Australia to the tropical areas of the Northern Territory and Queensland. Shrublands, grasslands and Savannah woodlands are their favourite habitats as Birdflowers prefer well drained soils. The Birdflower is predominantly bright green in colour with black lines running from the base of the flower to the tip, but can drift towards yellow and have hues of purple and red on the petals.

La Crotalaria juncea pertenece a la familia de las leguminosas y su principal uso es como abono verde; no obstante, también tiene un segundo uso como forraje. Es un cultivo que se debe sembrar en meses de temperaturas altas. No es muy exigente en cuanto a la calidad de los suelos, y las necesidades hídricas no son muy elevadas. Uso como abono verde: • Control de erosión hídrica y eólica. • Control de maleza. • Aumento de la macro y microporosidad del suelo. • Control de la población de distintos tipos de nematodos. • Gran fijación de nitrógeno. • Incorporación de materia orgánica de rápida mineralización. • Aumento de la fauna auxiliar.
