Female Automeris io moth

"Automeris io, the Io moth (EYE-oh) or Peacock moth, is a colorful North American moth in the family Saturniidae [1]." from Automeris io

The io moth is also a member of the subfamily Hemileucinae [2]. The name Io comes from Greek mythology in which Io was a mortal lover of Zeus [3].

Distribution:[edit]

Male Automeris io moth

"The Io moth ranges from the southeast corner of Manitoba and in the southern extremes of Ontario, Quebec, New Brunswick and Nova Scotia in Canada, and in the US it is found from Montana, North Dakota, South Dakota, Nebraska, Colorado, New Mexico, Texas, Utah, east of those states and down to the southern end of Florida [4].

Article body[edit]

Adult Description: *Copied directly from Automeris io[edit]

"Imagines (sexually mature, reproductive stage) have a wingspan of 2.5–3.5 inches (63–88 mm) [4][2]. This species is sexually dimorphic, males having bright yellow forewings, body, and legs, while females have reddish-brown forewings, body, and legs [5]. The males also have much bigger plumose (feathery) antennae than the females[5]. There have been instances of gynandromorphism in io moths [6]. Both males and females have one big black to bluish eyespot with some white in the center, on each hindwing, a defense mechanism meant to frighten off potential predators, when the moth is sitting in the head-down position or touched [7][8]. Some hybridizations have resulted in variations in these hindwing eyespots[7]. Adults only live 1–2 weeks."

Parasitoids:[edit]

Many species of flies (Tachinidae) and wasps (Ichneumonidae and Braconidae) are known parasitoids [5]. The flies: the introduced Compsilura concinnata, Lespesia sabroskyi, Chetogena claripennis, Carcelia formosa, Sisyropa eudryae, Lespesia frenchii, and Nilea dimmocki [9][10]. The Ichneumonidae wasps: Hyposoter fugitivus and Enicospilus americanus [5]. Then the Braconidae wasps: Cotesia electrae and Cotesia hemileucae [5].

Predators:[edit]

Io moths have many predators. These include birds, small mammals, and spiders[5].

Defenses: *Only one sentence about this included in article[edit]

Stinging spines of caterpillar Io moths have a very painful venom that is released with the slightest touch; a condition known as erucism. There are two hypotheses regarding where this venom originates: (1) the glandular cells on the base of the branched seta or (2) from the secretory epithelial cells [11]. Contacting the seta is not life threatening for humans, but still causes irritation to the dermal tissue, thought to result in a stinging sensation [12][13].

Life Cycle from Automeris io:[edit]

*Note - not much editing required for this section, just need citations added:

There was an additional host plant found:

Erythrina herbacea, coral bean[14]

Lythrum salicaria, introduced Purple Loosestrife[15]

"The eggs have large micropyle rosettes that turn black as the fertile eggs develop. They are usually laid in clusters of more than twenty and hatch within 8-11 days[5]. From the eggs, orange larvae emerge, usually eating their egg shell soon after hatching [5]. They go through five instars, each one being a little different.

The caterpillars are gregarious in all their instars, many times traveling in single file processions all over the food plant [16][2]. As the larvae develop, they will lose their orange color and will turn bright green and urticating, having many spines. The green caterpillars have two lateral stripes, the upper one being bright red and the lower one being white. These caterpillars can reach sizes of 7 cm in length [1]. When the caterpillars are ready, they spin a flimsy, valveless cocoon made from a dark, coarse silk. Some larvae will crawl to the base of the tree and make their cocoons among leaf litter on the ground, while others will use living leaves to wrap their cocoons with [5][2]. The leaves will turn brown and fall to the ground during fall, taking the cocoons with them [5][2]. There they pupate, the pupa being dark brown/black [5]. The pupae also have sexual dimorphism with the females being considerably larger than the males [5].

Adult moths normally emerge from their cocoons in late morning or early afternoon. The emergence of the adult moths is typically from June to July [17]. Eclosion (emergence from the cocoon) only takes a few minutes [16]. After eclosing, the moths climb and hang on plants so that their furled wings can be inflated with fluid (hemolymph) pumped from the body. This inflation process takes about twenty minutes.

Adult moths are strictly nocturnal, generally flying during the peak hours of the night [17]. The females generally wait until nightfall and then extend a scent gland from the posterior region of the abdomen, in order attract males via wind-borne pheromones [5]. The males use their antennae to detect the pheromones. After mating, the females die following egg laying. These moths have vestigial mouthparts and do not eat in the adult stage [3][2]."

Conservation:[edit]

The io moth is currently not listed on the IUCN Red List or the US Federal List [16]. In the eastern range of the US, there have been populations that indicate a declining trend [18][16].
