Moths

Luna Moth

William-Perry_luna-moth_Actias luna
Family: Saturniidae

Wingspan: 12 cm, with 6 cm tails
Description:
pale green, pink-edged wings with long tails, transparent spot on each wing, those on forewing joined by dark line to wing edge
Larva:
up to 85 mm long; bright green with sparse hairs; each segment with widely-spaced reddish spots
Range:
throughout south and central Ontario, north to nearly James Bay
Habitat: forested areasLarval foodplants:  birch preferred, but also walnut and several other species
Flight season: mid May to July
Overwintering stage: cocoon
True fact: Male giant silkmoths like luna, polyphemus and cecropia have much larger antennae than their female counterparts.  These are used to detect pheromones emitted by females; the males can track this seductive “perfume” over one kilometre to its source during breeding season.

Polyphemus Moth

Polyphemous moth by Cathy KeiferAntheraea polyphemus
Family: Saturniidae

Wingspan: 110 – 150 mm
Description:
wings generally rich brown colour, oval transparent spot on each of four wings ringed by yellow, black and blue, those on hind wings also surrounded by large bluish-black patch; crescent-shaped pink and white marks near base of forewing, pink to brownish line near edges of forewing
Larva:
up to 80 mm, bright green, with sparse protruding hairs and yellow streaks and reddish spots on sides.
Range:
throughout the southern and central part of our province, north to James Bay
Habitat:
forested areas
Larval foodplants:
many trees, including oak, birch, ash, grape, hickory, maple
Flight season:
mid May to July
Overwintering stage:
cocoon, resembles a silken egg wrapped in leaves
True fact:
Due to its large eyespots, this moth is named after the Cyclops Polyphemus (a one-eyed monster) that Homer encountered during his odyssey.  Like other giant silkmoths and the imperial moth, adult Polyphemus moths do not eat as adults, living only a week or two to mate and begin the next generation, literally starving to death in the process.

Cecropia Moth

Cecropia mothHyalophoa cecropia
Family:Saturniidae

Wingspan: 110 – 160 mm
Description: our largest moth.  Red body banded with white on abdomen, also white collar.  Rich brown wings with reddish bases, white crescent-shaped eyespots on all wings lined with red and black, white band spans each wing beyond eyespot.
Larva: robust, up to 100 mm.  Green with two pairs of red spiny tubercles on thorax, two rows of blue spiny tubercles on sides, and two rows of yellow spiny tubercles down back.
Range:
southern and central Ontario
Habitat:
successional areas, including suburban and urban environments
Larval foodplants:
many trees and shrubs, including birch, lilac, cherry, apple, willow, ashes and elms among others.
Flight season:
late May to July
Overwintering stage:
Cocoon spun on branches
True fact:
The silken cocoon of our giant silkmoths (cecropia, luna, polyphemus and others) can be used to make clothing, but are much more difficult to unravel than the cocoons of the Chinese silkworm moth, which produces virtually all commercial silk.

Imperial Moth

Imperial mothEacles Imperialis
Family: Saturniidae

Wingspan: 80 – 170 mm
Description:
a large moth with a heavy body, yellow wings variably shaded with pinkish to purplish patches and similarly coloured dots on hindwing, body pinkish to purplish overlying yellow
Larva:
up to 100 mm; green, sparsely haired, black-edged white spots on side, four orange tubercles on top of thorax
Range:
throughout southern and central Ontario, north to northern Lake Huron and Ottawa area
Habitat:
deciduous, mixed and coniferous forest
Larval foodplants:
mainly pine, maple, oak, sycamore, sweetgum
Flight season:
June to August
Overwintering stage:
pupa in the soil
True fact:
This species is dimorphic, with the female being larger and usually yellower than the male.  A pine-eating subspecies, called the pine imperial moth, occurs in the northern parts of this widespread moth’s range, and is most commonly encountered in Canadian Shield areas.

Ilia Underwing Mothilia_underwing_moth_credit_attribute_sharealike_johnx12_v2

Catocala Ilia
Family: Noctuidae

Wingspan: 65 – 80 mm
Description:
forewing mottled grey; may have white spot on forewing, hindwing alternating orange to pinkish orange and black bands, edged with yellow.

Larvae – a stout, lime to yellowish green caterpillar with a bluish coloured curved horn on its back at the posterior end; a light yellow stripe runs along the sides to the horn; the spiracles (openings to the respiratory system on either side) are white with orange to pink borders; also known as a hornworm
Foodplants:
Larvae – viburnums, hawthorns, honeysuckles, snowberry, cherries, plums

    Have recently seen the White Admiral and Giant Swallowtail butterflies in Eastern Ontario.

    Thanks for posting this! I’ve found it very useful in identifying our local butterflies and moths. We’ve had the following pass through our yard in Singhampton, On this week. Some attracted by the last few wildflowers and others by the sap from our birch tree oozing from sapsucker holes.

    Monarch
    Mourning Cloak
    Eastern Tiger Swallowtail
    Great Spangled Fritillary
    Question Mark
    Red Admiral

    This is a great site, thank you! I saw a cecropia but had no idea at the time what it was. Beautiful and extremely large.

    My father said that he saw and captured a butterfly the flow like a hummingbird and had black wings and circle white dots and he is getting old so I want to tell him the species of butterfly he had saw back then. If you look for this kind of butterfly this is maybe it is an extinct species because he said that was the only butterfly that flow and looked like that I have got a picture that I showed to him and he said “That what it looked like.” And I was pretty happy with that just I need to know what it is please help the clock is ticking.

    Hi Tyler,

    Thank you for asking!

    Would the butterfly have been a white admiral butterfly: http://www.cbif.gc.ca/eng/species-bank/butterflies-of-canada/white-admiral-red-spotted-purple/?id=1370403265814

    or a black swallowtail butterfly:
    http://www.cbif.gc.ca/eng/species-bank/butterflies-of-canada/black-swallowtail/?id=1370403265551

    perhaps a hummingbird moth: http://onnaturemagazine.com/butterfly-and-moth-guide.html#hummingbird

    or even a silver-spotted skipper?: http://onnaturemagazine.com/butterfly-and-moth-guide.html/4#silver-spotted

    It is hard to say without seeing a photo of the species or the butterfly itself, but based on your description I thought the above links would provide the most potentially helpful resources.

    I found a brown luna moth north of baltimore . lots of woods.

  7. April 21, 2016    

    Hello B,

    That is wild!

    Was it is a Polyphemus moth: http://onnaturemagazine.com/butterfly-and-moth-guide.html#polyphemus ?

    Or did it have tail-like extensions on its wings like the luna moth?

    Best,

    ON Noah

    PS. If you do have photos to share, we’d love to see them all the same!

    Your site is very difficult to read. The top title literally takes up half my screen sand does not go away so it’s like I’m scrolling constantly within a tiny little scrollable area to see the pictures of the moths. Except for the ONnatur…. everything is white on pale something, or pale something on white. It’s hard to read!

    Not a friendly usable design at all.

    My mom spotted what looked like a hummingbird working my catmint blooms today. At first glance we wondered if it was a baby hummingbird. Further search and your website brought us to the answer…… a hummingbird clearwing. First time spotting such a thing. What an awesome creature!

    We found a moth yesterday that looked like a Dragon. It was very dark, had wings that were bat shaped, a long curling talon and what looked like yellow talons”. What on earth is that????

    Good info thank you, Was recently in Saskatchewan north near LacLaronge and was out having a smoke at 2am and while sitting in the gazebo my attention was drawn to a HUGE moth or butterfly kinda looked like the luna moth but was a more vivid green colour it seemed to be trying to eat or investigate a cocoon on the wall it was flapping like mad going up and down the wall the few times it settled down it seemed to rest with wings up so i think butterfly but i don’t know for sure what i saw it was BIG BIG BIG Though.

    Hi Kristi,

    Could it have been a species of sphinx moth? Sphinx moths have similar characteristics to those you described.

    Hi I just wanted to report that I have giant swallowtail catnipillars on my hop tree and also lots of painted ladies laying eggs on my pearly everlasting plants. Sadly here in Guelph I have not seen a single monarch this year on my large patch of milkweeds so sad. Also I have hummingbird moths nectaring on my liatris and bergamot they are especially fond of Jacob Cline bergamot so are the hummingbirds

    Today I found a black moth with spikes along its abdomen. It had little yellow spots along the wing and a little bit of blue on the underside. Can anyone help me identify this?
