Fun Ceanothus Silkmoth Facts For Kids
Gallery
The Ceanothus silk moth (Hyalophora euryalus) is surely one of the most beautiful insects you will ever see.
It is a somewhat rare moth that primarily dwells in British Columbia but can also be found in other parts of Canada and the United States including south California, western Montana, Baja California Sur, and western Oregon.
The silkmoth is an astonishing sight from the moment it hatches out of its tiny egg. The hungry caterpillar will transform into many colors during its life cycle and so it begins the process within 15 minutes of being born.
The ceanothus silk moth may flaunt many shades as a caterpillar but nothing will prepare you for when it grows into a moth after it has hatched out of its cocoon.

Ceanothus Silkmoth Interesting Facts
What type of animal is a ceanothus silkmoth?
The ceanothus silkmoth is a species of insect. Its scientific name is Hyalophora euryalus. This colorful moth belongs to the family Saturniidae and genus Hyalophora.
What class of animal does a ceanothus silkmoth belong to?
The ceanothus silkmoth belongs to the Insecta class of animals.
How many ceanothus silkmoths are there in the world?
An accurate estimate of the number of ceanothus silkmoths is currently unavailable. This species is uncommon and these moths only live a week after they have emerged as adults. This makes it difficult to keep track of their population.
Where does a ceanothus silkmoth live?
Despite being one of the rarer insects, the Hyalophora euryalus has a rather wide range. It is primarily found in British Columbia, Canada but can also be found living in the United States in western Montana, south through to the west coasts of California and California Baja Sur, western Oregon, Canada, and south through to Washington.
What is a ceanothus silkmoth's habitat?
The Hyalophora euryalus can be found living in valleys, coastal areas, conifer forests, and chaparral.
Who do ceanothus silkmoths live with?
The ceanothus silkmoth is a solitary creature and it does not travel in groups or packs. Pairs may be spotted together during mating season.
How long does a ceanothus silkmoth live?
After silkmoths hatch from their eggs, they take a few months to turn into full-grown caterpillars. Once they have grown into their full size, they will spin a cocoon on a host plant and pupate inside it.
The cocoon takes about three to six weeks to close and from there, an adult ceanothus silkmoth will hatch. As adults, both the male and female butterflies survive only 7-10 days. Their sole purpose is to breed and begin the cycle.
How do they reproduce?
The female silk moth lays about 100 eggs per brood. To ensure every caterpillar gets enough food, the female moth glues her eggs either singly or in small clumps to different host plants.
The eggs take approximately 9-14 days to hatch revealing tiny caterpillars. Female adults also have to be extra cautious about which plant they are laying the eggs on because the baby caterpillar begins feeding right after they are born.
What is their conservation status?
The conservation status of Hyalophora euryalus is Not Evaluated by the IUCN due to their short lifecycle.
Ceanothus Silkmoth Fun Facts
What do ceanothus silkmoths look like?
The ceanothus silkmoth undergoes various color changes during its short lifetime. When it first hatches from its egg, the larva is no bigger than a penny and is covered in orange bristles. The larva quickly turns black within a mere 10-15 minutes.
As the caterpillar continues to feed, it enters the second instar. During this phase, it has an orange and yellow look. In the third instar, its color lightens to blue.
The bristles have pronounced yellow rings at the base. At the fourth instar, its color scheme further lightens to a pale sky blue. At the final instar, it flaunts an olive green shade.
When the Hyalophora euryalus finally emerges from its cocoon, it has reddish-brown wings with purple and pink bands around the edges. Its wingtips have eyespots. The hindwings also have bright white marks that resemble a pointy comma. The body is bulbous with orange and white stripes. Attached to its head are two antennae that are comb-like.
How cute are they?
The Hyalophora euryalus is a fascinating and beautiful creature. This colorful insect changes its hues many times during its time as a caterpillar. From orange to green and yellow to olive, the tiny caterpillar sports some of the most vivid and vibrant colors. Its many-hued bristles and spikes almost make it look like a firework.
How do they communicate?
The Hyalophora euryalus does not exactly send messages via wing flaps or sounds as you would expect. In fact, they rarely communicate with one another. The female Hyalophora euryalus communicates during mating season by emitting pheromones, a sort of chemical that helps the male moths to track down their location.
How big is a ceanothus silkmoth?
The Hyalophora euryalus is quite large in size. They have a length of 4 in (10.2 cm) on average. They are bigger than a peppered moth which is 1.6-2.4 in (4-6 cm).
How fast can a ceanothus silkmoth fly?
The female silkmoth avoids flying as its primary purpose is to mate and procreate. The male of this species flies up to 20 mi (32.2 km) in pursuit of the female.
They have rather large wings with a wingspan of 5 in (12.7 cm), helping them to zigzag through the wind and rain. The males use their antennae to track down the scent and will fly around until they find their mating partner.
How much does a ceanothus silkmoth weigh?
An accurate estimate of the weight of a Hyalophora euryalus is unavailable. As far as butterflies go, they are rather large and they could weigh on the heavier side.
What are the male and female names of the species?
No specific name has been allotted to the male and female adult Hyalophora euryalus. They are simply referred to as a male ceanothus silkmoth and a female ceanothus silkmoth.
What would you call a baby ceanothus silkmoth?
A baby ceanothus silkmoth is born as a caterpillar before they build a cocoon and emerge as a butterfly, so they are simply referred to as caterpillars during this phase of their life.
What do they eat?
Caterpillars are voracious eaters. This herbivore feeds on a variety of trees such as birch, manzanita, alder, buckbrush, willow, gooseberry, mantle, and mountain mahogany.
These trees also happen to be their host plants. Although the larvae feed on a wide range of plants and trees, their favorite is the California lilac (ceanothus). Unlike other moths, adult ceanothus silkmoths do not eat.
Are they dangerous?
The Hyalophora euryalus is not harmful unlike most other caterpillars with bristles. These moths also cannot bite. They are the ones who have to seek protection from predators.
Would they make a good pet?
Also, their life purpose is to breed so it is best they are allowed to live freely in the wild.
Did you know...
It is not uncommon for caterpillars to die inside their cocoon. If the cocoon bends and stays bent for a prolonged period, it means the animal inside is dead.
Some other fun moths are the gold moth, comet moth, and fairy moth.
The ceanothus silkmoth does not feed after it hatches from its cocoon. In fact, they are born without mouthparts. This is so that they don't have to go in search of food during their short life. They can only focus on breeding.
How long does it take a ceanothus silkmoth to come out of its cocoon?
The Hyalophora euryalus takes approximately three to six weeks to come out of its cocoon. The pupa also enters into the resting phase during the winter to avoid the harsh weather conditions outside.
What's the difference between a chrysalis and a cocoon?
Both the chrysalis and cocoon are the inactive immature form of an insect. This is the stage where the transformation of the insect from larva to adult begins. They do share one major difference. Only butterflies can make a chrysalis while cocoons are specific to moths.
Cocoons are silk casings spun by moths around themselves. They molt inside it. Butterflies, however, molt into a chrysalis.
