What Does A Scarlet Tiger Moth Look Like?
Scarlet tiger moths belong to the Arctiidae family in the Lepidoptera order. They are a type of tiger moth, as the name suggests.
A scarlet tiger moth can be identified by the bright colors on its body.
The forewings are black with yellow spots. But the real attraction is the hindwings; these are bright orange in color with black eyespots that look very much like bug eyes.
Little do observers know that these eyespots have a specific purpose – they are a tool to signal the predators that they are not appealing prey.
Moreover, these spots make them appear bigger.
The colors of the wings also have the same function – while it may look beautiful to us, these bright colors mean something entirely different to predators in the wild.
They signify danger or a hard to eat prey. This is an excellent example of aposematic coloration.
On rare occasions, you might spot a scarlet tiger moth with yellow hindwings as well.
Scarlet Tiger Moth Size – How Big Does Scarlet Tiger Moth Get?
Scarlet Tigers fall in the category of large moths.
They can have a wingspan of 1.88 – 2.2 inches. The moth caterpillars are black to grayish in color with white and yellow dots on the body.
An average healthy caterpillar can grow up to 1.6 inches long.
You must note that the growth significantly depends on the quantity of food that they consume during the larval stage.
Scarlet Tiger Moth Lifespan – How Long Do Scarlet Tiger Moths Live?
Adult moths don’t live for long. A healthy scarlet tiger moth can survive for a few weeks and spend most of their lives caterpillars.
Another interesting thing to note here is that these insects can spend around four months inside their cocoon before emerging as adults.
The time can vary according to the size of the moth.
In the wild, there is always a danger of them being hunted down by potential tiger moth predators like bats, small mammals, reptiles and birds.
Scarlet Tiger Moth Life Cycle
Mating
Scarlet tiger moths adults emerge in the months of June and July. Soon after emerging, these adults mate.
During mating, the eggs get fertilized inside the female body.
Later the females carry these eggs to good food plants like common nettle, comfrey, and green alkanet and lay them there.
Egg Hatching
Within seven days, the eggs hatch.
As soon as the caterpillar comes out, they directly start eating the shells of the eggs from which it hatched.
These eggshells are a rich source of protein and vitamins.
Once that is done, they start feeding on the host plant (we mention which ones in a little while).
From time to time, they keep shifting from one host plant to the other to get sufficient food out of them.
These larvae can easily eat plant matter weighing 2,700 times their own body weight. It is crucial for them to eat properly to be able to grow into healthy tiger moths.
Once they have eaten enough, they leave the host tree and start searching for secure spots to start pupating.
It might take a while to find the right spot as they are extremely careful about avoiding predators at this stage.
Pupation & Becoming Adults
The moth remains in the cocoon for around four months. The time can be longer depending on the size and strength of the adult that emerges from the pupa.
As adults, they feed on nectar and are often seen around gardens with plenty of flowers.
Where Is Scarlet Tiger Moth Found & Their Range?
Scarlet tiger moths prefer to be in coastal habitats like fens, floodplains, wetlands, riverine habitats, and beaches.
You will also find them in open woodlands, gardens, and ditches.
They are found in different parts of the UK and Wales. A big population of these tiger moths is found in West and South England. There are some isolated populations in Kent.
While most of these beautiful moths live in the UK, there are a few populations in the rest of Europe as well, spreading upto Turkey.
In the US, they have been spotted in Jersey during the last 20 years.
You can find them roaming around during the daytime, basking in the sunlight, or resting on leaves. They are active during the night.
What Do Scarlet Tiger Moths Eat?
Scarlet tiger moth adults live longer than the other tiger moth species.
Unlike their relatives, they actively drink nectar from hibiscus, petunias, goldenrod flowers, and verbenas.
The scarlet tiger moth caterpillars eat a wide variety of herbaceous plants like common nettle, honeysuckle, rose, sallows, and common comfrey.
The caterpillar often shifts from one host plant to another to get strong enough to transition into the pupation process and later emerge as an active adult.
Are Scarlet Tiger Moths Poisonous?
Scarlet tigers are not poisonous, but it is not safe to touch these insects directly.
When the adult tiger moth feels threatened, they release a foul-smelling liquid that makes the predators sick and makes them look unappealing as prey.
This smelly fluid can trigger allergic reactions in the human body.
You must also note that various colors of tiger moths are a sign to the predators that hunting and eating will not be a wise choice.
Touching the caterpillars is also not advisable as the bristle-like hair in the body might pierce through the skin and cause rashes and irritation.
Do Scarlet Tiger Moths Bite?
Scarlet tiger moths do not bite or sting. These insects are not aggressive and quite delicate. But don’t be complacent around them.
As mentioned in the previous section, they emit a fluid that can cause allergic reactions in the human body. If you want to touch them, it is wise to wear safety gloves.
How To Attract Scarlet Tiger Moth?

- Honeysuckle
- Rose
- Sallows

- Willow
- Black walnut
- Paper birch
- Smooth sumac

- American chestnut and
- White oak
These trees/plants are excellent host plants for the caterpillars to grow. The females will prefer to lay eggs in spots filled with good feeding options for the larvae.
Use lights
Unlike other tiger moths, scarlet tiger moths are day-flying species. You can find them flying around the garden in the daytime, but they are also active at night.
Moreover, these insects are attracted to light sources in the dark. Keep the porch lights on to lure these insects to your yards or gardens.
You can also put a portable light in the middle of your garden to get better results.
Keep predators away
It is obvious that scarlet tiger moths won’t be around areas filled with potential predators; therefore, you must keep birds, lizards and small rodents away from the garden.
The females will only lay eggs in your garden if is free from all predatorial dangers.

How To Get Rid Of Scarlet Tiger Moth?
These brightly colored moths are great to look at, but that doesn’t mean they are equally good to touch or play with.
Children can especially get hurt by the foul-smelling liquid that they emit.
Keeping these moths away from your home is a wise choice to stay safe. Here are a few hacks to drive these insects away from your garden and home:
Use pheromone traps
A Pheromone trap attracts these insects to fall on a sticky surface where they get stuck. You can buy these traps from the nearest pet store.
Install them in areas where you notice frequent moth activity. Once they land on a sticky surface, you can throw the moth out and put it back in the same place.
Invite predators like birds
Birds love to eat caterpillars and scarlet tiger moths. Having them around your garden will not only remove the existing moths but also prevent them from coming back.
Sprinkle some bird feed in your garden regularly, and in no time, they will hunt down all the caterpillars and the moths.
Use natural remedies
Vinegar is an excellent natural repellent for woolly bears. Tiger moth caterpillars do not like the smell of vinegar as it is an excellent repellent.
Spray some drops of vinegar on plants where the caterpillars gather, and you won’t see them there after a few days.
A garlic, pepper, and water mixture are highly effective for killing tiger moth caterpillars.

If you google Creatonotos gangis there are moths with similar “Hair Pencil” glands that secrete pheremones to attract mates. https://en.wikipedia.org/wiki/Hair-pencil
Thanks for the correction and link.
No its not a hoax ! The X thing is an organ of the moth used either to scare away predators or for copulating purposes. I’ve seen it before personally !
Androconial organs: https://www.youtube.com/watch?v=QQlhGT2VMOQ
Thanks for the correction.
the tentacle things are part of the moth, they’re called coremata
I had to look the name up, but it’s definitely a scent organ called the coremata male moths have.
Spilosoma glatignyi?
Can you provide a link? It looks nothing like the images posted to Butterfly House.
