What Does The Harnessed Tiger Moth Look Like?
Harnessed tiger moth is one of the moths that looks quite similar to a butterfly. This is due to the bright and flashy colors in their bodies.
You can spot these moths flying around from spring to late autumn.
Similar to the others in the family, the harnessed tiger moth caterpillars have a grayish-black body covered with fuzzy bristles.
However, these bristle-like hair are yellow-colored. Also, you will notice a thin orange strip on its head.
The caterpillars actively consume herbaceous plants like dandelions, corn, etc. Adding to that, these insects are nocturnal in nature and are easily attracted by light sources.

Harnessed Tiger Moth Size – How Big Does The Harnessed Tiger Moth Get?
Harnessed tiger moths can get big, and an average healthy adult tiger moth can range from 1.18 to 1.65 inches in length.
The wingspan can be around 1.2-1.6 inches. When they spread those wings, the actual bright colors come into display.
You will notice that their abdomen is black with a red colored side. The hindwings have black patches, and the forewings display triangular patterns separated by tan lines.
This bright display of color is an excellent example of aposematic coloration. These colors serve as a signal to different predators that the moths have a foul taste.
Harnessed Tiger Moth Lifespan – How Long Does A Harnessed Tiger Moth Live?
Like the others in the moth family, harnessed tiger moth adults don’t survive for long. A healthy individual can live up to 5-10 days.
Soon after emerging from the pupae, they start mating. Both the male and female tiger moths die shortly after mating and laying eggs.
In some cases, these insects can die much earlier due to attack by predators like bats and birds.
You must note that the lifespan of an adult somewhat depends on the food they consume during the larval stage as caterpillars.

Harnessed Tiger Moth Life Cycle
Like butterflies, harnessed tiger moths also undergo the complete process of metamorphosis. The entire cycle has four stages: Eggs, Larvae, Pupae, and adults.
Mating & Egg Laying
The process starts with the mating of male and female moths. You must note that the eggs are fertilized inside the female body during mating.
After mating, these females carry the fertilized eggs in their bodies to lay them in a secure and warm spot. They ensure that the area is near a variety of host plants that the larvae feed on.
The females die soon after laying the eggs.
Caterpillar
It takes around ten days for the harnessed tiger moth caterpillars to hatch from the eggs. If the weather gets extreme, the time frame can differ.
After hatching, the caterpillars go on an all-out eating fest. They start by consuming the eggshell from which they emerged. This may sound weird, but these eggshells provide vital vitamins and proteins.
Once that is out, they shift to a nearby host plant and start consuming plant matter. These caterpillars must eat enough to be able to start pupating.
Tiger moths caterpillars can consume food that is more than 2,000 times their body weight.
Pupation
Once they have acquired enough nutrition to start pupating, they leave the host tree. The main focus now is to find a secure spot to start pupating.
The region must be away from potential predators like bats and birds. They barely select open areas to pupate as it makes them vulnerable to bird attacks.
Adults
Within three weeks, healthy adults come out of the pupa. The time period can be lengthier as it is hard for the delicate moths to break past the pupal cover.
Where Is Harnessed Tiger Moth Found & Their Range?
They are found in various parts of North America, across the US, Canada, and Mexico.
In the US, you can easily spot these insects in different states like: Alabama, Arkansas, Florida, Georgia, Michigan, Missouri, Nebraska, New Jersey, New York, Ohio, South Dakota, Texas, Vermont, and many more.
They prefer to be in areas filled with plenty of food sources.
Spots with abundant herbaceous plants like plantains, clover, corn, and dandelion can be great for searching for these insects.
They also prefer to live in an area that is well-protected from predators like bats.
What Do Harnessed Tiger Moths Eat?
Harnessed tiger moths adults don’t feed much as they live for shorter and spend most of the time mating. In rare cases, you spot them sucking nectar.
The caterpillars are active eaters. They love to consume herbaceous plants, different types of grasses, scrubs, and more.
These larvae value nutrition a lot. In fact, they consume the eggshells of the eggs from which they emerged to get the necessary proteins.
Are Harnessed Tiger Moths Poisonous?
Harnessed tiger moths are not poisonous. However, the adults secrete a liquid to ward off predators. This fluid can be harmful to humans.
It can trigger allergic reactions in the body. Also, the furry body of the caterpillar can cause rashes and irritation if touched with bare hands.
Do Harnessed Tiger Moth Bite?
Harnessed tiger moths do not bite and don’t have a stinger as well. The only concerning factor is the tiger moth fluids that it releases.
These fluids can be harmful to humans. Adding to that, the liquid smells quite bad.
Avoid touching the moths and caterpillars without wearing safety equipment like gloves to keep injuries and allergies at bay.
How To Attract Harnessed Tiger Moth?
Harnessed tiger moths are easy to attract if you know the right hacks. This section will discuss a few productive ways to attract these insects.
Leave the porch lights on
Harnessed tiger moths are nocturnal and are attracted to light sources. It is easy for them to spot a lone light source from a distance.
Keeping your porch lights on during the night will lure these insects toward the source and reach your yard.
Have plants that the caterpillars like
As mentioned in the sections above, the females prefer to lay eggs in areas with abundant food sources. You can have a range of herbaceous plants and trees that will instantly attract female moths to your garden.
Here is a list of plants you should plant:
- Red maple
- Paper birch
- persimmon
- black walnut
- American chestnut

If you want around, it is best to keep your garden free from these potential predators. A safe environment is ideal for the moths to lay eggs.
Harnessed Tiger Moth Spiritual Meaning
There are many spiritual meanings attached to tiger moths. Different types of tiger moths hold different gravity in various cultures worldwide.
For example, white-colored moths are considered a sign of peace and innocence. This is because white is often considered the color of peace.
However, particular spiritual meanings attached to tiger moths hold true for all the different species in the family. Mentioned are two of the most common spiritual meanings:
Embracing the light
Since tiger moths are attracted to light sources, it is common to spot them swarming or flying toward a glowing object.
This practice is used as an example to keep moving from darkness to light.
Thus, spotting a tiger moth is an indication that the person must leave the dark and start embracing the light in their soul.
Being rational
The same practice of the moth flying toward light is taken as a warning sign in some cultures.
It teaches that no matter how enticing the glow is, being too close to the fire will burn you.
Therefore should not be easily lured by charming deals or things and think rationally before making a decision.

Harnessed tiger moths might be beautiful to look at, but these insects are not the best ones to have around.
They emit a foul-smelling liquid that can cause health problems; therefore, these insects must be kept away from your house and yards.
Here are a few tips to get rid of harnessed tiger moths from your home and garden:
Keep the porch lights off.
As we stated in one of the sections above, lights are one of the attractive things for these insects. As soon as they spot a glowing object, they start flying toward it.
This is why you must limit porch light usage to a bare minimum. Also, remember to close the windows and doors during the nighttime.
These insects will take every opportunity to enter a well-lit home.
Vinegar: The best natural repellent
Instead of using pesticides to drive harnessed tiger moth caterpillars out, use vinegar. Yes, you read it right. Caterpillars don’t like the smell of vinegar.
They usually do not dwell around an area that smells the same. Sprinkle it on spots where these caterpillars gather and wait for the magic to happen.
Use pepper-garlic mixture
Another effective way to deal with the caterpillars is using a pepper and garlic mixture. Create a mixture of pepper and garlic, and add it to a bottle of water.
Spray this solution directly on the caterpillars. This natural solution will kill the caterpillars slowly.
