Do Plume Moths Bite? Unraveling the Mystery

folder_openInsecta, Lepidoptera
comment24 Comments

Plume moths are unique insects known for their T-shaped silhouette and muted colors. Resting with their wings tightly rolled, these delicate moths have a slim body and long, fragile legs. When it comes to the question of whether plume moths bite, it’s important to clarify that adult moths and butterflies do not sting or bite.

However, when discussing the potential for bites or stings, we should consider their larval stage. Plume moth larvae, just like other moth and butterfly caterpillars, can cause skin irritations or reactions in some cases. These reactions are collectively known as “Lepidopterism” and are specifically caused by contact with larvae or caterpillars, not the adult form of the insects.

Do Plume Moths Bite?

Biting vs Non-Biting Species

Plume Moths are delicate-looking insects with T-shaped silhouettes and muted shades of tan and brown 〰️. As moths, they belong to the Lepidoptera order. These moths have a non-biting proboscis, which they use to feed on flower nectar.

In comparison, biting insects like ants have mandibles for biting and stinging 〰️.

Moths vs Ants:

Insect Biting Feeding Mechanism
Moth No Proboscis
Ant Yes Mandibles

Allergic Reactions and Skin Irritations

Although Plume Moths don’t bite, some people might experience skin irritations or allergic reactions from contact with other moth species in rare cases. This condition, known as Lepidopterism, could result in:

  • Redness
  • Itching
  • Swelling

However, Plume Moths aren’t known to cause such reactions.

Characteristics of Plume Moths

Morphology and Wingspan

Plume moths are recognized by their unique morphology and muted shades of tan and brown. Their slim, delicate appearance and long, thin abdomens contrast with their extremely long, fragile legs. These moths possess a wingspan ranging from 10 to 50 millimeters.

Features of plume moths include:

  • T-shaped silhouette
  • Muted shades of tan and brown
  • Slim and delicate-looking body
  • Long, thin abdomen
  • Extremely long, fragile legs

Moths and Butterflies Comparison

It’s easy to distinguish plume moths from butterflies through their antennae. Butterflies have club-shaped antennae with a long shaft and a bulb at the end, while moth antennae are feathery or saw-edged.

Feature Butterflies Moths
Antennae Club-shaped Feathery or saw-edged
Active during Daytime Nighttime (mostly)

Family Pterophoridae and Genus

Plume moths belong to the family Pterophoridae, which has around 160 species in North America. The distinguishing characteristic of this family is their deeply divided wings, which form fringed lobes. Hind wings typically have three lobes, while forewings have two.

Pterophoridae characteristics:

  • Deeply divided wings with fringed lobes
  • Hind wings with three lobes
  • Forewings with two lobes

Habitat and Diet

Geographic Distribution

Plume moths are found throughout North America and have a distinct T-shaped silhouette. They inhabit various ecosystems, depending on the availability of food sources.

Food Sources

The diet of plume moths varies based on their life stage:

  • Larvae: As caterpillars, plume moths feed on plants such as snapdragons and bindweed.
  • Adults: Plume moths primarily consume nectar from flowers while indirectly collecting and transferring pollen.

Comparison of food sources:

Life Stage Food Sources
Larvae Snapdragons, bindweed
Adults Nectar from various flowers

Ecosystem Roles

Plume moths play crucial roles in their ecosystems:

  • Pollination: Adult plume moths are important for moth pollination, particularly for nocturnal flowers.
  • Food source: As caterpillars, they provide sustenance for predators in the ecosystem.

Key ecosystem roles:

  • Pollination
  • Providing food for predators

Natural Enemies and Controlling Infestations

Predators and Biological Control

Some natural enemies of plume moths include mice, birds, and predatory insects. These predators help in controlling infestations by feeding on plume moth eggs and larvae. Additionally, some specialized wasps and fly species attack plume moths as parasitoids.

Biological control can be an effective, eco-friendly method for controlling plume moth infestations. Some benefits of using biological controls include:

  • Reducing the need for chemical pesticides
  • Minimizing potential harm to non-target species
  • Promoting long-term pest suppression

Home and Garden Management

To manage plume moth infestations in your home and garden, consider the following steps:

  • Inspect regularly: Check plants for signs of infestation, such as eggs or larvae.
  • Hand-picking: Remove pests by hand when possible, placing them in a container of water to dispose of them.
  • Natural repellents: Use non-toxic or organic repellents that deter plume moths without harming beneficial insects.
  • Moth-zapper: Install a moth-zapper in your garden to attract and kill adult moths.

Here’s a comparison table to help you decide which method best suits your needs:

Method Pros Cons
Hand-picking No chemicals, eco-friendly Time-consuming, not practical for large infestations
Natural repellents Low environmental impact, generally safe May require frequent reapplication, effectiveness may vary
Moth-zapper Efficient, low maintenance Can also kill beneficial insects, may not be as effective in winter

Remember to choose a control method that aligns with your goals, and consider using multiple strategies for the best results.

Impact on Humans and Materials

Moths vs. Fabrics and Pantry Items

Moths typically do not bite humans, but they can cause damage to certain materials in your home. Some moths, like clothes moths, target natural fibers such as wool and cotton in clothing and carpets. Pantry moths, on the other hand, infest grains, fruits, and other stored food items.

Fabrics at risk:

  • Wool
  • Cotton

Pantry items at risk:

  • Grains
  • Fruits

Dealing with Infestations in the Home

It is essential to address moth infestations promptly to minimize damage to your belongings and to ensure a healthy living environment. Some people may experience allergies to moths, so it is important to take necessary precautions.

Steps to deal with moth infestations:

  1. Identify the type of moth (clothes moths or pantry moths).
  2. Inspect and clean affected areas.
  3. Use a vacuum cleaner to remove moth eggs, larva, and adult moths.
  4. Wash and sanitize clothing, carpets, and pantry items.
  5. Seal grains and other pantry items in airtight containers.
  6. Check for moth activity regularly.
Clothes Moths Pantry Moths
Target natural fibers (wool, cotton) Target stored food items (grains, fruits)
Damage clothing and carpets Contaminate pantry items
Can cause allergic reactions May not cause allergic reactions

In conclusion, plume moths do not bite, but other types of moths can cause damage to fabrics and pantry items in your home. By following these steps, you can effectively deal with moth infestations and protect your belongings.

I found this on the window of a restaurant. Never seen anything quite like it. It was moving only slightly, and a while later I looked again and it was gone, I’d like to know where it keeps its wings…
Got top and bottom pictures by virtue of the glass. I’d say it was about an inch square.

Mosquito-Moth looking insect?
Location: western New York state
June 3, 2011 8:50 am
Hi, I found this insect taking a break on the outside of our storm door this morning. It appears to have a mosquito body with weird moth-like wings and a curved up tail…I’ve never seen anything like this. Oh, I forgot to get a picture of this, but the legs all came straight down from the thorax to a central grouping, then went outwards. Kinda made it look like the insect had a deeply keeled chest.
I can generally guess the Order of an insect, and often narrow it down to Family when attempting to look one up – but this one has me stumped.
It’s a chilly morning today (even with it being June!), below 60F right now. I think it was trying to warm up in the sun – certainly didn’t mind me taking photos or jostling the door.
Anyways, I’d love to know what genus and/or species this critter is. Thanks in advance!

Hi Kimberly,
We get countless requests to identify Plume Moths in the family Pterophoridae, and your creature is a member of that family.  Often those identification requests include the graphic description “T Bug” and most members of this family are characterized by their unusual wing formation which causes the insect to resemble the letter T.  Trying to get your individual identified to the genus or species level might be difficult.  BugGuide is a good place to begin that task.  Since we will be out of the office for a week in mid June, we are preparing your letter to go live to our site on June 14.

Letter 13 – Many Plumed Moth from Australia


The most beautiful moth ever?
Sun, Oct 19, 2008 at 10:47 PM
Hi guys,
I just photographed this tiny diaphenous moth on the mudguard of my car and had to share it with you. I’ve sent it to you in a large picture size as the specks make it hard to see detail when it is downsized. The background is the green metallic paint of my car, the moth is only about 1cm wingtip to wingtip. I am blown away by how beautiful it is and so delicate, it is one of the most beautiful moths I have ever seen. Hopefully someone knows what it is.

Hi Trevor,
WE are quite certain this is a Many-Plume Moth in the family Orneodidae, but we haven’t the time to research an exact species. With our current internet problems due to a weak Time Warner signal that the cable company is having problems correcting, we cannot do any further research at the moment. Our very old edition of An Introduction to Entomology by John Henry Comstock states: “These insects resemble the Plume-Moths in having the wings fissured; but her the fissuring is carried to a much greater extent than in that family, each wing being divided into six plumes.” Perhaps this information will help with an exact identification.

Often found hibernating.  Gardens and woodland where foodplant (Honeysuckle) found.  Each wing is separated into 6 ‘plumes’, making the English name for this unusual little moth rather inaccurate!”

This is a gorgeous image of a Many Plumed Moth in the genus
Alucita.  According to BugGuide:  “larvae are associated with snowberry (Symphoricarpos spp.; Caprifoliaceae) in the north, and honeysuckle (Lonicera spp.) in California” so we are deducing you must have those plants nearby to account for the large numbers of adult moths.

Thanks Daniel

Dear Cheryl,
Many folks who write to us wanting a Plume Moth in the family Pterophoridae identified frequently refer to them as “T-Bugs“.  According to the Missouri Department of Conservation:  “Plume moths are instantly recognizable by their T-shaped silhouette and muted shades of tan and brown. At rest, the moths hold their wings tightly rolled, but when they are spread, the deeply cleft slits in the wing margins that create the feathery plumes are visible. These moths are slim and delicate-looking, with a long, thin abdomen and extremely long, fragile legs. Their flight is weak and fluttery. It can be hard to distinguish among the many species of plume moths.”

So I thought I might ask you again now when the bugs are mostly hiding from the cold. I hope that you are no longer too busy to check it out for me. I still can’t find it in a book anywhere. The wings are four and quite narrow. The wingspan is about an inch and a half. It appears to have only four legs. There is a little furry spot above its eyes.

I took this photo a couple of years ago, and I still don’t know what it is. The bug is on my kitchen wind (you can see the blinds in the background, which indicate the bug was about 4 inches long.

Hi Terry,
This is a Plume Moth in the family Pterophoridae, which according to BugGuide, is:  “A distinctive family of moths, but difficult to identify to genus or species.”  Many people write to us referring to Plume Moths at T-Bugs.  In our opinion, your estimation of the size of this Plume Moth being four inches is quite an exaggeration as they rarely exceed two inches in wingspan.

Hi Timothy,
The best we can do is to provide a family identification.  This is a Plume Moth in the family Pterophoridae, and it is often very difficult to identify individuals to the genus or species level.  See BugGuide for additional information on the Plume Moths.

Found on car door in garage. What kind of bug is it? Can’t find anything that looks similar to it. Sent the little guy on its way after snapping the pic.

We believe this is one of the Plume Moths in the family Pterophoridae, though the wings appear to be at a 90 degree angle to one another and we are used to seeing them at a straight 180 degree angle, which when combined with the body gives the resemblance to the letter T, causing people to call them T-Bugs.

    Saw one on a door in Salmon Arm BC. the building was the Prestige Inn on the waterfront.Not able to capture an image.

  • LOL! For a few seconds, when I first looked at the picture, I thought that the door lock was a beer or soda can seen from above, than I thought it was a giant plume moth.

  • A question rather than a comment guys. Do you know how many plume moths are coloured rather than just white or grey as most seem to be?

  • I have a few of these hanging out around the porchlight each night, lately — most just over an inch, but occasionally smaller. I also have a lot of Morning Glory. In any case, I’m wondering if you know about their eggs — I’m in Berkeley, California — might I start seeing them now? What do they look like? And what are they likely to be on? The Morning Glory????
    — oh and — you say “late May to September.” Would that include California? Thank you!

  • Just found one of these on the ceiling of my apartment in Seattle. Its an inoffensive insect, sat there for a day, moved about 6 feet in the night and was in a different spot on the ceiling in the morning.

    No idea what it was, and Google wasn’t helping because I had no idea how to describe it. So I got a broom and gently tapped it hoping it’d climb aboard for a closer look. To my surprise it started flying. Once I realized it was a moth, I typed “airplane moth” into Google and found it. Cool bug, lived in WA my entire life, never seen one before.

  • Hi Dana,
    They are quite wonderful Plume Moths- the first one I ever saw one was in Montana 🙂 where we lived in a forest area…
