Hooktip moths are a fascinating group of insects belonging to the order Lepidoptera, which includes all the moths and butterflies. Known for their unique wing shape and vibrant patterns, these moths have captured the attention of scientists and nature enthusiasts alike.

In the world of Lepidoptera, hooktip moths stand out due to their distinct wingtips. These unusual appendages curve outward and form a hook-like shape at their apex. The diversity within the family allows for a wonderful array of colors and patterns, making them interesting subjects for those studying insect morphology and behaviors.

While some hooktip moth species are appreciated for their aesthetic appeal, others might be considered pests due to their feeding habits. Despite this, these moths continue to be an essential part of the ecosystem and offer valuable insights into the incredible diversity of insects that inhabit our planet.

Hooktip Moths and Their Family

Drepanidae Family

The Drepanidae family contains approximately 660 species of hooktip moths found worldwide1. These medium-sized moths, known for their distinctive wing shape, are part of the Lepidoptera order2.

Characteristics of Drepanidae moths include:

  • Wingspan: 1″ – 1 ½”
  • Uniquely-formed hearing organs
  • Hooked wing tips (not present in all species)

Subfamilies: Thyatirinae, Drepaninae

Thyatirinae: This subfamily is known for its striking patterns and wing shapes. It comprises mostly nocturnal moths.

Drepaninae: Featuring uniquely curved front wings, this subfamily includes species like the Arched Hook-tip Moth, prevalent in various regions except the Great Plains and Gulf Coast1.

False Owlet Moths

False Owlet Moths, another important group within the Drepanidae family, stand out for their interesting patterns and mimicry of other species.

Comparison of Subfamilies

Subfamily Notable Features
Thyatirinae Nocturnal, striking patterns
Drepaninae Curved front wings
False Owlet Interesting patterns, mimicry

Physical Characteristics

Wingspan and Appearance

  • Hooktip moths have a unique sickle-shaped wing feature.
  • Their wingspan typically ranges from 20 to 40mm.

Examples of hooks on their wings:

  • Family Drepanidae
  • Species Drepana arcuata

Forewings and Hindwings


  • Larger than hindwings
  • Distinctive hooked shape


  • Smaller than forewings
  • Often have similar patterns to the forewings

Mouthparts and Proboscis

  • Hooktip moths possess a proboscis for feeding.
  • The proboscis is coiled when not in use.
  • They have a well-developed sense of taste with their mouthparts.
Feature Hooktip Moth Other Moths
Wingspan 20-40mm Varies by species
Wing shape Sickle-shaped hooks on wing tips Varies by species
Proboscis Coiled when not in use, used for feeding Varies by species (may or may not have)
Mouthparts Well-developed sense of taste Varies by species

Life Cycle and Behavior

Larvae and Caterpillars

Hooktip moths begin their lives as larvae, also known as caterpillars. These larvae hatch from eggs and start feeding on their host plants.

Caterpillars of various species can vary greatly in appearance but typically have distinct head capsules, segmented bodies, and several pairs of legs.

Cocoons and Pupae

After a few weeks, the larvae form cocoons, which are protective structures made of silk. Inside the cocoon, the larva undergoes metamorphosis and turns into a pupa.

Pupae tend to have tightly wrapped wings and reduced legs. This stage is vital for the moth’s development into an adult.

Masked Birch Caterpillar

The Masked Birch Caterpillar is a unique example of a Hooktip moth caterpillar. It feeds primarily on birch trees. Some interesting features include:

  • Distinct white & black patterning
  • Party-mask-like pattern on the head capsule


Frass is insect waste that is produced by caterpillars during their feeding process. For Hooktip moth caterpillars, frass can be observed near feeding sites on leaves or branches.

Distribution and Habitat

Range in North America and Europe

Hooktip Moths are found in a variety of habitats across North America and Europe. In North America, their range extends from the Yukon and Alaska down to Newfoundland. In Europe, they are found throughout the United Kingdom, including England, Wales, Scotland, and Ireland.

Key Habitats: Oak Hook-tip and Other Species

Different Hooktip Moth species have specific habitat preferences. For instance, the Oak Hook-tip Moth is commonly found in:

  • Alnus (Alder) forests
  • Betula (Birch) woodlands

Below is a comparison table of key habitats between Oak Hook-tip Moths and other Hooktip Moth species:

Species Habitat
Oak Hook-tip Alder forests, Birch woodlands
Other Species Various habitats, including coniferous forests

The distribution of Hooktip Moths is influenced by factors like availability of food plants and suitable habitat conditions. In the UK, they are considered a priority for conservation efforts under the UK BAP (UK Biodiversity Action Plan).

Identifying Hooktip Moths

Guide to Similar Species

Hooktip moths belong to the family Drepanidae, characterized by their distinctive hooked wingtips. Here are some features to aid in identification:

  • Curved antennae
  • Slender body
  • Wings with a hooked apex

There are other similar species with hooked wingtips, such as the oak hook-tip. This moth belongs to the same family but can be differentiated by its distinct markings and colors.

Drepana Arcuata and Other Examples

Drepana arcuata, commonly known as the orange hooktip, is a great example of a hooktip moth. Some key characteristics include:

  • Orange to brown coloration
  • Forewings marked with an arc-shaped white band
  • Hooked wingtips

Other examples of hooktip moths that share some similarities with Drepana arcuata are the common hook-tip (Drepana falcataria) and the scarlet hook-tip (Drepana curvatula). These moths have similar wing shapes but differ in color patterns and wing markings.

In summary, identifying hooktip moths can be achieved by focusing on their unique features such as hooked wingtips and distinctive markings. Some examples within this family include Drepana arcuata, the oak hook-tip, and other similarly shaped species.

Over the years, our website, whatsthatbug.com has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Rose Hooktip


rosewing hooktip moth
Good evening Mr. Bugman,
I just discovered your site today, and as an inveterate 1. namer, 2. shutterbug (didn’t find that one on your site) and especially 3. macro fiend I was more than delighted! I’ve already ID’d several ‘bugs’ that had been bugging me. Thank you so much. I’ve attached 5 photos – 4 I know, and one I’d like to confirm. I live in Orange County, VIRGINIA – the north central piedmont of the state. All photos have been taken within a 4 mile radius of Orange, VA (county seat). If you don’t object, I’ll send others of insects you don’t appear to have – and maybe a few that I need help with. I just don’t want to overdo it in my enthusiasm for your site. What a great service, and I’ll add that no insects are harmed in the photographic process. They are either in the wild or occasionally found deceased, although no deceased ones in this group. 2. Rosewing hooktip, (Oreta rosea) – beautiful moth, found on the ceiling of my front porch in Orange (May 2005). Taken with a flash, so the colors are a tad exaggerated. Thanks again for the wonderful site!
Best regards,
Orange, VA

Hi Lynne,
We are overwhelmed by all the images you sent in and have chosen to post the Rose Hooktip first as this is a new species for our site. In the future, please send only one image or one species per letter. It makes our lives so much easier. Thanks so much for expressing your enthusiasm.

Good morning Daniel, I apologize for loading my first email with photos, and will in future keep to one species/photo per. I’m glad you found some of my snaps useful and that I could contribute a new species for the site. Oh, and since it might be of interest, all of my pictures have been taken using a digital Nikon 880 Coolpix (pre-October 2005) or a digital Nikon 4800 Coolpix. Cheers,

Letter 2 – Rose Hooktip Moth


Whats This Bug
I live in southeastern Ohio. Could you tell me what this beautiful moth / butterfly is? I found it in the shade next to the door of my house. At first I thought it was a leaf, then I noticed it was actually an insect. I am very curious. Thank you,

Hi Jennifer,
This little beauty is a Rose Hooktip Moth, Oreta rosea. It is the only member of its genus in North America. BugGuide has some excellent examples of the color variations of this species.

Letter 3 – The Scribe


Long shot… cute squiggly brown moth
Location: Norther Colorado mountains
July 19, 2011 9:40 am
Yea, I know noctuid moths (which I assume this guy is) can be tough. A long time moth enthusiast (all bugs actually) I leave the light on for them and love seeing who came to visit over night. I no longer kill and collect them, but I do regularly refer back to my 4-H collection.
This guy visited a couple days ago (July 11th, give or take. I can’t seem to pin him down (no pun intended). For some reason, I decided to focus my attention to identifying it this morning, 3 hours online, no avail. Any thoughts?
Norther Colorado foothills/mountains, 15 miles by crow west of Fort Collins, 40 miles by crow south of Wyoming. 8100 feet.
Signature: Matt B

I’d also like to add… if there is a need, I’d be happy to volunteer some time to help with ID requests. Especially those that are semi local to me, as I am pretty familiar with northern CO species, having collected hundreds of different species during my 10 year 4-H entomology tenure…
Feel free to fwd anything that comes in. I love the challenge  🙂
Love your website!

Unknown Moth

Hi Matt,
Your are sure right about some moth identifications being extremely difficult.  We are posting your photo and indicating that it is unidentified.  We hope our readership is able to provide an identification.  We greatly appreciate your identification offer.  You might want to start to peruse our unidentified tag to see if you can provide comments to any of those postings.

Identification provided thanks to littlechkn’s comment
Seems this may be The Scribe or Lettered Habrosyne, and the images on BugGuide looks correct.  It is in the family Drepanidae, the Hooktip Moths and False Owlet Moths.
