Physical Characteristics
Adult Moths
Adult Virginia Ctenucha moths (Ctenucha virginica) are medium-sized with a wingspan of around 22-23 mm. They have striking orange heads and metallic blue-black bodies. Their wings are dark and iridescent, making them resemble certain butterflies, like irises. However, they can be distinguished by their:
- Fast flight towards vegetation
- Darting under leaves to hide
Larvae Stage
Virginia Ctenucha moth caterpillars are quite different in appearance when compared to adults. Some key features include:
- Long, hair-like setae
- Bright coloration, often orange or yellow
- Dark markings on their bodies
Moths like Virginia Ctenucha undergo a complete metamorphosis, transforming from the larval stage to the adult stage.
Identification Features
Identifying Virginia Ctenucha moths can be made easier by examining a few key features such as:
- Orange head and collar
- Metallic blue-black body
- Larger size compared to the Yellow-Collared Scape Moth (Cisseps fulvicollis)
Here’s a comparison table of Virginia Ctenucha and Yellow-Collared Scape Moth:
| Feature | Virginia Ctenucha | Yellow-Collared Scape Moth |
|---|---|---|
| Head and collar color | Orange | Yellow |
| Body color | Metallic blue-black | More brownish |
| Size (wingspan) | 22-23 mm | Slightly smaller |
| Flight and hiding behavior | Faster, darts under leaves | Less agile |
When identifying moth species, it is important to consult reliable resources like Butterflies and Moths of North America for correct information.
Habitat and Range
Geographical Spread
The Virginia Ctenucha moth (Ctenucha virginica) can be found throughout a notable portion of Eastern North America. Its range stretches from the southern parts of Canada, such as Manitoba, to several states in the United States. You will discover them in areas like Georgia, Pennsylvania, Kansas, and as far north as Labrador.
Microhabitats
The Virginia Ctenucha moth prefers specific microhabitats in its range. These particular environments include:
- Fields
- Meadows
- Grasslands
- Open woodlands
These moths thrive in areas with a diverse array of plant life, which provides ample food sources and opportunities for them to lay their eggs. Their larvae feed on multiple grass and sedge species, which can commonly be found in the habitats mentioned above. So, when exploring fields, meadows, or grassy woodlands in Eastern North America, be on the lookout for these fascinating creatures that make their home among the diverse plant life.
Behavior and Habits
The Virginia Ctenucha moth is an interesting species with unique behaviors and habits. During the day, you can often spot these moths basking in the sun. They are diurnal, which means they are active during daylight hours rather than at night.
Their habits include feeding on a variety of plants. You might notice them on flowers such as the goldenrod, where they sip nectar using their long proboscis. These moths are also known for having two broods per year, leading to a more extended flight period throughout the warm months.
One fascinating aspect of the Virginia Ctenucha moth is its ability to overwinter. They do so as caterpillars that can tolerate the cold temperatures. During this time, their growth slows down, conserving energy to survive the winter months. When warmer weather returns, they continue to grow and eventually form cocoons before transforming into adult moths.
In summary, some key features of the Virginia Ctenucha moth’s behavior and habits are:
- Being active during daytime
- Feeding on various plants and flowers
- Having two broods per year
- Overwintering as caterpillars
Food Habits
The Virginia ctenucha moth, a beautiful and intriguing species, has some interesting food habits that you should know about. In this section, we’ll discuss what these moths typically consume and how they obtain their sustenance.
As a caterpillar, the Virginia ctenucha feeds on various types of plants. Some examples of their preferred food sources include:
- Grasses: They consume the leaves and stems of various grasses.
- Sedges: These plants are also a favorite of the caterpillars.
- Goldenrod: The larvae enjoy munching on the foliage of goldenrod plants.
When the Virginia ctenucha matures into a moth, its food habits shift. As an adult, it primarily seeks nectar from flowers, with a particular preference for flowering plants that provide plenty of this sweet substance. To satisfy their hunger, they visit a variety of flowers, sipping the nectar through their proboscis, a long and flexible mouthpart.
It’s important to remember that the food habits of Virginia ctenucha moths play an essential role in their ecosystem. They help pollinate the flowers they visit, contributing to the health and diversity of the plant life around them.
By understanding the Virginia ctenucha moth’s food habits, you can appreciate the valuable part they play in their environment and perhaps even support them in your own garden by planting flowers that provide an abundant source of nectar.
Classification
Taxonomic Classification
The Virginia Ctenucha Moth (Ctenucha virginica) is a fascinating insect belonging to the kingdom Animalia, phylum Arthropoda, class Insecta, and order Lepidoptera. The moth is in the family Erebidae, and within the subfamily Arctiinae1. The family Erebidae is a prominent moth family, while the Arctiidae family is now considered a part of it2.
Moths vs Butterflies
It might be confusing for some people to distinguish between moths and butterflies, but there are a few differences that can help you tell them apart:
- Moths tend to have feathery antennae, while butterfly antennae are thin and club-shaped.
- Butterflies are usually active during the day, while moths are typically active during the night.
- Moths tend to have more subdued colors and patterns, whereas butterflies are more vibrant3.
Photography and Observation
Finding and photographing Virginia Ctenucha Moths can be a fun and rewarding experience. There are a few platforms where you can share your observations and learn from others, such as iNaturalist, BugGuide, and the Maryland Biodiversity Project. When photographing these moths, remember that they are most active during the day and are usually found in the northeastern quadrant of the United States4.
Here are some tips for photographing and observing Virginia Ctenucha Moths:
- Approach them slowly and quietly, trying not to disturb their natural behavior.
- Look for them in open fields, meadows, and forest edges where their host plants are abundant.
- Capture their striking features like the orange head, black and metallic blue body1.
- Try different angles and lighting conditions to showcase their vibrant colors and intricate patterns.
Overall, understanding the classification of the Virginia Ctenucha Moth and being able to tell moths and butterflies apart, along with practicing observation and photography skills, will allow you to better appreciate these fascinating creatures.

I just photographed a ctenuchid moth in Siskiyou County in Northern California. It looks very much like the photo above except the moths here are a bright read on the head instead of orange. How do I post a picture of it? There were dozens of them flying around in the weeds here.
Simply fill in the fields of the Ask What’s That Bug? form and attach a photo. Then send.
I just saw these yesterday at Roessler’s Point, Palos Verdes, CA. They were feeding from the flowers of a Natal plum hedge. Aren’t they far from their natural range?
Without a photo, it is difficult to be certain, but other similar looking moths are found in California, like the Yellow Collared Scape Moth http://bugguide.net/node/view/447 and the Brown Ctenuchid http://bugguide.net/node/view/284059 .
The picture is identical to Ctenucha virginica, but it only lives in the northern U.S. and Canada.
I think same pic just rotated?http://bugguide.net/node/view/385655/bgimage
This posting has now been corrected.
I live in So Cal too. I’ve noticed that Brown Ctenuchas either have red heads and red shoulders, or orange heads and white-orangish shoulders. I’m wondering if the orangish are females. But I have seen an orangish approach a red shoulder with antennae/leg movements, definitely some sort of mating ritual which would tend toward orange = male. What can you tell me. 7-3-2021 and they are out in force this week. The above photo is an orangish type.
