Ecology and Behavior
Nocturnal Habits
Underwing moths, including the pink underwing moth (Catocala), are primarily nocturnal creatures. They become active at dusk and spend their nights:
- Searching for food
- Mating
- Avoiding predators
Feeding
The primary food source for underwing moths is the nectar of various flowering plants. Some common food plants for the Catocala include:
- Carronia vine
- Salvia plants
- Other flowering shrubs and trees
In terms of feeding habits, underwing moths are known for their distinctive fluttering movements while searching for food and pollinating plants.
Breeding and Reproduction
During the breeding season, underwing moths exhibit unique behaviors:
- Males emit a “horn” sound to attract females
- Females release pheromones, signaling their readiness for mating
After mating, females deposit eggs on the leaves or bark of the host food plant. The eggs hatch into larvae, which feed on leaves until they pupate and mature into adult moths.
Habitats
Underwing moths inhabit various ecosystems, such as:
- Forests
- Wetlands
- Grasslands
Their ability to blend into tree bark is a key adaptation for their survival. However, some subspecies like the Catocala ilia, are identified as endangered due to habitat loss.
Feature | Underwing Moths | Other Moths |
---|---|---|
Activity Time | Nocturnal (Dusk) | Nocturnal or Diurnal |
Primary Food Source | Nectar | Nectar, Plant Material, or Animal Matter |
Predators | Bats, Birds, Invertebrates | Bats, Birds, Invertebrates |
Reproduction | Mating calls and pheromones | Mating calls, pheromones, or visual cues |
Characteristics of underwing moths:
- Brightly colored hindwings with bold patterns
- Dull forewings that resemble tree bark
- Nocturnal habits, active at dusk
- Predominantly nectar-feeding
Plant Interactions and Conservation
Food Plants and Associations
The pink underwing moth, specifically species like Catocala cara, Catocala junctura, and Catocala palaeogama, interact with various food plants. Some common food plants for these species include:
- Birch
- Oak
- Willows
Rainforest specialists, like the Richmond Birdwing Butterfly, also have specific associations with food plants. One such example is the relationship they have with Syzygium species and shrubs. In some cases, the moths lay their eggs on the petiole of dioecious plants to provide food for their larvae.
Conservation Efforts and Challenges
Conservation efforts have been made in recent years to protect pink underwing moths and their habitats by organizations like Back from the Brink. Dr. Don Sands, a lepidopterist, and other researchers have developed methods to help conserve these moths, such as using stem cuttings to propagate the necessary food plants. Additionally, programs like “Land for Wildlife” work to support conservation efforts by providing land and resources for habitat restoration.
However, there are challenges faced in conserving pink underwing moths, such as their conservation status and the difficulty of accurately identifying some species. A comparison table of two closely related species, Catocala cara and Catocala junctura, can help illustrate these challenges:
Feature | Catocala cara | Catocala junctura |
---|---|---|
Habitat | Deciduous forests | Deciduous forests |
Wing pattern | Wavy lines on forewings | Wavy lines on forewings |
Hindwing color | Bright orange or red | Reddish or pinkish |
Understanding these challenges and continuing research and conservation efforts will help protect the pink underwing moth and its complex interactions with the environment.

I’m sad to know that my visitor is not related to Godzilla, but happy to find out that it is an Underwing Caterpillar. I hope I recognize him/her when he gets his wings.
Thank you.

Thank you.
Many Underwings have brightly colored underwings that are hidden beneath the forewings when the moth is a rest. The forewings are often brown or gray with markings that resemble bark, enabling the moth to disappear into a camouflaged background when at rest.
I had one of these Underwing moths’ on my deck this morning. Didn’t know what it was, thanks for your website, I found out. Shoshone, Idaho.

Found an underwing moth Catacola on the screen of front door around 6 pm on 7/29/18 on Long Island, NY
This specimen is Catocala umbrosa Brou
Thanks for offering this alternative identification.
This is not an alternate identification. I know because I described this species in scientific literature.
Ed Knudson was a good friend of mine and fellow entomologist for the past 40 years, but he was wrong in identifying this species as Catocala ilia. Ed recently died while out on a collecting field trip in Texas.
