Rosy maple moths are small, colorful insects with a wingspan of up to 2 inches.

They are often admired for their bright pink and yellow hues, which can make people curious about their potential danger to humans or plants.

Before venturing into a garden or wooded area, it’s essential to know whether or not rosy maple moths are poisonous.

These moths belong to the silk moth family and are known for their distinctive appearance.

Their larvae, known as green-striped mapleworms, have black stripes on their bodies and two black “horns” above their heads.

As adults, rosy maple moths are generally harmless creatures that pose no significant threat to humans or animals.

However, the caterpillars of the rosy maple moths can sometimes be a concern for plants in their vicinity.

When the eggs hatch, the young caterpillars feed on the leaves of host trees, such as maples.

While these caterpillars might cause some leaf damage, it is essential to keep in mind that they are not poisonous, and neither are the adult moths.

Description and Identification

Appearance

The rosy maple moth (Dryocampa rubicunda) is a unique and colorful insect. Adult moths display a combination of pink and yellow, with variable coloration.

Their wingspan typically ranges up to 2 inches. The caterpillar form, known as the greenstriped mapleworm, has a light green body with darker horizontal stripes.

Geographic Range

These moths belong to the Saturniidae family, also known as the great silk moths. They inhabit North America, with a distribution from:

  • Southern Canada
  • Northeastern United States
  • Florida
  • Texas

The Dryocampa rubicunda can be found in various habitats, from forests to gardens. Their presence is closely associated with their host plants, such as maple and oak trees.

Life Cycle and Habits

Eggs

  • Rosy maple moth females lay eggs in clusters of 10-30
  • Eggs are deposited on food tree leaves
  • Hatching occurs from late April to September

Rosy maple moth females lay their eggs in clusters of 10-30 on the leaves of food trees. The hatching takes place from late April into September.

 

Green Striped Mapleworm

 

Larvae

  • Known as green-striped mapleworms
  • Features:
    • Black stripes along their bodies
    • Two black “horns” above their heads
  • Feed on various species of maple leaves

The larvae, as mentioned earlier, are also known as green-striped mapleworms. They feed on the leaves of various maple species.

Pupa

  • Pupation occurs within a thin cocoon
  • Usually found on the ground or leaf litter

The pupa stage takes place within a thin cocoon, typically found on the ground or among leaf litter.

Adults

Males Females
Smaller in size Larger and more rounded wings
Emerges in late afternoon Mates with males in the evening

Both male and female rosy maple moths emerge as adults in the late afternoon.

Males are smaller in size, while females have larger and more rounded wings. Mating occurs later that same evening.

Habitat and Host Trees

Preferred Trees

Rosy maple moths are typically found in temperate deciduous forests where they prefer to reside on various maple and oak tree species.

Here are some examples of their favorite host trees:

  • Sugar maple (Acer saccharum)
  • Red maple (Acer rubrum)
  • Silver maple (Acer saccharinum)

In addition to maples, they can also be found on:

  • Turkey oak (Quercus laevis)
  • Other oak tree species

Role in the Ecosystem

While rosy maple moths are not considered highly destructive pests, their larvae can cause damage to maple trees.

However, this damage is typically limited to aesthetic issues, as the tree may become partially or entirely bare.

In some cases, a single host tree may have hundreds of caterpillars feasting on leaves.

Adult rosy maple moths lack functional mouthparts, which means they do not feed, making their impact on the ecosystem minimal.

They mainly contribute to the ecosystem through their role in the life cycle of the moth species and by serving as prey for natural predators such as birds and small mammals.

Tree Species Latin Name Preference
Sugar maple Acer saccharum High
Red maple Acer rubrum High
Silver maple Acer saccharinum High
Turkey oak Quercus laevis Moderate
Other oak species Various Moderate

To summarize, rosy maple moths inhabit deciduous forests and favor maple and oak trees.

They play a limited role in the ecosystem, primarily affecting the appearance of trees due to their larvae’s consumption of leaves and their roles as prey for other species.

Are Rosy Maple Moths Poisonous?

To Humans

Rosy maple moths, scientifically known as Dryocampa rubicunda, are considered to be harmless to humans.

  • They do not have a venomous sting
  • Their larvae (caterpillars) have black stripes and two black horns, but these are not poisonous either (source)

These moths can be appreciated for their vibrant colors without fearing any harm to yourself.

To Pets

Similarly, rosy maple moths pose no threat to pets.

  • They do not carry any toxic substances
  • Their caterpillars are not harmful

Note: It is still advised to keep pets from eating them, as consuming non-food items can cause digestive upset.

Comparison Table: Rosy Maple Moth vs. Poisonous Plants

Features Rosy Maple Moth Poisonous Plants
Sting/Venom None Some plants produce harmful toxins
Effect on humans and pets Harmless May cause skin irritation, poisonings or even death
Examples of harmful species N/A Poison ivy, hogweed, hemlock, and parsnip (source)

In conclusion, rosy maple moths are neither poisonous nor harmful to humans and pets.

Their vibrant appearance can be enjoyed without fear. However, always be cautious around plants, as some may be toxic or cause harm.

Threats and Management

Predators

Rosy maple moths face several predators. For example:

  • Birds: Some avian predators of rosy maple moths include tufted titmice, blue jays, and black-capped chickadees.
  • Insects: Parasitic flies, wasps, and predatory beetles are known to prey on both the larvae and adult moths.

Pest Control

In urban landscapes and suburban areas, rosy maple moths might pose a threat to their host trees by defoliating them.

Here is a brief overview of some management options:

  • Natural predators: as mentioned before, birds and insects can help control moth populations
  • Fertilization: providing host trees with appropriate nutrients can improve their resilience

There isn’t a single universally effective strategy for controlling rosy maple moths, as each situation is unique.

As a result, it’s essential to evaluate the specific context and consider the potential benefits and drawbacks.

Control Method Pros Cons
Natural predators Minimal intervention required Cannot guarantee complete control of pest populations
Fertilization Strengthen host trees May not stop moths from causing damage

By considering these factors, it’s possible to devise a well-rounded management plan to deal with the threat of rosy maple moths without causing excessive harm to the environment or the host trees they inhabit.

Bug Control Recommendation Tool

What type of pest are you dealing with?

How severe is the infestation?

Do you require child/pet/garden safe treatments (organic)?

Are you willing to monitor and maintain the treatment yourself?

Rosy Maple Moth

Dear Samantha,
Though we love your descriptive “Butter Cotton Candy Moth” this moth goes by the equally colorful name Rosy Maple Moth

The colors are rosy and the caterpillars feed on the leaves of maple trees.  Back in 2005, deep in our archive, a reader once wrote:  “What a gorgeous sherbert color moth.

We were camping in TN in the great Smokey Mountains of Cosby just this past month (August) when we saw this cute little bug … it moved it’s feet quite fast and it just seemed so cute and happy. Do you know what it is?

I did just discover an even better picture, and I really look forward to hearing back from you.  We asked one of the rangers in the camp, but he had no idea what it might be.

Rosy Maple Moth – Dryocampa Rubicunda
Dear Bug Man,
Now that my friends are aware of how much I have my camera with me to capture unique things, my friend Robin send me this tonight. I can’t find her in your moth section. What a gorgeous sherbert color moth.

Robin and I think it is a Rosy Maple Moth? She took this picture at her home in Bella Vista, Arkansas in Spring 2005 in her carport. Love the site! Amazing how many things I can identify now!
Steph Hart

Hi Steph,
This is indeed a Rosy Maple Moth and we do have photos. As a page gets too large, we either add a new page or split the pages. The Rosy Maple Moth photos can be found on our Saturnid Moth or Giant Silkworm Moth page.

Sorry about the confusion. We do have a search engine to help alleviate any confusion caused by our site becoming such a behemoth.
