What is a Comma Butterfly?
The Comma butterfly (Polygonia c-album) is a medium-sized butterfly belonging to the Nymphalidae family, also known as the brush-footed butterflies. It’s easily recognizable thanks to the distinct comma-shaped white mark on the underside of its hindwing. The Comma butterfly is a familiar sight across much of England and Wales and has been expanding its range in recent years.
Comma Butterfly Identification
Identifying the Comma butterfly is relatively straightforward thanks to its unique features. Here’s what to look for:
- Wing Shape: The wings have a very distinctive ragged or scalloped edge.
- Upperwing Colour: A bright orange-brown with dark brown or black markings.
- Underwing Pattern: Mottled brown, providing excellent camouflage when the butterfly is at rest.
- Comma Mark: A small, white, comma-shaped mark located in the center of the underside of the hindwing. This is the defining characteristic.
- Size: Wingspan typically ranges from 50 to 56mm.
Comma Butterfly Habitat
Comma butterflies prefer habitats with a mix of sunlight and shade, often found near:
- Woodland edges and clearings
- Hedgerows
- Gardens with suitable host plants
- Orchards
They need access to nectar sources and suitable host plants for their caterpillars, like nettles, elms, and hop. They are often seen basking in sunny spots, especially on tree trunks and leaves.
Comma Butterfly Life Cycle
Understanding the life cycle of the Comma butterfly can help you appreciate its presence in your garden and support its conservation.
- Eggs: The female Comma lays single, barrel-shaped, pale green eggs on the leaves of host plants.
- Caterpillars: The caterpillars are quite variable in appearance, often mimicking bird droppings for camouflage. They feed on the leaves of host plants. They can be brown, black, or even whitish.
- Pupa (Chrysalis): The chrysalis is angular and brownish, resembling a dead leaf. It hangs from the host plant.
- Adult Butterfly: The adult butterfly emerges from the chrysalis. They typically have two or more broods per year, with adults overwintering to start the cycle again in spring.
Attracting Comma Butterflies to Your Garden
Want to see more Comma butterflies in your garden? Here’s how you can create a butterfly-friendly habitat:
Plant Host Plants
Providing the right host plants is essential for Comma butterflies to breed. Here are some excellent choices:
- Nettles (Urtica dioica): A favorite of Comma caterpillars. Don’t worry, you don’t need to let nettles take over your entire garden. A small patch in a sunny, sheltered corner will do.
- Elms (Ulmus species): Especially wych elm.
- Hop (Humulus lupulus): A climbing plant that provides food for the caterpillars.
Provide Nectar Sources
Adult butterflies need nectar for energy. Plant a variety of nectar-rich flowers that bloom throughout the butterfly season:
- Buddlejas (Butterfly Bush): A classic butterfly magnet.
- Lavender (Lavandula): Provides nectar and a lovely fragrance.
- Sedum (Stonecrop): Late-blooming flowers that are great for autumn butterflies.
- Thistles (Cirsium and Carduus species): A valuable nectar source.
- Verbena (Verbena bonariensis): Tall and elegant, attracting many pollinators.
Create a Sunny, Sheltered Spot
Butterflies need warmth and shelter to thrive. Here’s how to create the perfect environment:
- Basking Spots: Place flat stones in sunny areas where butterflies can bask and warm up.
- Shelter: Plant shrubs and trees to provide shelter from wind and rain.
Avoid Pesticides
Pesticides can be harmful to butterflies and other beneficial insects. Choose organic gardening methods to protect your garden’s ecosystem.
Provide a Water Source
Butterflies also need water. A shallow dish with water and some pebbles for them to land on can be very helpful.
