Moths might seem like summer creatures, fluttering around porch lights and garden blooms. But when the chill of winter hits, they seem to vanish. So, what do the moths do during the winter? Are they hibernating, migrating, or just cleverly disguised? Let’s find out how these fascinating creatures make it through the cold months.
Key Points
- Moths have unique survival strategies during winter, including hibernation, migration, and remaining in earlier stages of life.
- Different moth species have different approaches to winter survival.
- Knowing about their winter behaviours can help create moth-friendly environments in gardens year-round.
Where Do Moths Go in Winter?
While moths may seem like warm-weather fans, they’ve got quite the toolkit when it comes to surviving winter. The first thing to know is that not all moths deal with winter in the same way. Some tough it out in the cold, others head south, and some simply wait for spring to wake them up. Sounds a bit like humans, right?
For those wondering about butterflies and moths go in winter, there are some similarities, but a lot of differences too. Butterflies are famous for their long migrations—think of the Monarch butterfly’s incredible journey to Mexico. Moths, on the other hand, are a bit more versatile. Some migrate, but others hibernate in gardens or remain as larvae or eggs.
Hibernation: Moths in Their Winter Rest
One of the most common winter strategies for moths is hibernation. Like bears snoozing in caves, many moth species go into a deep rest during the winter months. This state, called diapause, slows their metabolism and helps them conserve energy.
You won’t find hibernating moths lounging in hammocks, though. They’re tucked away in all sorts of nooks—underneath tree bark, in leaf litter, or even in crevices in your garden shed. Some species hibernate as adult moths, while others hunker down in their caterpillar or pupa stages.
When it’s freezing outside, moths’ bodies produce glycerol, which acts like antifreeze to protect them from the cold. This is what allows them to stay inactive for months without freezing solid. Compared to butterflies, moths are often more adaptable, using different stages of their life cycle to ride out the winter months.
Migration: Some Moths Don’t Stick Around
For certain species, the solution to winter is simple: don’t stay for it! While butterflies are well-known for their migrations, some moths join the exodus to warmer climates. These are often species from warmer regions who just aren’t equipped to handle the cold, so they’ll migrate to survive.
Take the Silver Y moth, for example. These little travellers take off from Northern Europe, heading south to escape the cold. They fly at night, which makes tracking them a bit tricky, but they manage journeys similar to those of migrating birds.
Although moth migration doesn’t get as much press as butterflies, it’s equally impressive. It’s also a key survival strategy for species that can’t hibernate or withstand freezing temperatures.
Moth Larvae: The Next Generation Sleeps Through Winter
Not all moths tackle winter head-on. Some species have figured out a clever workaround: they leave their future selves to deal with it. By laying eggs in the late summer or early autumn, many moth species ensure the next generation will be ready to hatch when spring rolls around.
The moths that don’t survive winter as adults usually have their offspring tough it out as larvae or pupae. These stages are often much more resilient to cold. Some larvae bury themselves in the soil, while others hide in plant stems or tree bark. The Oak Eggar moth, for instance, spends winter as a caterpillar, hidden away in leaf litter until spring arrives.
Gardeners can play a big role in helping these overwintering stages thrive. By maintaining natural habitats and not disturbing leaf litter or other hiding spots, you can give moths and their larvae a cozy place to survive until warmer weather arrives.
How Understanding Moth Wintering Helps Create a Moth-Friendly Garden
If you’re serious about making your garden a haven for moths, then understanding how they deal with winter is key. Moths aren’t just summer creatures, and their lifecycles often depend on the shelter and food sources you provide all year.
Here are a few tips to make your garden moth-friendly throughout the winter months:
- Leave leaf litter: This provides excellent insulation for hibernating moths and larvae.
- Don’t cut everything back: Overgrown hedges or plants can offer great shelter.
- Plant native species: These help moths at all stages of their lifecycle by providing food and shelter.
- Create a wild corner: Allowing one area of your garden to grow naturally can be a lifeline for moths and other wildlife.
Taking these small steps can help ensure that moths make it through the winter and emerge ready to grace your garden with their beauty in the spring.

FAQs
1. Do all moths hibernate during winter?
No, not all moths hibernate. Some migrate to warmer climates, while others remain as eggs or larvae waiting for spring.
2. How can I make my garden moth-friendly during winter?
Simple steps like leaving leaf litter, planting native species, and avoiding cutting back hedges too early can provide moths with the shelter they need to survive the cold.
3. What’s the difference between moth and butterfly winter behaviour?
Butterflies are more likely to migrate, while moths are adaptable and often hibernate or overwinter as larvae or eggs.
4. Do moths die in winter?
Many moths survive winter through hibernation, migration, or remaining in egg or larval form. Some, however, complete their lifecycle before winter arrives.
5. How does climate change affect moth winter behaviour?
Rising temperatures are shifting moth behaviours, causing some to migrate sooner, while others may face new challenges in surviving unpredictable winters.
