As a professional gardener based in Staffordshire, I often get asked how to support our local wildlife during the colder months. One creature that deserves our attention is the hoverfly. These beneficial insects play a crucial role in pollination and pest control, but they need a bit of help to survive the winter. Here's how you can make a difference.
Quick Answer
To help hoverflies in winter, provide shelter with log piles or insect hotels, maintain flowering plants, and avoid pesticide use. These actions create a favourable winter habitat.
Understanding Hoverflies
Hoverflies are often mistaken for wasps due to their yellow and black stripes, but they're harmless and beneficial. In the UK, they help pollinate flowers and their larvae consume aphids, keeping garden pests in check. However, cold winters in the Midlands can be challenging for them.
Creating Shelter
Hoverflies need safe places to overwinter. You can create shelters easily in your garden.
Log Piles and Leaf Litter
Leave a pile of logs or branches in a quiet corner of your garden. This provides an ideal overwintering site. Similarly, resist the urge to tidy up all leaf litter, as it offers additional cover.
Insect Hotels
Insect hotels can be bought or made from simple materials like bamboo canes and hollow stems. Place these in a sheltered spot to give hoverflies a place to hide from the cold.
Maintain Flowering Plants
Even in winter, some plants can continue to provide nectar. Here are a few you might consider:
- Winter-flowering heathers
- Mahonia
- Ivy (let it flower and fruit)
These plants offer crucial food sources when hoverflies emerge on warmer days.
Avoiding Pesticides
Pesticides can harm hoverflies and other beneficial insects. Instead, try natural pest control methods. Companion planting, for instance, can deter pests without chemicals.
Winter Hoverfly Activity Calendar
Here's a quick guide to what you can do for hoverflies each month:
| Month | Activity | Notes |
|---|---|---|
| November | Create log piles | Ensure they're in sheltered spots |
| December | Plant winter-flowering plants | Consider heather or ivy |
| January | Set up insect hotels | Place away from direct wind |
Frequently Asked Questions
Why are hoverflies important?
Hoverflies are vital for pollination and controlling pest populations. Their larvae eat aphids, reducing the need for chemical controls.
Can I use a pre-made insect hotel?
Yes, pre-made insect hotels are effective, but ensure they have materials like bamboo and are placed in a sheltered location.
What if I don't have room for a log pile?
Even a small bundle of twigs can help. Alternatively, focus on maintaining flowering plants and setting up insect hotels.
