Hover Flies on Your Patio: A Guide to Identification, Attraction, and Control

Hoverflies, those fascinating insects that mimic bees and wasps, are frequent visitors to patios. While they might initially cause alarm due to their appearance, they are generally harmless and even beneficial to your garden. This comprehensive guide will help you understand these intriguing creatures, learn why they're attracted to your patio, and discover how to manage their presence effectively.

Identifying Hover Flies on Your Patio

Hoverflies (family Syrphidae) are easily mistaken for bees or wasps due to their striking coloration. However, a closer look reveals key differences:

• Size and Shape: Hoverflies are generally smaller than bees and wasps, with a more slender body.
• Wings: They possess only two wings, unlike bees and wasps which have four.
• Antennae: Hoverfly antennae are short and usually three-segmented, differing from the longer, more complex antennae of bees and wasps.
• Flight: Their characteristic hovering flight is a dead giveaway. They can remain suspended in mid-air with remarkable precision.
• Coloration: They exhibit a wide array of colors, often mimicking the warning coloration of stinging insects. This is called mimicry and helps protect them from predators. Common colors include yellow, black, orange, and brown stripes or patterns.

Common Hover Fly Species Found on Patios

Several hover fly species are commonly found near patios, attracted by flowers and other sources of nectar. Some examples include:

• European Hoverfly ( Episyrphus balteatus): A common species with yellow and black stripes.
• Marmalade Hoverfly (Episyrphus balteatus): Known for its vibrant orange and black markings. Often seen on flowering plants.
• Drone Fly (Eristalis tenax): Resembles a honeybee but lacks the hairy body and possesses only two wings.

Why are Hover Flies Attracted to My Patio?

Hoverflies are drawn to patios for the same reasons they are drawn to gardens:

• Flowers: Your patio plants, especially those with nectar-rich blooms, provide a vital food source for adult hoverflies. Flowers like lavender, coneflowers, and zinnias are particularly attractive.
• Water Sources: A birdbath or even a slightly damp area can attract hoverflies, especially during dry periods.
• Shelter: Your patio furniture, plants, or other structures can offer shelter from wind, rain, or predators.

Are Hover Flies Harmful?

No, hoverflies are not harmful to humans. Unlike bees and wasps, they do not sting or bite. Their larvae, however, play a crucial role in pest control. Many hoverfly larvae are predatory, feeding on aphids and other garden pests, making them beneficial insects for gardeners.

Managing Hover Fly Populations on Your Patio

While generally beneficial, a large population of hoverflies might become overwhelming. Here's how to manage their numbers:

• Reduce Nectar Sources: If you're seeking to minimize their numbers, selectively prune or remove some of your nectar-rich plants. Focus on removing those closest to your patio seating area.
• Natural Predators: Encourage the presence of natural predators like ladybugs and lacewings, which can help control hoverfly populations.
• Physical Removal: Gently sweep or brush away any hoverflies that are particularly bothersome. Avoid using insecticides as they will harm both beneficial and harmful insects.

Conclusion: Embrace the Hoverflies!

Hoverflies are fascinating creatures that contribute positively to your garden ecosystem. Instead of viewing them as pests, appreciate their beauty and their role in controlling garden pests. By understanding their behavior and implementing some simple management techniques, you can co-exist peacefully with these beneficial insects on your patio. Remember to focus on attracting beneficial insects to maintain a balanced garden ecosystem.
