This year I’d like to make my garden a bit more wildlife-friendly. (You can see my previous posts about gardening for bees – Bees’ Needs: Flowers! and Blue (and Violet and Purple) for Bees – by clicking on the links.)

Bees are not the only pollinators that I’d like to encourage in the garden. Hoverflies are important for pollination and their larvae have a valuable role as predators of aphids and other garden pests. (There are always plenty of greenfly around here, so there should be plenty to keep any hoverfly babies munching!)

It can be easy to confuse hoverflies with bees or wasps. (They don’t sting but they mimic stinging insects so that birds are less likely to try eating them.) If you look at the photo of the honeybee below, you can see that there are differences between the common ‘marmalade hoverfly’ and the bee.

The bee here is generally a bit more furry-looking. (You can just see that there is a hairy patch on the front of the bee’s head and that its thorax is also hairy. Compare that to the thorax of the hoverfly, which is shiny and looks almost metallic in the sun.) The hoverfly has much shorter antennae and has just two wings, whereas the bee has four wings. (It’s hard to see that in the photo. You might just about be able to spot the separation at the back edge of the two wings on the nearest side of the bee.)

However, there are many other types of hoverfly (over 270 in the UK) and some look much more like bees than these. There is a difference that will help you tell which is which. Hoverflies have large eyes which cover the front and side (i.e.most) of their faces. A bee has eyes on the side of its face and they are much smaller and an oval shape.

It’s likely that some of the different ‘bees’ I thought I’d spotted in the garden were really hoverflies. Maybe I’ll learn to identify some of them… if I can move quick enough to photograph them!

It’s very worthwhile to grow flowers that will attract these useful little beasties. They have shorter tongues than bees, so aren’t attracted to some of the deeper, bell-shaped flowers (e.g. foxgloves and penstemons) that bees like. Instead they prefer more open flowers where the nectar and pollen is easy to get at. They really like the daisy types like the aster below and umbellifers such as the fennel and wild carrot that grow in the garden here. One of the flowers that I often find them on is the scabious – as you can see from the photos.

I like watching hoverflies dart around amongst the flowers. They are fast and very agile (even flying backwards) and they add to the feeling of life and energy in the garden. I hope to see lots more of them this year – and maybe a few new ones – even if they do fool me into thinking that they may be bees or wasps!
