This week is Pollinator Awareness Week! Yes, you heard it here first1.
‘So what?’ I hear you say. Well, see, the thing is that without pollinators, we’d
all be in the shit be in serious trouble, because an awful lot of food crops need to be pollinated somehow, and the way most of them get pollinated is by the transference of pollen from flower to flower by insects.
Our main pollinators – as I’m sure you all know – are bees. The trouble is, our honeybees are struggling and nobody really seems to know why. Some blame neonicotinoids (‘neonics’) and other pesticides. Some blame pollution. Some blame modern farming practices and/or the horrible tendency government agencies have for ‘tidying up’ our verges and footpaths and parks, etc2. Some blame honeybee diseases spread by mites. Some say it’s a combination of factors. And some freely admit that they don’t know.
The result, in America, has been the growth of the practice of renting out colonies which are hawked around the farms to pollinate crops. This has its own problems, apparently, from stressing the bees and laying them open to opportunistic infections to bee-rustling.
Now, there are also a lot of native bumblebees, but not only are they in trouble too, it seems that in some countries they are not managing to relocate themselves from areas which have grown too warm for them due to climate change, and are dying out locally.
So what are we left with? Well, there are many, many solitary bees which do a sterling job, and many people don’t even know about them because they tend to be quite small compared to honeybees and bumbles and can easily be overlooked.
And there are hoverflies3.
You may not know this, but hoverflies are considered by many authorities to be the second most important pollinators after bees, and it’s a sad fact that an awful lot of people don’t know how to tell the difference, and so fear them both equally. This leads to a lot of untimely insect deaths4
So, dotted throughout this post are some pictures. Some are bees, and some are hoverflies. Some of the hoverflies look quite a lot like bees, but you will notice a difference in their faces, their eye shape and their antennae (and if you’re extra-observant and look closely, their wings). I’m beginning to learn more about hoverflies and how to identify them, and I am by no means an expert, so I reckon if I can do it, so can you.
What can we do, though, about the pollination problem? Well, unless you want to see an era where thousands of poorly-paid people are put to back-breaking work pollinating flowers with a paintbrush, perhaps it would be a good idea to plant some ‘bee-friendly’ flowers in the garden, for a start, and to go easy on the insecticides?
After all, what’s more important: preventing a famine or having a pretty lawn?
Okay, so that’s a little bit tongue-in-cheek. You should all know by now that I don’t really do scaremongering. But seriously, we would all be in serious trouble without insect pollinators, and we should all take time to think about that.
For those interested, here are a few links for further reading. If you do nothing else, please listen to the podcast. It’s very accessible and easy to understand:
1 – Or maybe you didn’t, but it sounds good, doesn’t it?
2 – For ‘tidying up’ read ‘mowing down everything in sight, including the useful – and pretty – wildflowers and grasses on which our insects depend, and leaving behind a brown stubbly mess.
3 – Well, alright, a considerable number of other insects contribute to pollination, but generally in a smaller or less effective way, according to what I’ve read.
4 – And even fewer pollinators.
