Connecting with the natural world around us is important for many reasons. It’s proven to help our mental health, it’s enjoyable and fascinating, and it gives us an insight into the rhythms and changes of the life that surrounds us. And during the pandemic lockdown this has taken on more significance than ever.
Over the past few months we have been keeping in touch with the Museum’s youth groups as part of our HOPE for the Future project, which is supported by the National Lottery Heritage Fund. The project is themed around the Museum’s British insect collection and our discussions with the youth groups have triggered a particular interest in the diversity of insects in our outdoor spaces.
A great way to become more observant about the world around you is through photography. During a recent lockdown walk, Youth Forum member William Sharpley took out his camera and captured the beautiful images of insects you can see in this post. Looking at insects more closely made William curious about what he could find in his garden, where he noticed a colony of bees active around a compost bin.
The compost bin is in an old coal bunker. It gets very hot in the sunny weather. I have watched the bees going in and going out of here.
Noticing what animals are present, and learning to identify them, helps to build a picture of how the natural world may be changing.
Bees are a good case study. The image below is of a Tree Bumblebee (Bombus hypnorum). Tree Bumblebees were first recorded in the UK in 2001, and since 2007 they have thrived in our increasing urban environments, with numbers and range rising dramatically. They are now a common sight in gardens, establishing colonies in enclosed spaces above ground. William’s old coal bunker compost heap is the perfect spot.
By noticing new species around us we are reminded that populations of living things change over time. Some species, like the Tree Bumblebee, have become more common, while others, such as the Great Yellow Bumblebee (Bombus distinguendus), are now much rarer than they once were.
Once we know what is around us we can turn our attention to patterns of behaviour. William went on to use his science skills to plan an investigation.
I will be trying to find out if bees are more active during the morning or in the afternoon. I will count the bees going in and out of the nest at different times during the day.
The Youth Forum conducted a similar study earlier in the spring, observing when female Hairy-footed Flower Bees and Honeybees were active and feeding on garden plants. They found that the Hairy-footed Flower Bees foraged mostly in the morning, and the Honeybees in the afternoon.
Feeding behaviour in bees is an interesting thing to study because it may be affected by some pesticides called neonicotinoids. Honeybees exposed to low levels of these pesticides spend less time feeding, and over a long period their reduced food intake causes a hive of bees to decline and become more susceptible to other pressures, such as disease, habitat destruction, or extreme weather.
Rather than relying on a handful of chemicals like neonicotinoids, farmers are now encouraged to use a range of methods to control pests. These include using natural predators – known as biological control – and organic methods.
From these relatively simple observations of the natural world we can gain important information about changing environments. And by sharing what we notice, and encouraging others to do the same, we are better able to understand environmental changes and we’ll feel more connected to nature as a bonus. So head out and start looking!
The Museum’s Youth Forum was established to connect with and learn from local young people. The group meet every month to take part in a programme of activities designed for and by the group.
