Ecological Niche

From what I remember of my biology lessons all flora and fauna have an ecological niche. That is an important part to play in the ecosystem; a role that if they were not there to fulfil would result in a negative impact on the rest of the food web.

There are however, some living things that you have to really think hard about to consider the useful part that they play. These are the organisms that are classified as pests. The pesky creatures, who at first glance, seem only to exist on planet Earth to annoy the human population.

One of these pests is Vespula vulgaris, the common wasp. It is a remarkable creature with its striking and instantly recognisable yellow and black colouring. It has a remarkable ability to seek out any human activity that involves sugary and sweet tasting foods. Prime examples being summer picnics or the purchase and consumption of Mr Whippy ice creams.

As soon as these activities have started these creatures tune into the chemical stimuli and appear, buzzing and landing on the sugary food attempting to consume it for themselves.

The arrival of a wasp promotes a variety of different responses depending on the humans involved. Some cool customers will remain still whilst the wasp lands on their hand or face and remain motionless whilst the wasp explores, they know that eventually the wasp will fly off. Others decide that jumping up from their seat (like someone has stuck a red hot poker through the bottom of their chair) whilst screaming and flapping their hands is the way to go. Personally I prefer the first option. It is likely to do me less harm. I am less likely to get stung.

If I am to stay in one place for a reasonable amount of time (say a couple of days at a campsite) then I like to build a wasp trap. This is a remarkably simple and cheap thing to do. You can now buy more expensive models from garden centres and online stores, however I think this trap works equally as well.

But wasps do have an ecological niche. The adults feed on nectar and ripe fruits, therefore they most probably help to pollinate plants and decompose rotting fruit. They are helpful creatures, but this doesn't excuse how annoying the wasp can be.
