Wasps that sting

"Do they have a purpose that helps the world go round?"
I wonder, as I dodge the buzzing yellow menace.
His football coloured thorax and menacing buzz sound
Warn us of the danger that is difficult to efface!

These hornet coloured insects always spoil our summer walks
Through the fields and woodland up-slopes where we lay our picnic sheet.
Then out come cakes and goodies, and drinks and popping corks
But the dreaded wasp appears then, for he knows what's good to eat!

We swat and wave and duck and dive, and run and leave our food.
Then the striped beasts settle on it, for they love the thing that's sweet.
Meanwhile we ponder how we can recover what is good,
But this horde of buzzing insects has caused us to retreat.

And if we stay in that place to get back what is ours,
Be sure the little devils will attack us with their sting.
Then swellings, pain and misery will blind us from the flowers
Of a day turned really hateful, though its beauty tries to sing.

The song has turned to discord and the buzz is all that's left
On this brilliant summer's day. We admit dreadful defeat!
The food has been abandoned - of our picnic we're bereft.
And there's nothing of our picnic that's available to eat!

Oh, dreadful, poisonous, monsters; you awful insect horde.
You're the bane of summer's beauty, the destruction of delight.
You buzzing yellow perils; I really can't afford
To hang around when you're about, you're really such a fright!
