Just The One

The Hoverfly shown here in flight
Is trying hard with all his might
To find a place to sit and rest
To stretch his wings and look his best

And as you see he's on his own
He has no friends, he is alone.
This suits me well, the theme is met
Just one is odd, so I'm all set.

I enclose two extras today, just because I liked them so much. That's three pictures, odd number - result. Each picture has just one insect - more odd numbers -  result.
