Tiny Pollenator

A small 1/2 inch (1cm) flower with a tinier fly aboard brought to mind a quote:

Great fleas have little fleas upon their backs to bite 'em,

And little fleas have lesser fleas, and so ad infinitum.

And the great fleas themselves, in turn, have greater fleas to go on;

While these again have greater still, and greater still, and so on.
[1872 A. De morgan Budget of Paradoxes]

Of course, when it comes to pollination everyone wins I think... especially we humans.
