Late afternoon with the setting sun shining through the trees, just the right setting for a group of dragonflies to flutter back and forth over the grass. Finding a suitable stem they would alight for a short while, then dance off with their transparent wings displaying jewel like red splashes.
A bit of investigation identified them as Graphic (or banded) Flutterers Rhyothemis graphiptera
and the name seems very appropriate as they were superbly demonstrating with this afternoon's display.
