Today I saw the dragon-fly
Come from the wells where he did lie.
An inner impulse rent the veil
Of his old husk: from head to tail
Came out clear plates of sapphire mail.
He dried his wings: like gauze they grew;
Thro’ crofts and pastures wet with dew
A living flash of light he flew.
Alfred Lord Tennyson
Well something like that although this one was encountered in dry woodland devoid of grass and certainly devoid of dew.
There is a handy key to Australian Dragon and Damselflies <HERE> from which I learnt that this is a Tau Emerald (Hemicordulia tau).
