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).
