Mayfly (Revised)

[Achebe]

Mayfly

I watch you flutter in the mid-day sun
so innocent of how you came to be ... Drop the 'so', I'd suggest 
so beautiful; a sight for any one .... Ok with this 'so'
who has the time, and will, to stand and see .... 'No time to stand and stare' - boring and stale
the rainbow colours in your fragile wings. ... 'The rainbow in your xxxxx wings' sounds more immediate. 'Fragile' is tepid. How about something to someone suggest the ephemeral nature of those wings, like the ephemeral nature of rainbows?

Then as you dart within warm beams of light,
it seems to me, the whole of nature sings
its song, and gently shares in my delight. 

I know there was a time of cruelty
when you would kill in order to survive.
I understand, I know it had to be
in order that this pleasant day arrive.
So have no guilt my pretty little one;
accept your day of life under the sun. .... The last 2 stanzas don't appeal to me. I think you can do betters with the opening that you have.

Hi Julius - nice start, weak middle and ending. 
'Innocent of how you came to be so beautiful' sounds very poetic in my head, if you drop the 'so'. Love that line.
Good luck.

Edit: also, good job on the enjambment in L2/L3
