With two wings I sprouted, flying! (9)

I believe the answer is:

dipterous

I'm a little stuck... Click here to teach me more about this clue!

'with two wings i sprouted flying' is the definition.
I can't tell whether this defines the answer.

'i sprouted flying' is the wordplay.
'flying' is an anagram indicator (letters fly around into new positions).
'i'+'sprouted'='isprouted'
'isprouted' anagrammed gives 'DIPTEROUS'.

Can you help me to learn more?

(Other definitions for dipterous that I've seen before include "like fly" , "like some flies" .)

I've seen this clue in The Telegraph.
