Relating to wings (4)

I believe the answer is:

alar

'relating to wings' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for alar that I've seen before include "using such appendages to fly?" , "Resembling a wing" , "crop retardant" , "Related to wings" , "Relating to wings" .)

I've seen this clue in The Times and the USA Today.
