Wingless insects finding pork pie (3)
I believe the answer is:
lie
'pork pie' is the definition.
(I've seen this before)
'wingless insects' is the wordplay.
'wingless' says to take the centre (the wings or sides of the letters are removed).
'insects' becomes 'flies' (fly is a kind of insect).
The middle letters of 'flies' are 'LIE'.
'finding' is the link.
(Other definitions for lie that I've seen before include "Assume recumbent posture" , "Fabrication" , "Tell porkies" , "Assume a horizontal position" , "Porky" .)
