Insects found in place across street (7)
I believe the answer is:
locusts
'insects' is the definition.
(locust is a kind of insect)
'place across street' is the wordplay.
'place' becomes 'locus' (I've seen this before).
'across' means one lot of letters goes inside another.
'street' becomes 'st'.
'locus' enclosing 'st' is 'LOCUSTS'.
'found in' acts as a link.
(Other definitions for locusts that I've seen before include "can be a plague" , "Strippers" , "Destructive grasshoppers" , "Grasshoppers of warm regions" .)
