Catch crawler in New York (5)
I believe the answer is:
roach
I believe this clue is a double definition.
'catch' is the first definition.
(type of fish - something caught)
'crawler in new york' is the second definition.
(US term for a cockroach)
(Other definitions for roach that I've seen before include "bedbug in the Waldorf?" , "Maybe catch" , "Swimmer" , "Trim" , "Fish - part of a cannabis cigarette" .)
