Normally a resident of the coastal marshes of Norfolk, Lincolnshire, Yorkshire and Essex, a single specimen of extensaria was found on a tombstone in the Congregational Chapel-yard in Horsham in 1922. It is only that this specimen was found by D. M. G. Price, one of the leading lepidopterists of the time, that this record can be accepted as accurate, it being 17 miles from the nearest source of the foodplant, sea wormwood which was "locally common" on the Sussex coast at the time. (Pratt, 2011).
