OK, I know it sounds crazy, but...
I have seen this Mirid twice. Once in Marlton, NJ and once in Rancocas Woods, NJ.
See the other one here... -- Now here is a Yucca plant bug (Halticotoma valida)...
There is a native yucca in NJ. Yucca filamentosa common name Adam's Needle, Silkgrass, Spanish Bayonet.

Halticotoma valida does have a fairly wide distribution

In 2002 it was found in Washington DC - Google cache of a now deleted document
