Could be a wandering spider but wandering spiders are brighter I think. I,m no expert I just love spiders. Not sure what you call the front two mandibles in the front but wandering spiders have that same attribute. Hope this helps

The projections near the spider’s mouth are pedipalps, they’re enlarged on male spiders and are used in reproduction. Wandering Spiders (Ctenidae) aren’t established in NY, unless it was associated with something shipped in from out of state that would be unlikely.

Oh I thought these were Alabama spiders only. Do they use those pedipalps to latch onto the female?

ItsyBitsy

In a way, yes. They also act like syringes, they suck up sperm with them and then later use them to transfer it to the female.

Hi welcome to Spider ID. 🙂 This is a male Black Lace-weaver, Amaurobius ferox. Not anything to worry about.
