What is this small black spider found in NY? I found this small, black, spider with a yellow mark at the top of its abdomen, crawling on my desk in my office (located in the Lower Hudson valley in NY). I have never seen a spider like this before. ![Black hairy spider with yellow mark on top of abdomen]( What is this spider, and is it native to NY, or is it an invasive species?
