One of the most noteworthy things about Black Lace Weavers is that they practice "matriphagy." Or to put it another way, the baby spiders eat their mothers alive! This typically occurs about a week after the babies hatch. Wildlife photographer Steve Downer actually caught this behavior on "film." Check out his video on YouTube.
The individual spider that I found in my doorway will be spared this particular fate because he is a male. Lucky him. You can tell that it is a male by the presence of the two boxing glove like appendages that protrude from the front of his head. These are the pedipalps, or just palps, which are used during mating.
