Jacqui has been watching this little fellow grow larger and larger over many months. During daylight hours he lives in exactly the same location, between two bricks on the south-facing wall of our home, though at night he ventures out onto a very basic web close by. We believe it to be a fly catching jumping spider, but I have not been able to verify this via the Internet, nor via my South African wildlife books (Nicholas - can you help?).
Anyway, from a tiny insect to something that is now quite large (the body seems to be between 10 and 15mm), he has lived in the same spot and has no aversion whatsoever to being photographed close-up. Mind you, he did have quite a large meal to contend with on the day. Not sure what it is, but I think it's the remains of a bee.
And while he may not be dangerous to humans, tell that to the thing that is being devoured!
Title, of course, from the song by Michael Jackson
