Been killing these also for the tailoring charm. 71 beastlord with mostly masters gear and they are hitting me for 400-750. Good AA xp at 71 though with around 3% per kill.
Also had one drop a regular diamond. Not a blue or a crushed just a plain jane diamond.
Seem to have a poison (it's pretty rare, only seen it once in about a week and a half of hunting them) called Dark Venom. Wish I could say more about it, but I resisted it, only catching its name...

Since I was farming for the Wasp spider silks for the tayloring charm, I did not pay that much attention to anything else. I was surprised at the low level gems that seem part of the loot table.
[edit to add the following] The spiders do not summon. They seemed to have few if any resistance to magic, fire, or cold based spells. While they hit my 72 Druid in the ~500 range, never got poisoned. If another spider was in range, they seemed social. They were not social with the timber lizards or snakes. While the lizards and snakes conned indifferent, the spiders conned amiable to my WoodElf Druid (now that's freaky :)) They had at least 30K to 40K hps.
