Reason: Not really its own mob, rather an in-game phenomenon, as such the separate page has been gathering duplicate information which would fit into the individual jockey, spider, cave spider, skeleton and wither skeleton pages just fine.
Spider jockeys are the rare appearance of a spider or cave spider[BE only] being ridden by a skeleton, stray[BE only], or wither skeleton[BE only].
Spawning[]
Spiders and skeletons[]
There is a 1% chance for a spider to spawn with a skeleton riding it, forming a spider jockey.
Spider jockeys spawned in narrow enclosures can cause the skeleton rider to die of suffocation, due to the spider scaling the walls. They can also spawn in a 1 high space with a transparent block above, so the skeleton is stuck in the transparent block.
Spider jockey spawned with the skeleton's head inside glass.
Bedrock Edition[]
A cave spider can spawn as a jockey, just as a spider can.
If either type of spider is spawned in the Nether (spawned with a spawn egg, commands or monster spawners, since these do not naturally spawn there) and occurs as a jockey, it has an 80% chance for its skeleton rider to be a wither skeleton. If either type of spider is spawned in a snowy biome with a view of the sky, and occurs as a jockey, it has an 80% chance for its skeleton rider to be a stray.
Baby zombie variants can mount spiders and cave spiders. See zombie for details.
Drops[]
The skeleton and the spider each have separate drops when that part of the spider jockey is killed.
Their drops are no different than if the skeleton or spider were standing alone.
Behavior[]
The spider and the skeleton cannot attack each other.
The spider do not attack any entity in Java Edition. The movement of a spider jockey is controlled by the skeleton in Java Edition.
Data values[]
A spider jockey spawns as two separate entities. The spider and skeleton's IDs nor the entity data are any different than if the skeleton or spider were standing alone.

History[]
| Java Edition Alpha | |||||
|---|---|---|---|---|---|
| August 16, 2010 | Notch mentions the concept of spider jockeys in a TIGSource forum post. | ||||
| v1.0.17 |  Added spider jockeys. | ||||
| v1.2.0 |  Skeletons that ride spider jockeys now hold a bow. | ||||
| Java Edition Beta | |||||
| 1.2 | As with spiders, spider jockeys can now climb vertically up walls. | ||||
| 1.5 | Spider jockeys can now be "neutral-hostile" with the addition of rain. The light level is low enough in a rainstorm for the skeleton to not combust, but high enough for the spider to not be actively hunting. In this state, the skeleton shoots the player with arrows, but the spider does not give chase (unless the spider jockey wanders into a shady area) because movement is controlled by the spider. The player can safely observe this kind of spider jockey from a distance of 16 or more blocks away. | ||||
| 1.8 |  Skeletons that ride spider jockeys' bows are now larger and held more realistically (full-sized bows, two-handed, and pulling the arrow back) than in previous versions (in one hand).
| ||||
| Skeletons that ride spider jockeys now fire arrows slightly slower. Their arrows, however, are shot with more force. | |||||
| Java Edition | |||||
| 1.0.0 |  Skeletons that ride spider jockeys now hold their bow with one hand again, but they still have the larger and held realistically bow. | ||||
