This article is about regular spiders. For venomous dark-blue spiders found in mineshafts, see Cave Spider. For the Spider being ridden by a skeleton, see Spider Jockey.

Spiders are common neutral mobs that have the ability to climb walls.

Spawning[edit]

Spiders spawn in the Overworld in 3×3×2 space on solid block(s) (they need only 1 solid block beneath) at a light level of 7 or less, in groups of 4. The top blocks can be transparent, but not solid.

In Bedrock Edition, leaves may spawn one spider provided that there are 3×3×2 spaces around it; therefore, forested biomes have a greater amount of spiders. Spiders never spawn in groups greater than 1.

Spider spawning on a single block.

Monster spawners[edit]

Spider spawners are found in 25% of dungeons. They also spawn from spawners in hidden rooms surrounded by cobwebs in woodland mansions.

Status effects[edit]

This feature is exclusive to Java Edition.

On hard difficulty, spiders occasionally spawn with status effects. For each pack spawn, there is a (10×clamped regional difficulty)% chance of the game applying a status effect. If it decides to do so, then it selects the effect. The spider can spawn with following effects:

Speed (40% chance)
Strength (20% chance)
Regeneration (20% chance)
Invisibility (20% chance)

The effect is then applied to all entities within the pack for the maximum amount of time possible.

If the Invisibility status effect is applied to a spider, its eyes remain visible.

This does not apply to cave spiders nor in Bedrock version.

Drops[edit]

0–2 String. The maximum is increased by 1 per level of Looting, for a maximum of 0-5 string with Looting III.
5 experience when killed by a player or tamed wolf.
A ¹⁄₃ chance of dropping a spider eye when killed by a player or tamed wolf. The maximum amount of spider eyes is increased by 1 per level of Looting. The chance of a spider not dropping any spider eyes can be found using the formula 2 / (Looting Level + 3). For example, Looting III gives a ¹⁄₃ chance of not dropping any spider eyes. All other amounts have an equal chance of occurring.

Behavior[edit]

Spiders are hostile to players and iron golems as long as the light level immediately around them is 11 or less; otherwise, they do not attack unless attacked. Hostile spiders see up to 16 blocks, continuing to chase even when exposed to well-lit locations. If a spider sustains damage from a source other than a direct attack, such as falling, its hostility is reset.

Spiders can climb up over blocks but not overhangs or on ceilings. If a spider cannot find an ideal path to the player (when a player goes behind or on top of a wall), it approaches as close as it can to the player's position from the outside or below (as it can see through blocks), and proceed to climb the wall vertically until it gets to the top, even if it loses its aggression toward the player. Additionally, when a spider loses its aggression on the player, it continues moving forward blindly for 2 seconds. This behavior causes the spider to climb up any walls in its path. If a spider tries to go through the world border, it starts climbing the world border instead.

If shot with arrows whereas outside of the detection range, spiders turn and run in the direction from which the arrow was fired. If the player moves away, the spider continues following the same path unless the player enters detection range, in which case the spider changes direction and attacks.

Even though spiders do not inflict the Poison status effect, they are immune to it. Therewithal, they are immune to the slowing applied to most mobs when walking through cobwebs.

Spiders leap on their targets at close range. A spider that is swimming in 1-block-deep water pounces on nearby enemies upon touching the submerged floor.

Spiders flip onto their backs when they die, unlike all other mobs, which land on their sides.

Spiders are immune to the slowing applied to most mobs when walking through cobwebs.

They were the first arthropod to be added to the game. As all arthropods, the Bane of Arthropods enchantment inflict Slowness IV and more damage to spiders.

Variants[edit]

Spider jockeys[edit]

Main article: Spider Jockey

There is a 1% chance for a spider to spawn with a skeleton riding it, forming a spider jockey. In the Nether, a spider (spawned with a spawn egg, commands or spawners, since these do not naturally spawn there) has a 0.8% to spawn a wither skeleton on its back and form a wither jockey instead. In snowy biomes, a spider has a 0.8% to spawn a stray on its back and form a stray jockey instead. A spider jockey can also be spawned by the command /summon spider ~ ~ ~ {Passengers: [{id:skeleton}]}.
