List of arthropods
Considering that the Dungeon is a dark, dank place filled with moist corners and rotting corpses, it's no surprise that countless bugs and spiders have made it their home. Crawl's many arthropods are by and large some of the weaker opponents you'll encounter, but they shouldn't be underestimated; poisonous attacks are not uncommon, and many of them come with exotic and dangerous special abilities. While there are some exceptions, vulnerability to poison is a common arthropod weakness.
a Worker ant- Poisonous critters that seek out puny adventurers to feast upon.
a Soldier ant- The sort of giant ant that can chomp through armour and shake off stab wounds. Extra poisonous!
a Queen ant- Although a heavy hitter in melee, her slow speed makes her much less intimidating than her minions.
Bees & Wasps
y Killer bee- Painful alone and deadly in swarms, these pack hunters are a menace to the unprepared.
y Queen bee- Although extremely venomous, their lack of maneuverability makes them easy to deal with.
y Yellow wasp- Although slower than killer bees, their stings slow and paralyse their victims.
y Red wasp- An oversized yellow wasp dyed red in the blood of its victims.
s Giant cockroach- Common pests of the upper floors of the Dungeon, they're mostly harmless.
B Goliath beetle- Slow enough for even nagas to kite, but durable enough to make you wonder if it's worth the effort.
B Boring beetle- Beefy, but easily avoided. They tend to turn any floor with rock walls to swiss cheese if left around long enough.
B Boulder beetle- These tanks normally lumber along slowly, but they can suddenly start rolling at break-neck speed.
Moths & Butterflies
b Butterfly- Harmless and pretty and occasionally in the way.
y Vampire mosquito- Pesky undead insects that suck the unwary dry.
y Moth of wrath- These fluttering nuisances are capable of enraging anything they come across.
y Ghost moth- Invisible psychic predators with debilitating poisons.
s Spider- Scuttling poisonous pests. Individually weak, but they come in swarms.
s Trapdoor spider- Cowardly vermin that strike those who walk past their hiding places and retreat underground when injured.
s Tarantella- Strange bugs with bites that disorient their prey.
s Redback- A notoriously venomous arachnid, capable of seriously poisoning even those who are resistant.
s Wolf spider- A powerful spider capable of tearing foes apart even without its venom.
s Orb spider- Unnatural spiders that launch orbs of devastating energy at their foes.
s Giant mite- Bloated, poisonous vermin found in the early Dungeon.
s Giant centipede- Although fragile, their poison stings can be hazardous.
s Scorpion- One of the earliest opponents capable of seriously poisoning careless adventurers.
s Emperor scorpion- The beefiest arthropod of them all, they shrug off blows that would fell lesser bugs.
k Bumblebee- Bigger, solitary bees with a much less terrifying history of player deaths than the killer variety.
