Giant ant queen

Giant Ant Queen are the queen of Giant ants. They are often deeply burrowed in underground caverns and rarely appear on the surface.

Fallout 3
There are only three Giant Ant Queens in Fallout 3. There is one in the Corvega Factory, one in Marigold Metro Station and one in Shalebridge.

Ant Queens are not very fast, though they do seem to notice you from a distance and shoot Ant Spit with surprising accuracy. The queens are generally considered one of the "boss" characters in Fallout 3 as they have extremely high health (about half that of a Super Mutant Behemoth) making them one of the few creatures in the Capital Wasteland that can survive a Nuka Grenade blast.

Quests

 * A Nice Day for a Right Wedding
 * Those!

Bugs

 * Can sometimes be found stuck in the walls near the ceiling, or may go though walls when near nest.
 * When defeating her guards in Marigold Tunnels (Ant Burrow Section), if she catches sight of you, she is known to appear right behind you for odd reasons, even though clearly she would not fit through that tunnel.

Van Buren
Giant Albino Ant Queens are found in the Hoover Dam Scum Pits. Unlike the Giant albino ant, their exoskeleton is not very pale, but only their cocoon.

Appearances
Giant Ant Queens appear only in Fallout 3, and the Giant Albino Ant Queen was going to feature in the cancelled Van Buren.
