Cazador

Cazadores are creatures found in the Mojave Wasteland and Zion Canyon in 2281. Large numbers can be found near Red Rock Canyon, inside Silver Peak Mine, and of course, the Cazador nest. Other groups can be found at the tribal village, around Southern Nevada Wind Farm and also at Callville Bay.

Biology
Cazadores are mutated tarantula hawk wasps with distinctive amber orange wings, a blue-black carapace and blood-red eyes. They have a fast and rather erratic flight movement and a venomous attack which can lead to a quick death if not soon treated with antivenom, though high level or high HP player's may outlast the damaging effects of the venom. The spikes on their back inflate and deflate when idle and attacking.

Cazadores are more common in mountainous regions of the Mojave. They chew wood fiber and mold it into a paper pulp with which they create large basket-shaped nests, many of which can be seen at places such as Bonnie Springs, the road towards Jacobstown, and the boathouse at Callville Bay.

Cazadores are hunters that use their stinging attack to paralyze and kill their prey. It is said that they are recent arrivals and are sometimes in competition with nightstalkers, one of the other major predators in the Mojave wasteland.

Gameplay attributes
While a sting from a young cazador isn't highly damaging, the sting of an adult deals notably more damage. They are very fast and hard to escape from without crippling their wings. They attack in large swarms, and possess a very strong poison. Higher levels of Endurance can give a slight chance of resisting the poison. The only other way to deal with the venom is with antivenom or by using a prophylactic such as blood shield (introduced in Honest Hearts), which temporarily boosts poison resistance.

Curiously, cazadores cannot swim but will always try to follow the player into the water, at which point they will quickly drown. Crippling a wing via V.A.T.S. slows them down immensely, and crippling both wings causes them to have to walk at an extremely slow rate. This also knocks them to the ground for a short period of time.

Cazador
Cazadores are large with distinctive orange wings, a blue-black carapace, blood-red eyes, a spiky upper abdomen, and a high and rather erratic flight speed. Cazadores are common in mountainous regions in the Mojave region.

Young cazador
Young cazadores are often found near other cazadores in mountainous regions (presumably their parents). Young cazadores are identical in appearance to regular cazadores but are about 3/4 to 1/2 the size. Though their poison is weaker than that of the adults, they have an above average Agility, making them rather tricky to hit.

They also prove to be quite a hassle because of their swarming tactic, which involves the entire group swarming their target in an attempt to overwhelm it via numerical strength.

Legendary cazador
The only one of its kind, the legendary cazador has twice as many hit points and significantly more attack power than a normal adult cazador. The legendary cazador is one of the four legendary creatures found in the Mojave Wasteland. It is encountered at the end of the cazador-infested Silver Peak Mine. Sometimes it will show up after the player clears out all the other cazadores or after reaching the second floor of the cave.

Giant cazador (Honest Hearts)
Giant cazadores are encountered all over Zion Canyon as part of the Honest Hearts add-on. They are one of the most vicious creatures in the add-on, and can be found in various locations outside of Eastern Virgin and the Sorrows Camp. They are usually in groups of around three, but it is not uncommon to see them in smaller or larger groups.

Appearances
Cazadores appear in Fallout: New Vegas, and are also mentioned in the graphic novel All Roads, and also appear in the Fallout: New Vegas add-on, Honest Hearts.

Bugs

 * It is very difficult to target the head of a cazador in V.A.T.S. unless it is striking forward with its stinger, the player is right on top of the enemy, is moving on a slope towards the player, or is directly facing the player. Without meeting these conditions the head can never be cycled to as an option in V.A.T.S (only the antennae). This also applies to PCs when using an Xbox 360 controller, but not when selecting targets with the mouse.
 * Cazadores may not appear on areas where they do spawn but upon reloading may suddenly appear.
 * It seems to be possible for them to fall through the map and fly about under it. This will drive your companions crazy, since they will be targeting them but unable to hit them. The cazador cannot sting the NPCs or you either, but they will continue to fly back and forth attempting to attack. If you are on a rise, you will get the name and a health bar when you point a gun at them, but they are invisible and it is clear from the angle of your gun that they are under the map. Attacking with the Ranger Takedown maneuver may fix this bug.
 * Poison does not appear to wear off companions in the 1.2.0.31x patch after combat. Dismissing the companion and re-hiring them at their home location or the Lucky 38 seems to bypass this. It will wear off after 30 seconds, administering stimpaks to companions will cause the whole damage-over-time to be applied at once which could bring them to negative hp.
 * On the PC version, can be fixed by, in the console, selecting a companion and typing.
 * Sometimes (or all the time, if your system is affected), if cazadores are in the area, even if you can't see them, you will hear the poison hissing sound loud and close as if you had been poisoned by them. Essentially, you will hear the sound when a cazador anywhere in your active cell poisons something - the attack might not be on the Courier or a companion, since even a distant cazador battle will trigger the sound.
 * If you use the flamer against them, they sometimes freeze in the air while on fire giving you a chance to kill them or run away.
 * Sometimes a cazador may spawn underground and still be able to attack you, but you cannot attack it. This was confirmed at the Callville Bay cazador's nest. The only way to kill it is to have a companion to do the job.
 * In some cases, you may shoot one of the wings off a cazador and it may keep flying.
 * Sometimes when selecting cazadores on V.A.T.S., it tends to freeze your character from shooting (your character will move around but won't shoot), leaving the cazadores free to attack you for a good 10-15 seconds. Simply restarting the system should do the trick.
 * Rare occurrences of cazadors being able to poison you when they are in no way close enough to do so, seems to only happen in VATS, more research needed.
 * Legendary Cazador seems to just wander around the last portion of the cave without attacking the player until killed, making it a really easy target for the player.
 * In Silver Peak Mine, Cazadores may not show up as red blips on your heads-up display even though they can be targeted using VATS.
