Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: SCP-XXXX is to be kept in a 10m x 10m x 10m steel container on Site-██ at all times. SCP-XXXX is to be moved to an identical room monthly so that its original container can be cleaned by D-Class Personnel, then out back into its original container. When SCP-XXXX's room is being cleaned, all larva or eggs of SCP-XXXX discovered are to be terminated immediately. Any adult instances of SCP-XXXX discovered are to be moved to a separate container and treated with the same containment procedures.
Under no circumstances is SCP-XXXX to be exposed to any visible light, and failure to comply will result in immediate termination. Because of this, when Foundation personnel enter SCP-XXXX’s container, all lights within the surrounding hallway must be shut off. SCP-XXX requires no forms of sustenance other than approximately 5 liters of human blood obtained from D-Class personnel on a weekly basis.
Description: SCP-XXXX is a large moth, similar in appearance to the Saturnia Pyri, or the Giant Peacock Moth, with a wingspan of roughly 3 meters, and the rest of its body similarly proportioned. SCP-XXXX seems to possess a form of Night Vision that allows it to see perfectly, regardless of the amount of light presented to it. SCP-XXXX also possesses a proboscis which is about 0.5 meters in length, but is able to extend to up to 1.5 meters when prey is hiding in an area that SCP-XXXX cannot reach. SCP-XXXX uses its proboscis to drain its prey of anywhere between 60.2% to 97.6% of its blood over the course of 5-36 seconds. SCP-XXXX also secretes an unknown substance from its body that, when mixed with the blood it consumes, becomes a material that is at least 73% tougher than diamond. SCP-XXXX uses this material primarily to grow armor from its body.
Once SCP-XXXX is completely protected and believes it is out of danger, SCP-XXXX will begin to lay up to three eggs, coated in a similar material, across its containment over the course of 24 hours. The rate at which SCP-XXXX does this appears to be random, as research has recorded SCP-XXX doing this from 4 to 13 times over the course of a single month. SCP-XXXX does not seem to have any system or reason as to where it lays its eggs, other than that they are in areas of little light and/or high concentrations of moisture. Instances of SCP-XXXX typically hatch after roughly 485 hours. They will then be in their larva stage for 140 hours. Afterwards, they will enter into a Pupa stage for roughly 70 hours, during which other instances of SCP-XXXX will defend it until death, before emerging as an adult instance of SCP-XXXX, after which it is capable of reproducing almost immediately. The lifespan of SCP-XXXX once it has reached this stage is currently unknown.
When exposed to any form of visible light, SCP-XXXX will immediately begin to travel towards it, without any regard for its own physical wellbeing, until it is reached. Exceptions to this are the following:
- Bioluminescent organisms
- Most green light
- Stars or other celestial objects
After it has reached the light, SCP-XXXX's armor will rupture, revealing up to 134 instances of SCP-XXXX in its larva stage. How it does this is is currently unknown, as there is currently an abundance of evidence that indicates SCP-XXXX has many internal organs and functions in common with ordinary moths.
Regardless of circumstance, SCP-XXXX will attack any form of life that possesses blood, internally or externally, until it dies, though SCP-XXXX can be deceived if the target pretends it is already dead.
There are currently 51 adult instances of SCP-XXXX in containment.
Addendum 1: The first known instance of SCP-XXXX was found and contained in the ███████ Jungle in ████████. Any new instances of SCP-XXXX discovered are to be located and contained. It is currently unknown how many instances of SCP-XXXX are in the wilderness.
Addendum 2: Site Director Ronald Clayton requested 40 more containers for SCP-XXXX. Request approved by the O5 council.
Conversation between Dr. Paladine and Site Director Ronald Clayton:
Paladine: I'm just saying, these things could really come in handy.
Clayton: I don't think you understand. The SCP isn't a dog. It is a giant, heavily armoured moth that can drain you of your blood in less than 10 seconds. We've only been able to kill the ones we have with chemical weapons, and we're quickly running out.
Paladine: No, I don't think you understand. We have a golden opportunity here to make an army of these things. Face it: you need a new containment strategy anyway. I had a pet Tarantula as a kid, why would this be any more difficult?
Clayton: You are talking about domesticating over 50 of the most dangerous SCP on this Site, and for what?
Paladine: So that we don't have to keep worrying about these things escaping and multiplying every more than they already have. Hell, maybe we could even use them to off some other SCPs, but it's better than boxing them and letting them fester like you have for, what, nearly 20 years?

Addendum 3: Dr. Paladine submitted a request to attempt to domesticate SCP-XXXX. Request was denied by the O5 Council.
