Item #: SCP-2819
Object Class: Euclid
Special Containment Procedures: At no time should SCP-2819-1 and SCP-2819-2 be within 100m of each other, except during mandated testing. Both are to be contained in standard small-organism terrariums inside Size-2 Containment Lockers on opposite sides of Site 67. A milkweed plant should be maintained inside each tank for the SCP instances to feed on.
Description: SCP-2819 refers to a set of two male Tetraopes tetraophthalmus, otherwise known as the milkweed beetle. SCP-2819-1 is primarily white with black markings, while SCP-2819-2 is primarily black with white markings. This differs from usual instances of Tetraopes tetraophthalmus, which are red.
SCP-2819-1 and 2819-2 show extreme animosity towards each other, and will fight in a way inconsistent with behavioral patterns of non-anomalous Tetraopes tetraophthalmus. If SCP-2819-1 and 2819-2 are within 100m of each other, they will seek out the other and attack it. The lengths at which they will fight have not been thoroughly tested; it is theorized that if left alone, they will fight to the death. Neither shows any violent tendencies toward other members of Tetraopes tetraophthalmus, even ones disguised by Foundation personnel to resemble the opposite entity of SCP-2819.
Subjects placed near SCP-2819-1 or -2 experience an emotional stagnation. 'Happy' or 'content' persons exposed to SCP-2819-1 will remain so indefinitely, and the opposite is true for individuals exposed to SCP-2819-2. This effect can be countered via Class-B Amnestics. Post-administration, subjects report 'a feeling of loss' for a few hours before returning to normal.
Both SCP-2819-1 and -2 were recovered on opposite sides of the garden belonging to Mr. ██████, a wealthy businessman in █████████, Massachusetts.
Note: High-power microphones located in both containment units detected a rhythmic clicking originating from SCP-2819-1 and -2's mandibles—analysis determined this to be Morse code. Interviews were scheduled and conducted following this development.
