SCP-2608

An SCP-2608 imago.

Item #: SCP-2608

Object Class: Safe

Special Containment Procedures: The health of all known SCP-2608 populations is to be monitored closely. Steps should be taken to prevent industrial sources from chemically damaging the environments these populations inhabit.

SCP-2608 populations are to be kept at all suitable Foundation facilities and monitored as a priority. In the event that these "Advance Warning Systems" (2608-AWS) experience a decline of any sort, the site manager is to be alerted immediately and precautionary measures are to be taken. Reevaluation of the active radii of various occult, psychoactive, and temporal SCP objects via SCP-2608 subimago testing is pending O5 approval.

As of 12/21/2014, a "doomsday cache" population is to be established at Site-62, and the Site-64 population has been expanded and repurposed to monitor unexplained global population fluctuation in SCP-2608.

Description: SCP-2608 is a largely unstudied mayfly species (Stenonema nephilim) native to the Pacific Northwest. It is thought to have spread across the wetlands of North America in the last two decades , outcompeting related species due to a marginally more efficient metabolism.

SCP-2608 imagines can be distinguished from related species by their relatively larger eyes and relatively more translucent bodies—however, these differences are subtle enough that they cannot be readily identified by unqualified individuals. SCP-2608 subimagines and SCP-2608 naiads cannot be reliably distinguished from related species by any means outside of DNA examination.

SCP-2608 was first brought to Foundation attention when the population experienced a then-inexplicably widespread die-off in the spring of 2005 now thought to be the result of the ten day delay in containment of SCP-1425. The species has since been restored to its former range.

SCP-2608 populations—and, in some cases, individuals—are extremely vulnerable to changes in their environment, undergoing faulty molting and mass death when exposed to even trace contaminants. While this is standard among Ephemeroptera species, SCP-2608's sensitivity extends far outside normal bounds, manifesting in its anomalous properties.

SCP-2608 is vulnerable to psychoactive manipulation and foreign or altered spacetime as though a physical element were present. For this reason, SCP-2608 populations have been cleared for use as an "advance warning system" (2608-AWS) and kept at appropriate Foundation facilities, thereby providing an early warning in case of growth, strengthening, or resumed activity of anomalous phenomena at Foundation Provisional Sites and containment breach at Foundation Sites and Areas.

While the exact chemical manner in which SCP-2608 individuals are affected varies greatly based on the phenomenon in question and its source, there are two "rules of thumb" that can give rough insight into the strength and proximity of the phenomenon;

The general health of an SCP-2608 population can be regarded as an estimate of how close its surroundings are to its natural environment.

An effect strong enough to cause immediate death in an SCP-2608 specimen is strong enough to pose a threat to Foundation operatives.

Phenomena that are harmful to SCP-2608 populations are limited to those that alter their environment in a manner that they are not prepared to compensate for. While this includes many natural phenomena, those that interest the Foundation (and that no measures have been taken to shield 2608-AWS from) include:

Psychoactive fields

Telepathic fields

Temporal distortion

Spatial distortion

Reality distortion

Mere proximity to some SCP objects that do not exert any of the former on their surroundings. It has been theorized that in these cases it is some manner of "presence" surrounding the object that SCP-2608 populations are sensitive to.

SCP-2608 subimagines are particularly at risk; in testing with select suitable SCP objects, individuals consistently perished when brought within the active radius of the object in question, with a very low degree of failure. Preliminary testing suggests that SCP-2608 subimago testing can be used to map the borders of appropriate SCP objects' "area of influence" to a startling degree of accuracy.

Often, SCP-2608 naiads and subimagines will show signs of disturbance by an SCP object at much greater distances than human test subjects; in one noteworthy case, SCP-2608 naiads perished up to 800 km outside of what had previously been thought to be the object's area of influence.

Addendum: - 05/26/2009 - Travel capable 2608-AWS are available upon request for exploration and recovery missions. Contact Dr. Lymph or Site-64 administration for more details.

Addendum: - 12/21/2014 - All known wild SCP-2608 populations experienced a population decline 0.6% higher than expected over the course of the 2014 frost. In addition, all captive Foundation populations have experienced an unexplained 0.5% population decline. 2608-AWS warning allowances have been updated to compensate.

Addendum: - 4/10/2015 - With the exception of the Site-62 population, all SCP-2608 populations have declined a further 1.8%. 2608-AWS warning allowances have been updated to compensate.

Addendum: - 8/11/2015 - Global SCP-2608 population decline has continued to progress at a constant rate. 2608-AWS warning allowances have been updated to compensate and will continually update based on projected background disturbance.
