Script Moths Papilio Obliterans

Script-Moths (Papilio obliterans) are lepidopteran custodial agents of textual maintenance, classified within the Tower under Archival Fauna and administered jointly by the Bureau of Script Anomalies and the Gallery of Superfluous Marks. Adults are held to a standardized wingspan of 4.7 cm, a figure fixed by the Ninety-Eighth Concordance and verified at each quarterly hatch by the Supervisor of Script. The species consumes text that has become redundant, contradictory, or decayed, converting it without residue into Archival Dust, which is then recovered for binding and preservation work. They do not read. They are, by every account that has been tested, unable to read, and the distinction matters greatly to the offices that maintain them.

Description and life cycle

The adult Script-Moth is a dull grey insect with a dorsal pattern resembling ruled lines, a feature catalogued so early in the species' history that no one now remembers what it was originally mistaken for. Larvae are transparent in the first instar and acquire opacity in proportion to the volume of text they have consumed, a property that permits inspectors to estimate the consumption of a shelf without removing it.

Eggs are laid directly on documents judged ripe for disposition. The preference is not for age — old text that agrees with itself is left untouched indefinitely — but for text that no longer agrees with anything. A folio from the ninth century may be left in place for four hundred years, while a notice posted on Tuesday and contradicted on Thursday will be reduced to dust by Sunday. The Seventy-Second Concordance, Clause 8, permits the direct application of moths to text where disposition has been properly authorized; in practice, the vast majority of consumption occurs without any authorization at all, and the Concordance is generally read afterward, as an explanation.

Function within the Tower

Script-Moths perform the physical eradication of entries under the Redaction Mandate and serve as the final stage of Redaction and Reintegration at the Gallery of Superfluous Marks. Their work is judged not by what they remove but by what remains legible; the standing test is that a redacted page must read as though it had always been that short. Moths that leave a scar — a dangling conjunction, a clause with no verb — are removed from service and released into the Indexing Spires, where Indexing Moths are said to tolerate them.

Because their output is Archival Dust, the species is unique among custodial fauna in producing its own supply chain. Every bound volume in the Tower contains, by weight, a small and unstated fraction of text that has been eaten elsewhere and pressed back into service. The Ninety-Eighth Concordance forbids this fact being printed on a colophon, on the grounds that readers are unsettled by it, a prohibition that has never been tested because no one has been willing to print it.

Incidents

In the winter of the year recorded as 7 Script, a colony was introduced to the sub-basement of the Index of High Administrative Script to clear a duplication of eighteen thousand entries. The colony consumed the duplication, then the entries, then the index of the entries, and was eventually halted only by the accidental introduction of a Lumen-Moss Symbiotic Tincture spill, which the moths find intolerable. The sub-basement was sealed for eleven years. The official account, filed by the duty clerk, records the loss as "a reduction of the record to its essentials," a phrase that has since been quoted in every subsequent inquiry and has never been explained.

The Bureau of Script Anomalies maintains a standing complaint, filed against the Gallery of Superfluous Marks and never resolved, alleging that moths released under Gallery seal have been recovered up to nine floors from their point of release, having crossed an unmarked stairwell while the Gallery was under the impression that the species is sessile. The Gallery's answer — that the moths are sessile, and that the floors in question had moved — was accepted in writing and is now cited as precedent.

Classification dispute

The species' placement is contested. The Ninety-Eighth Concordance classifies Papilio obliterans as an instrument, on the reasoning that a creature employed under seal is an instrument of the seal. The Seventy-Second Concordance classifies it as fauna, and describes it throughout in the language of husbandry, including a provision for winter feed that no office has ever supplied. Neither document is repealed; both are cited in the same proceedings, sometimes by the same clerk on the same day. When a dispute turns on the classification, the standard practice is to cite whichever Concordance is closer to hand and to record afterward that the matter was settled.

"A moth under seal is a moth. A moth under seal is a seal. A moth that has eaten the seal is neither, and is the property of the floor it settles on."

Handling and maintenance

Handlers use Administrative Longhand sparingly in the presence of an active colony, and never in Interrogative Script, which the species treats as a signal to complete an unfinished thought and which has twice emptied a query desk entirely. Anti-Drift Measures are observed on all floors where moths are in service, chiefly the taping of lids.

The standard net is white, to match the dust, and handling gloves are worn at all times by staff on floors 3 through 61. Moths that have consumed a full document are removed to the drying racks for twelve hours before inspection.
