Montaguegramma

Montaguegramma is a fictional genus of nocturnal moths created for a collaborative science-fiction world-building project. It is not a real taxon, and no specimens exist outside the fiction. The genus is described as part of a hypothetical ecosystem on the Montague Archipelago.

In the fictional taxonomy, Montaguegramma belongs to the family Montaguidae within the order Lepidoptera. The taxonomic authority credited is L. Keld (fictional) in 2015.

Species in the genus are small to medium-sized moths, with forewings typically brown or gray, marked by a paler antemarginal line and a distinctive crescent-shaped stigma. Wingspan ranges from 22 to 28 millimeters. The abdomen and hindwings are usually lighter, giving a subdued appearance when at rest.

The genus currently comprises three described species: Montaguegramma insularis, Montaguegramma nocturna, and Montaguegramma montigena. Each is described from specimens collected on different islands within the Montague Archipelago.

Larvae are depicted as folivorous on endemic plants of the archipelago; adults are nocturnal and attracted to light, with a flight season centered in the local dry season in the fictional setting.

Etymology: the name combines Montague, honoring a fictional naturalist, with gramma, from Greek, meaning mark or line.
