Invertebrate iridescent virus 31 (IIV-31), also known informally as isopod iridovirus, is a species of invertebrate iridescent virus in the genus Iridovirus.[2]Oniscidea (commonly known by a variety of names including woodlouse, pillbug, slater, rolly-polly, potato bug, et al.) serve as hosts. Infection is associated with decreased responsiveness in the host, increased mortality, and most strikingly, the emergence of an iridescent blue or bluish-purple colour due to the reflection of light off a paracrystalline arrangement of virions within the tissues.[3]

In earlier centuries, blue individuals of otherwise drab oniscidean species had been discovered. They were sometimes interpreted to be new subspecies and were described as such: Ligidium hypnorum coeruleumLereboullet 1843 and L. hypnorum amethystinum Schöbl 1861 (in reference to cerulean and amethyst, respectively). In 1980, the first research was published showing that the phenomenon of blue oniscideans is in fact a disease caused by an iridovirus. The aforementioned 'subspecies' have since been reinterpreted, not as distinct taxonomic entities, but as historical findings of individuals infected with this isopod iridovirus.[4]
In 2014, the 220-kilobase genome sequence of this virus was published.[1] Then in 2018 (as part of the 2018b taxonomy release), it was formally accepted as a species by the International Committee on Taxonomy of Viruses, named Invertebrate iridescent virus 31, and placed in the genus Iridovirus alongside the mosquito-hosted species Invertebrate iridescent virus 6.[2]
