Adeixis griseata
species of moth endemic to New Zealand
Adeixis griseata (also known as the swamp looper) is a species of moth of the family Geometridae. It is endemic to New Zealand and has been collected in the North, South and Chatham Islands. This species inhabits poorly drained or swampy areas. As at 2017 the host plant of this species is unknown however it has been hypothesised that the host plant may be Schoenus brevifolius or another common sedge. Adults have been observed on the wing from October until January.
Taxonomy
This species was first described by George Vernon Hudson in 1903 from a specimen collected by Alfred Philpott at Seaward Moss in Southland and named Dichromodes griseata. There was some debate between taxonomists as to whether this species was distinct from the Australian species Adeixis inostentata. However, in 1920, after comparing specimens of both species, Philpott concluded it was distinct enough to be regarded as its own species. Louis B. Prout placed this species within the genus Adeixis in 1910. The syntype specimens are not held in Te Papa but J. S. Dugdale hypothesised that one of the syntypes may be held at the Natural History Museum, London under the species name Paragyrtis inostentata (now known as Adeixis inostentata).
This brief starts where responsible research should: with the source description of “Adeixis griseata” as species of moth endemic to New Zealand. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of moth endemic to New Zealand. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 16, 2025. The linked authority identifier is Q15683775. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017, 1903, 1920 and 1910.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
