Izatha metadelta is a moth of the family Oecophoridae. It is endemic to New Zealand, where it is known from the North Island only. It is rare north of Waikato and the Bay of Plenty.
Taxonomy
This species was first described by Edward Meyrick in 1905 using three specimens collected in Wellington by George Hudson. The lectotype specimen is held at the Natural History Museum, London. Hudson discussed and illustrated this species in his 1928 publication The Butterflies and Moths of New Zealand.

The wingspan is 15–18.5 mm for males and 19–25.5 mm for females. Meyrick first described this species as follows:
♂. 17 mm, ♀. 19-25 mm.
Begin with the source’s own compact description: “Izatha metadelta” is species of insect. The dossier treats that line as a proposition to test through Izatha, metadelta and species, not as a finished interpretation.
Why this record matters
The phrase “species of insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 1, 2026. The linked authority identifier is Q6101711. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1905 and 1928.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
