Taxonomy
This species was described by
Alfred Philpott in 1930 using a specimen collected at
Birdlings Flat, Canterbury.

George Hudson (probably 10 March 1800 – 14 December 1871) was an English railway financier and politician who, because he controlled a significant part of the railway network in the 1840s, became known as "The Railway King"—a title conferr ...

This species is named in honour of
Jean Lindsay, the first collector of the species.
The
holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of sever ...
specimen is held at the
Canterbury Museum.
Description
Philpott originally described the species as follows:
It has been hypothesised that the hairs on the hind wings of the male may assist in the release of pheromones attracting the females of the species.
Both the males and females of this species are brachypterous.
This reduction in wing size is rare in male moths.

It is found in North and Mid Canterbury.
As well as its type locality, this species has also occurred at
Kaitorete Spit,
Amberley beach,
at Leithfield beach,
both near
Amberley.
Biology and behaviour
Very little is known of the biology of this species.
The adult moths of this species jump like a flea.
Adult moths have been collected from January to mid April.
Habitat and host species
This species has been collected on active sand dunes or shingle soils covered with cushion plants.
The host plants for the larvae of this species are ''
Raoulia'' mats and it has been hypothesised that the larvae are
detritivorous.
Conservation Status
This species has been classified as having the "At Risk, Naturally Uncommon" conservation status under the
New Zealand Threat Classification System.
This species is at risk because of habitat damage caused by commercial shingle removal and stock trampling.
The main threats to this species at Kaitorete Spit have been recorded as weed invasion, damage to habitat by recreational vehicles, housing development of habitat and predators.
