Taxonomy

This species was first described by Edward Meyrick in 1901 using material collected at Makatoku, in the Hawkes Bay, in March.[3] George Hudson discussed and illustrated this species both in his 1928 publication The Butterflies and Moths of New Zealand and his 1939 supplement to that work.[4][5] The lectotype specimen is held at the Natural History Museum, London.[2]

Description

Meyrick described B. tristicta as follows:

♂︎♀︎. 10-11 m.m. Head, antennae, thorax, abdomen, and legs fuscous-whitish. Palpi whitish, second joint with short scale-projection, subbasal and subapical spots of second joint, and basal and subapical spots of terminal dark fuscous. Fore wings whitish, irrorated with fuscous and sprinkled with dark fuscous ; first and second discal stigmata elongate, black, first somewhat before middle ; a round black apical dot : cilia very pale whitish-fuscous. Hind-wings grey ; cilia pale whitish-fuscous.[3]

Distribution

This species is endemic to New Zealand.[1][6] Along with the type locality in the Hawkes Bay, this species has also been collected in Fiordland.[5]

Biology and behaviour
Juncus edgariae

The adults of this species are on the wing in March.[4]

Host species

The larvae feed on the flowers and seed heads of rushes including wiwi (Juncus edgariae) and soft rush (Juncus effusus).[7][8][9]

gollark: Seriously, *how* do you get the "haskell" and "code here" bits out of stuff like```++exec`\``haskellcode here`\`````
gollark: $ help
gollark: I'm still trying to figure out how to parse the codeblock things.
gollark: ++help
gollark: Wow, it does equally badly on kind of generic terms.
