Molecular basis

In 2018, the complete mitochondrial genome of the moth was sequenced using a nanopore sequencer as a single long read. It is the second report of a complete mitochondrial genome of psychid species.[4]

Description

Adults show strong sexual dimorphism.[5] Adult females lack wings and live throughout their life in the larval case.[6] Adult males have functional wings. This is due to that during final instar larvae, male show normal wing discs, whereas those of the female show rudimentary.[7][8]

Ecology

It is a known pest of Citrus and tea cultivation, though it is considered to be polyphagous.[9] It also a known pest of mango, cashew, casuarina, cinnamon, Shorea robusta.[10]
