[2] The forewings possess metallic green patches over the outer two-thirds, and the hindwings are grey and unmarked.

[2] The species’ southern limit is The Great Smoky Mountains National Park in the southeastern United States.

[3] Members of the family Noctuidae are holometabolous, meaning they have four life stages: egg, larva, pupa and adult.

[4] Although there is limited data on the specific reproductive cycle of Diachrysia balluca, a 1978 study by Eichlin and Cunningham reared and observed Plusiinae specimens from Canada and the Southeastern United States in a laboratory setting.

[4] Although there is limited data on the lifespan of Diachrysia balluca, a 1978 study by Eichlin and Cunningham recorded the development of Plusiinae specimens from Canada and the Southeastern United States reared in a laboratory setting.

As a member of the Noctuidae family, Diachrysia balluca is a nocturnal species, often flying solely at night.

[4] Moths possess a simple tympanal organ that responds to alternating pressures of sound waves.

[9] Diachrysia balluca feeds on woody plants including common hop, quaking aspen, Canadian woodnettle and species of the genus Rubus.

While there is limited data regarding the economic impact of Diachrysia balluca, larvae of the subfamily Plusiinae have been known to damage crops, vegetables, greenhouse plants and ornamental herbs.

[11][12] Diachrysia balluca is assigned a unique Barcode Index Number (BIN) on BOLD (Biodiversity of Life Database).
