Glaphyriinae
Forbes, 1923
Glaphyriinae is a of Crambidae described by William Trowbridge Merrifield Forbes in 1923. The subfamily contains approximately 509 in 75 , including well-known genera such as Evergestis and Hellula. of this subfamily are notable for their specialization on Brassicales plants and their ability to detoxify glucosinolates, chemical defenses produced by these plants.

Identification
Glaphyriinae are distinguished from other Crambidae primarily through molecular and larval characteristics rather than consistent morphological . The subfamily includes the tribes Glaphyriini and Dichogamini. Some , such as Chalcoela, contain with distinctive including predatory larval in nests.

Diet
predominantly feed on plants of the Brassicales. They are able to digest glucosinolates, the characteristic chemical defenses of this order. The Chalcoela includes at least one , Chalcoela iphitalis, whose larvae are predatory on (Polistes) larvae inside their nests.
Host Associations
- Brassicales - larval Primary ; can detoxify glucosinolates
- Polistes metricus - predatory of Chalcoela iphitalis on larvae in nests
Behavior
females of Chalcoela iphitalis have been observed approaching nests at night when adult are less alert, laying on the exterior of nests for to enter .
Ecological Role
Most function as on Brassicales, contributing to and - interactions. The Chalcoela represents a rare case of within , with larvae acting as of larvae. This also serves as for , including Calliephialtes grapholithae ().
Human Relevance
Some are agricultural pests on Brassicaceae . The glucosinolate detoxification capability of has attracted scientific interest for understanding biochemical . The unusual predatory of Chalcoela species in nests has been documented in citizen science and ecological research contexts.

Systematic History
The was established by Forbes in 1923. Modern relies heavily on molecular , with Regier et al. (2012) confirming Glaphyriinae as a distinct lineage within . Solis (2009) transferred several western hemisphere from Cybalomiinae to Glaphyriinae.
Tribal Classification
Glaphyriinae contains two recognized tribes: Glaphyriini (Forbes, 1923) and Dichogamini (Amsel, 1956). The tribe Glaphyriini includes the Glaphyria and the economically significant genus Hellula.
Biochemical Specialization
The ability to feed on Brassicales is relatively uncommon in due to glucosinolate defenses. Glaphyriinae share this capability with some and certain , representing of detoxification mechanisms.
