 The moths are furthermore characterized by an often bilobed praecinctorium, pointed spinula, and the absence of chaetosemata and of a retinacular hook.A gnathos or pseudognathos can be present or absent and is therefore of little diagnostic value, except for several genera of Agroterini, where the gnathos has a well-developed medial process.Food plant use is diverse within Spilomelinae, ranging from ferns over gymnosperms to a wide spectrum of angiosperms.
