Die Art wurde aus Arizona (USA) beschrieben und kommtnach Angaben aus Nordamerika in den USA und im Norden Mexikos vor.

Ich habe die Originalarbeit von Martinez & Coutin (1985) noch nicht studiert. Das Abstract dieser Arbeit auf CAB International (1986: 156) ist allerdings recht aussagekräftig: „687 MARTINEZ, M.; COUTIN, R. (A new occasional pest: the American dried-plant moth.] Un nouveau ravageur occasionnel: Ia phalene americaine des plantes seches. Phytoma (1985)]'1o. 368, 40-41 [Fr, 3 col. fig.] Laboratoire de Faunistique Eco-logique, INRA, Versailles, France. Larvae of ldaea bonifata are reported infesting herbarium specimens in France on 4 occasions in 1968-82. This geometrid is a native of the south-western USA and Mexico and has occasionally been reported from Europe before. The adult, larva and pupa are illustrated and notes on the biology and injuriousness are provided. The larvae appear to develop exclusively on dry plants, attacking the flowers, leaves, roots and rhizomes. Seven kinds of dried plants that were infested in France are listed. It is suggested that various herbarium, aromatic and medicinal plants could be infested. Larval development appears to take about 2 or 3 months. While 3 or 4 generations a year are possible, populations are highest at the end of autumn, in winter and at the beginning of spring, and it is in this period that damage has been reported. It is not known whether I. bonifata can survive out of doors. Possible control measures discussed are burning infested material and the use of insecticides with a vapour action such as dichlorvos.”
