Taxonomy
The holotype of Lasiacme mimica Warren,1896: 177, from India, Khasia Hills [Meghalaya] is in the BMNH. It is considered syn. with C. poeyalis (Boisduval 1933: 118) (Globiz), also in the LepIndex as syn. but Shaffer notes on the same LepIndex card 'A good sp.' Here we treat it as such.
- syn. [Marasmia?] eupara Nye (MS name?) TL Sumatra & Irian Jaya (Bradley 1981).
- syn. [Marasmia?] tiona Nye (MS name?) TL PNG (Bradley 1981).
- syn. [Marasmia?] obnata Nye (MS name?) TL St. Helena (Bradley 1981).
Treated in Marasmia (Globiz) but we treat it in Cnaphalocrocis.
Description
A golden yellow and brown sp. with typical Cnaphalocrocis transverse submedian and postmedian lines. Note the specialised tuft of scent scales in the FW cell. The FW costa has a series of dark brown marks like Cnaphalocrocis poeyalis and C. trebiusalis Compared with C. poeyalis this sp. has much wider dark marginal bands on FW & HW. In the males of Cnaphalocrocis poeyalis the large dark patch of scent scales obscures much of the FW subcosta.
Life History
The larvae of most Cnaphalocrocis spp. feed on grasses (Graminaceae) and some are serious crop pests. This is a minor pest of Graminaceous plants and a minor leaf roller pest of Oryza sativa (Rice).
