Taxonomy

The holotype of Dolichosticta bilinealis Hampson, 1891: 139, pl. 155, fig. 25, from India, Nilgiris is in the BMNH. comb. n. to Cnaphalocrocis Lederer, 1863, Shaffer et al. 1996.

Dolichosticha subauralis Warren, 1896: 175-176. TL Khasias [Meghalaya]. As syn. in (Globiz) but a Shaffer note on the LepIndex card is ‘MS good sp.’ and Shaffer et al. 1996 list it as a good sp.

Description

A golden-fulvous sp. with chestnut brown and darker brown markings. Two brown sub-median and post-median lines traverse all wings. Note how the post-median line is displaced proximally to the rear of the FW (into the median position) like C. patnalis but unlike Cnaphalocrocis medinalis and C. trebiusalis. Compared with C. patnalis, the dark submarginal shading is less distinct and mainly confined to the apices. Not reliably recorded from Borneo.

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
