Hoplodrina blanda


Hoplodrina blanda is a moth of the family Noctuidae. It is found in the Palearctic ecozone.

Technical description and variation

The wingspan is 31–35 mm. The length of the forewings is 13–16 mm.Forewing fawn-tinged grey, with a fuscous suffusion, with the ground colour sometimes paler, more luteous ochreous, especially in examples from W. Turkestan; costal edge pale; inner and outer lines obscurely marked; the median and praesubmarginal shades distinct; stigmata fuscous grey, with pale annuli; hindwing whitish, grey-tinged towards termen; the veins and cell mark darker; altogether darker grey in the female. Occurs throughout Northern and Central Europe and in Central Asia. These Asiatic examples — from Issyk-Kul; the defile of Little Kisil-su, Tianshan; Kappak, Alexander Mts.; and Ketmen-tjube, Sussamyr Mts.; must be separated certainly as an ab. centralasiae ab. nov. though very possibly a distinct species; the ground colour of the forewing is paler, tinged with pinkish brown along the two folds, and the dark markings stand out more conspicuously; the costal edge is pale; the hindwing, even in the female, is whiter, showing a distinct cell spot. Described from a series of more than a dozen males but only one female, from the above-mentioned localities; the type male from Kappak, the female from Ketmen-tjube. Similar to and confused with Hoplodrina octogenaria and Hoplodrina ambigua. Certain identification requires dissection of the genitalia.
