Description
For a key to the terms used, see Glossary of entomology terms.

The wingspan is 23–29 mm. Forewing rosy red, or bright brick red without markings; hindwing pale grey: abdomen whitish with rosy anal segment; the male of this form is dull pink, with the costa and all the veins broadly dark grey and sometimes a trace of the dark outer line of dots; hindwing darker grey; in neither sex is there any tint of yellow or fulvous; the form fulva Hbn. is fulvous rufous with the veins and outer line of spots dark, especially the median vein; - ab. ochracea Tutt is yellow ochreous. without red tints, the outer line of dots marked, and often the median vein and the other veins towards termen; ab. punicea Tutt appears to be a paler and greyer, less fulvous, form of fulva; while pallida Stph.is pale ochreous or bone colour with the costa and veins dark grey and generally a dark shade running below the median vein; this form occurs of two sizes; the larger form may possibly represent the ab. neurica Stph.; ab. transversa Stgr. is distinguished by having the inner and outer lines complete and fully marked across the forewing, which is dark grey.[1]

Biology

Adults are on wing from mid-July to October.

The larvae feed on Carex (including Carex pseudocyperus), Juncus and Iris species. They feed internally in the stems of their host plant.[2]
