larva length to 30 mm
Adult: forewing grayish to reddish-brown; lines yellowish, broken; spots outlined with yellow; heavy black spot on basal line, fainter black spots on AM and PM lines near inner margin; hindwing grayish-brown, darker toward outer margin (1)

Life Cycle
overwinters as a pupa; one or two generations per year
The name Himella was first introduced by Dallas in 1852 for bugs of the family Coreidae. Since it is still used as a valid generic name in Heteroptera, and is an older name than the Himella proposed by Grote in 1874, Ozdikmen and Seven proposed that the Lepidopteran Himella be replaced by Kocakina (see PDF doc)
