No image for this species.
Superfamily: Pyraloidea Family: CrambidaeSubfamily: PyraustinaeP3 Number: 801421.10 MONA Number: 4947.10
Comments: This genus was recently revised by Yang et al. (2021), with fifteen species now described worldwide. Four species occur in North America, all of which have been recorded in North Carolina. As described by Yang et al., Ostrinia multispinosa is included in their Clade I, the Ombratalalis Species Group. In North Carolina, this group also includes O. Ombratalalis, a closely related species.
Species Status: This species was described by Yang et al. (2021) in a phylogentic revision of this genus. The type locality is in Florida, but two species collected by J.B. Sullivan in North Carolina were included as paratypes

Adult Markings: As described by Yang et al. (2021), O. multispinosa "is very similar to O. obumbratalis in external appearance, but the forewing transverse markings and dentate subterminal band are somewhat less defined." The head, thorax, and ground color of the forewings is yellowish buff. The base of the forewings is fuscous but the costa and spots are fulvous. Hindwings are also buff (Yang et al., 2021).
Forewing Length: 12.09 ± 0.45 mm (n = 2), males; 10.71 ± 0.23 mm (n = 2), females (Yang et al., 2021)
Adult Structural Features: The male and female reproductive structures are diagnostic and are described and illustrated in Yang et al., (2021)
