Lymantria ninayi is a species of moth of the family Erebidae. It is found in Papua New Guinea.
It is a pest insect and can cause major damage to forests. In particular, Pinus species, which are introduced in Papua New Guinea, can be completely defoliated by the larvae. Plantations on New Guinea suffer from outbreaks once every seven to nine years.
The native food plants of the larvae are Casuarina species. The larvae feed on the needles. Young larvae feed on young needles, while older larvae feed on older needles. They only consume a small portion of a needle, the rest drops to the ground. Pupation takes place in the needles on the tree or on the ground in a cocoon made of tied up needles.

Lymantria ninayi is een nachtvlinder uit de familie van de spinneruilen (Erebidae), onderfamilie donsvlinders (Lymantriinae).
De soort komt voor op Nieuw-Guinea. De vlinder is een plaaginsect en kan grote schade in de bosbouw teweegbrengen. Met name bomen uit het geslacht Pinus, die voor de bosbouw in Nieuw-Guinea zijn geïntroduceerd, kunnen door de rupsen volledig ontbladerd worden. De bosplantages op Nieuw-Guinea worden eens in de 7 tot 9 jaar getroffen.
De inheemse waardplant is Casuarina. De eitjes worden afgezet in de oksel van een tak op de bast van de boom. Op deze plaats zijn ze beschermd tegen regen. De rupsen eten van de naalden, jonge rupsen van jonge, oudere van oude. De rupsen eten slechts een klein deel van de naald, de rest valt naar beneden. Verpopping vindt plaats in de naalden aan de boom of op de grond en een cocon van samengebonden naalden.
