Graellsia isabellae, the Spanish moon moth, is in the silkmoth family Saturniidae. It is the only species in the monotypic genus Graellsia. The species was first described by Mariano de la Paz Graells y de la Agüera in 1849 and the genus was erected by Augustus Radcliffe Grote in 1896.
Range[]
The moth is native to Spain and France.
At the end of April and beginning of May the moth begins to hatch after overwintering in the cocoon. Normally moths from the same parental line won't copulate, so it is necessary to take account of this when the moth is bred in captivity. After copulation the female lays about 100 to 150 eggs on the favoured food plant, pines. The larva hatch after 1 to 1+1⁄2 weeks and begin to eat the very hard pine needles. It takes about one and a half months for the caterpillars to reach the last instar. In the last instar the caterpillars go down from the tree to pupate under leaves on the ground. In this stage the pupae in the cocoon overwinter until the next spring.
Host plants[]
The caterpillar primarily eats the needles of pine trees (genus Pinus). It appears to have difficulty adopting to non-native pine species as a host even within the genus Pinus.
