Roque-Albelo, L. 2003 Population decline of Galapagos endemic Lepidoptera on Volcán Alcedo (Isabela Island, Galapagos Islands, Ecuador): an effect of the introduction of the cottony cushion scale?. Bulletin de l'Institut Royal des Sciences Naturelles de Belgique, Entomologie 73: 177-180.

Notes: By eliminating its food plant, Darwiniothamnus tenuifolius, the cottony cushion scale, Icerya purchasi (Insecta, Homoptera, Margarodidae), may have extirpated three Lepidoptera species (i.e. Semiothisa cerussata, Platyptilia vilema and Tebenna galapagoensis) from the east slope of Volcán Alcedo, Isabela Island, Galapagos Archipelago, Ecuador.
