The felt scale Acanthococcus azaleae (Comstock) is recorded for the first time on Helianthemum oelandicum (L.) Dum. Cours. in Sweden. Information concerning morphology, host plants, distribution patterns worldwide and biology are included. In Sweden H. oelandicum subsp. oelandicum is endemic to the island, Öland, in the Baltic sea. Öland has a steppe-like vegetation (the Alvar) on limestone bedrock, which is known for its interesting diversity of insects as well as plants.
