Icerya purchasi Maskell, 1879 - (Australian fluted scale)
The scale attacks citrus and various other plants. It is native to Australia but has spread to North America (first record in California in 1869) and Europe at the end of the 19th century. Apart from direct damage, the excreted honey dew causes the formation of sooty mold which makes fruits unmarketable and blocks sunlight. The female is parthenogenetic and the large ovisac contains around 1,000 eggs. The hatching crawlers disperse through the air.
Mature females are bright orange-red, yellow, or brown and are covered with white or yellowish wax. The fluted ovisac is often twice as long as the body and contains red eggs. The ovisac raises the scale insect which appears to be standing on its head. The young nymphs are also red with dark antennae and brown legs.
