Hemiberlesia lataniae , the latania or palm scale , [1] is a species of armored scale insect in the family Diaspididae. Scale insects have a domed, waxy covering which protects the soft-bodied insect below. Armored scales retain the exuviae shed cuticles from the first one or two nymphal stages, and sometimes faecal matter and fragments of the host plant, incorporating these into a hard, protective cover. The exuviae are yellowish-brown and are a noticeable feature near the centre of the scale.

They have no mouthparts and only live for a day or two. The palm scale has a wide range of host plants and has a nearly cosmopolitan distribution , having spread around the world, mostly on ornamental plants. It is known to use members of at least 78 different plant families as hosts, particularly favouring Rosaceae , Arecaceae and Euphorbiaceae.

In some parts of the world, only female insects are present, and they breed by parthenogenesis. The female scales insert their mouthparts into the host plant's vascular tissues and suck the sap.

They have no legs and do not move about as adults. The yellow eggs are retained by the female under her scale and hatch after a few hours.

The newly emerged nymphs crawl away and disperse, losing their legs at their first moult after about two weeks. The second nymphal stage lasts another two or three weeks before moulting to the adult stage. From Wikipedia, the free encyclopedia. Signoret , Catalogue of Life. Retrieved Cornell University Press.
