Lecanodiaspididae
Lecanodiaspididae is a family of scale insects commonly known as false pit scales or lecanodiaspidids. Members of this family come from all parts of the world but are most numerous in the Far East.USDA Agricultural Research Service Description Adults false pit scales are yellow to reddish-brown and have a waxy, papery test with about eight transverse ridges giving it a corrugated appearance. There is a longitudinal ridge in the center of the test and an anal opening with rolled up edges at the posterior end.Life cycle Members of this family of scales mostly live on t ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coccoidea
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descri ...

Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. Honeydew producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap. The sap continues to bleed after the insects have moved on, leaving a white sugar crust called manna. Ants may collect, or "milk", honeydew directly from aphids and other honeydew producers, which benefit from their presence due to their driving away predators such as lady beetles or parasitic wasps—see ''Crematogaster peringueyi''. Animals and plants in a mutually symbiotic arrangement with ants are called Myrmecophiles. In Madagascar, some gecko species in the genera ''Phe ...
