Asterolecaniidae
Asterolecaniidae is a family of scale insects commonly known as pit scales or asterolecaniids. They typically cause a depression in the host plant's tissues and often cause distortion of the shoots. They are found on a range of hosts but are especially common on oaks, bamboos and a number of ornamental plants. Members of this family occur in most regions of the world but are most abundant in the northern hemisphere.UDSA Agricultural Research Service There are about 25 and 243 recorded .

Scale Insect
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 de ...

Asterolecanium
''Asterolecanium'' is a genus of pit scale insects. ''Asterolecanium'' is distributed worldwide: species have been found in each of the six biogeographic realms, and nearly all of their respective subregions. Many species of ''Asterolecanium'' are destructive to crops and other plants of economic importance such as bamboo and oak, and are therefore considered pests. ''Asterolecanium'' species have been found on at least 37 plant families, most prominently Gramineae (grasses), Palmae (palm trees), and Fagaceae (beech trees). Some species prefer a single host, while others feed on multiple host species. Some feed only on a single part of a plant, such as leaves or stems, while others infest the whole plant. Some create pits in their hosts, depending on the susceptibility of the host plant to damage.

Theodore Dru Alison Cockerell
Theodore Dru Alison Cockerell (1866–1948) was an American zoologist, born at Norwood, England, and brother of Sydney Cockerell. He was educated at the Middlesex Hospital Medical School, and then studied botany in the field in Colorado in 1887–90. Subsequently, he became a taxonomist and published numerous papers on the Hymenoptera, Hemiptera, Mollusca and plants, as well as publications on paleontology and evolution. Personal life Cockerell was born in Norwood, Greater London and died in San Diego, California. He married Annie Sarah Fenn in 1891 (she died in 1893) and Wilmatte Porter in 1900. In 1901, he named the ultramarine blue chromodorid ''Mexichromis porterae'' (now '' Felimare porterae'') in her honor. After their marriage in 1900, they frequently went on collecting expeditions together and assembled a large private library of natural history films, which they showed to schoolchildren and public audiences to promote the cause of environmental conservation.
