They form a monophyletic group within the suborder Sternorrhyncha, having one-segmented tarsi and a single claw (all other hemipterans have a double claw). They show extreme sexual dimorphism: the more-or-less sessile adult females are wingless and larviform, whereas the motile adult males mostly are winged and lack mouthparts. Within the Coccomorpha, 54 families are currently recognised, of which 20 are known only from fossils and 34 are extant (García Morales et al. 2016).

They are extremely invasive, and many species are serious agricultural pests. They are also emerging models for studies of the evolution of genetic systems, endosymbiosis and plant-insect interactions. ScaleNet was launched in 1995 to provide insect identifiers, pest managers, insect systematists, evolutionary biologists and ecologists efficient access to information about scale insect biological diversity. It provides comprehensive information on scale insects taken directly from the primary literature. Currently, it draws from 23 477 articles and describes the systematics and biology of 8194 valid species. For 20 years, ScaleNet ran on the same software platform. That platform is no longer viable. Here, we present a new, open-source implementation of ScaleNet. We have normalized the data model, begun the process of correcting invalid data, upgraded the user interface, and ...

The list includes all generic names that are currently valid with synonyms, unjustified emendations, homonyms, nomia nuda and misspellings. The list has been compiled from many sources as discussed in the introduction. This is the first list to be prepared in recent years of all generic names and it is in alphabetical order.

Each genus name and its type species are assigned to one of the 53 scale insect families now recognised.

His contributions with colleagues and students include a comprehensive treatise on the economic armored scale insects of the United States, and a series of taxonomic works on armored scales in the genera Abgrallaspis, Crenulaspidiotus, Hemigymnaspis, Melanaspis, and Pseudischnaspis. He is best known for his detailed line drawings and beautiful color photographs. Research of his laboratory has emphasized the biology of the species studied including life history information on more than 20 species. He has undertaken pioneering research using integrated pest management strategies to develop the first arborist and nursery IPM programs. In ornamental landscapes he was among the first to test and promote summer oils for the control of armored scales. As a teacher, he taught courses in such div...
