Early Cretaceous mealybug herbivory on a laurel highlights the deep-time history of angiosperm-scale insect associations.

Insect fluid-feeding on fossil vascular plants is an inconspicuous and underappreciated mode of herbivory that can provide novel data on the evolution of deep-time ecological associations and indicate the host-plant preferences of ancient insect herbivores. Previous fossil studies have documented piercing-and-sucking herbivory but often are unable to identify culprit insect taxa. One line of evidence are punctures and scale-insect impression marks made by piercing-and-sucking insects that occasionally provide clues to the systematic identities and relationships of particular insect herbivores.

ScaleNet: a literature-based model of scale insect biology and systematics.

Scale insects (Hemiptera: Coccoidea) are small herbivorous insects found on all continents except Antarctica. 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.

Scale insect species names that have been combined with the genus name Dactylopius Costa (Hemiptera: Sternorrhyncha: Coccomorpha).

The genus Dactylopius is the only genus at present in the family Dactylopiidae. Since the name Dactylopius was proposed in 1829, however, numerous other species names belonging to different families of scale insects have been combined with it and these are also listed. The present status and the family placement are also given for each species.

Description of a new species of Odonaspis Leonardi (Hemiptera: Coccomorpha: Diaspididae) from Australia.

The adult female of Odonaspis bouldersensis Ben-Dov, new species, collected in the Boulders National Park, Queensland, Australia, off a species of Poaceae, is described.
