Dactylopiidae
Cochineal Insects
Dactylopiidae is a family of scale insects (Hemiptera) comprising the single genus Dactylopius, commonly known as cochineal insects. These insects are economically and historically significant as the primary source of carmine, a vibrant red dye derived from carminic acid that the insects produce as a defensive compound. The family has been used for dye production since at least the 10th century in the Americas and became the second most valuable export from the New World during the Colonial Period. Some species serve as biological control agents for invasive cacti, while others are agricultural pests of cactus crops.
Dactylopius confusus
American cochineal bug
A scale insect in the family Dactylopiidae, commonly known as the American cochineal bug. The species has been studied for its hemolymph lipoproteins, which share functional similarities with insect lipophorins. It is one of several cochineal species historically exploited for carmine dye production.
Eosalpingogaster
Eosalpingogaster is a genus of flower flies (Syrphidae) established by Hull in 1949 and elevated to full generic status based on adult morphology, biological data, and molecular phylogenetics. Species in this genus are specialized predators of carmine cochineal insects (Dactylopius spp., Dactylopiidae), which are the source of carminic acid used in red dyes. The genus includes multiple species, with two new species described in a 2011 revision.
Margarodidae
ground pearls, cottony cushion scales, giant coccids, giant scale insects
Margarodidae, commonly known as ground pearls or cottony cushion scales, is a family of scale insects within the superfamily Coccoidea. The family has undergone significant taxonomic revision, with many former subfamilies (including Monophlebidae, Matsucoccidae, Xylococcidae, and others) now elevated to family status. The current Margarodidae sensu stricto is monophyletic and includes genera such as Margarodes, Porphyrophora, and Eurhizococcus. Members exhibit diverse life histories, with some species being subterranean root feeders and others above-ground foliar feeders. Several species are economically important as agricultural pests or historically as sources of natural dyes.
