Erythraeidae
Erythraeidae is a family of predatory mites in the order Trombidiformes. Adults are free-living, fast-running predators with long legs adapted for pursuit. Larvae are ectoparasites of various arthropods, including harvestmen, spiders, bees, and grasshoppers, using a stylostome to feed on host body fluids. These mites are typically oval, relatively large for mites, reddish in color, and densely hairy. The family belongs to the superfamily Erythraeoidea within the diverse group Parasitengona, which includes velvet mites, chiggers, and water mites.
Erythraeinae
Erythraeinae is a subfamily of mites within Erythraeidae comprising 26 genera. Larvae are parasitic on other arthropods, while nymphs and adults are free-living predators of small insects. The subfamily exhibits substantial morphological differences between parasitic larvae and free-living active stages. Members have been documented across multiple continents with notable diversity in China.
Eupomphini
Eupomphini is a tribe of blister beetles (Meloidae) comprising approximately 7 genera and more than 20 described species. Members exhibit hypermetamorphosis, a complex developmental pattern involving dramatically different larval forms. The tribe includes notable genera such as Tegrodera (iron cross blister beetles) and Cysteodemus (desert spider beetles). Species are primarily distributed in arid and semi-arid regions of North America.
Lebertioidea
Lebertioidea is a superfamily of water mites (Hydrachnidia) within the order Trombidiformes. Members are aquatic arachnids found primarily in freshwater habitats across the Holarctic region. The superfamily comprises approximately 13 genera distributed among several families including Sperchontidae, Anisitsiellidae, Oxidae, and Torrenticolidae. Larval stages are parasitic on various aquatic insects, while post-larval instars are free-living predators.
Zonitis bilineata
Zonitis bilineata is a species of blister beetle in the family Meloidae, first described by Thomas Say in 1817. It is distributed across North America, with records from Canada (Ontario, Québec) and the United States (Vermont). The species belongs to the genus Zonitis, which comprises small to medium-sized blister beetles. Like other meloids, it possesses chemical defenses and has larvae that are parasitic or predatory on other insects.
