Glischrochilus
picnic beetles, beer bugs
Glischrochilus is a genus of small beetles in the family Nitidulidae, commonly known as picnic beetles or beer bugs. The genus contains two subgenera with divergent feeding strategies: Librodor species feed on sap and fermenting plant matter, while Glischrochilus species are predators of soft invertebrates. Most species are characterized by black bodies with contrasting yellow, red, or orange elytral markings. The genus is distributed across North America and Eurasia and includes several agricultural pests.
Histiostoma
Histiostoma is a genus of astigmatan mites in the family Histiostomatidae, characterized by modified brush-like chelicerae adapted for filtering microbes from substrates. The genus exhibits remarkable ecological diversity, with species occupying habitats ranging from bark beetle galleries and insect associations to aquatic environments and decaying organic matter. Many species form heteromorphic deutonymphs (hypopi) specialized for phoretic dispersal on arthropod hosts. Histiostoma includes economically significant species such as H. feroniarum, a pest of cultivated mushrooms, and H. laboratorium, a notorious contaminant of Drosophila research cultures.
