Chaitophorinae
Guides
Atheroides
Atheroides is a genus of aphids in the family Aphididae, subfamily Chaitophorinae, tribe Siphini. The genus contains at least two described species: Atheroides brevicornis and Atheroides doncasteri. These aphids are found in Europe and North America.
Chaitophorus stevensis
Chaitophorus stevensis is a species of aphid in the family Aphididae, first described by Sanborn in 1904. It belongs to the subfamily Chaitophorinae, a group of aphids commonly associated with woody hosts, particularly willows and poplars (Salicaceae). The species is poorly documented in published literature, with minimal observational records available. It is one of numerous species within the genus Chaitophorus, which comprises primarily North American and Palearctic aphids specialized on Salicaceae.
Chaitophorus viminalis
Chaitophorus viminalis is a species of aphid in the family Aphididae, first described by Monell in 1879. It belongs to the subfamily Chaitophorinae, a group of aphids primarily associated with woody hosts in the family Salicaceae (willows and poplars). The species is documented in North American aphid fauna records and is characterized by its specialized association with willow hosts.
Periphyllus
Periphyllus Aphids, maple aphids
Periphyllus is a genus of aphids in the family Aphididae, subfamily Chaitophorinae, containing more than 40 described species. Species in this genus are primarily associated with maple trees (Acer spp.), though some feed on related host plants such as Koelreuteria. Many species exhibit complex life cycles with polymorphic forms including viviparous females, aestivating dimorphs, and sexual morphs. Several species are invasive pests outside their native ranges, spreading with ornamental host plants.
Periphyllus lyropictus
Norway Maple Aphid
Periphyllus lyropictus is a specialist aphid species feeding exclusively on Norway maple (Acer platanoides). It possesses a distinctive di-symbiotic bacterial system involving Buchnera aphidicola and Serratia symbiotica as co-obligate nutritional endosymbionts. The S. symbiotica strain in this species exhibits a highly invasive phenotype with bacterial motility due to complete flagellum expression, contrasting with the strictly compartmentalized symbiont arrangement found in related aphid species. The two symbionts metabolically complement each other for biosynthesis of essential amino acids and B vitamins.
Periphyllus negundinis
Box Elder Aphid
A North American aphid species specialized on box elder trees. Forms dense colonies on leaves and stems, often becoming conspicuous due to honeydew production and associated sooty mold. The species was first described in 1878 and remains a common, well-documented member of the aphid genus Periphyllus.
Siphini
Siphini is a tribe of aphids within the subfamily Chaitophorinae, first established by Eastop & van Emden in 1972. The tribe includes genera such as Atheroides and Sipha, which exhibit both oviparous and viviparous reproductive modes. Recent taxonomic work has described previously unknown morphs, including alate viviparous females of several species.
