People usually talk about aphids like they are already explained. Tiny green bugs. Bad for the roses. Spray them, squish them, move on. That is not wrong. It is just a very small version of the story.
Aphids
Guides
Aphidini
Aphidini is a tribe of aphids within the subfamily Aphidinae, containing approximately 30 genera divided into two subtribes: Aphidina and Rhopalosiphina. The tribe includes economically significant genera such as Aphis (containing the black bean aphid and cotton aphid) and Rhopalosiphum (containing the bird cherry-oat aphid and green peach aphid). Members are small, soft-bodied sap-feeding insects with complex life cycles often involving host alternation between primary woody hosts and secondary herbaceous hosts.
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.
Calaphidinae
Calaphidinae is the second-largest subfamily in the family Aphididae, comprising more than 60 genera and over 360 described species. The subfamily includes aphids primarily associated with woody host plants, particularly birches (Betula), oaks (Quercus), and related tree species in the families Fagaceae and Betulaceae. Recent molecular phylogenetic studies have substantially revised the classification of Calaphidinae, establishing eight tribal divisions and revealing that the group is paraphyletic with respect to the former 'Saltusaphidinae'. The subfamily shows complex evolutionary patterns involving host plant shifts and geographic expansion from an Eastern Palaearctic origin.
Cinara
giant conifer aphids, conifer aphids
Cinara is a genus of aphids comprising approximately 200-243 species, commonly known as giant conifer aphids. These insects are specialized feeders on conifers in the families Pinaceae and Cupressaceae, including pines, firs, spruces, cedars, and cypresses. Molecular studies indicate their tribe Eulachnini represents the basal group for other aphids. Several species are significant pests of cultivated Christmas trees, particularly Fraser fir production in the southeastern United States.
Deraeocoris nebulosus
Deraeocoris nebulosus is a predatory plant bug in the family Miridae. It is native to North America and has been documented from the northeastern United States through the mid-Atlantic and into the South. The species is a significant biological control agent in agricultural and ornamental systems, feeding on mites, aphids, and other small arthropod pests. It has been studied extensively for its role in managing European red mite in Virginia apple orchards.
Greenideinae
Greenideinae is a subfamily of aphids (Aphididae) comprising approximately 179 extant species across 18 genera in three tribes: Cervaphidini, Greenideini, and Schoutedeniini. Species are primarily distributed in eastern and southern Asia, with many exhibiting specialized associations with woody host plants, particularly in Fagaceae. The subfamily has been extensively studied for its complex symbiotic relationships with microbial associates, including the primary endosymbiont *Buchnera aphidicola* and diverse secondary symbionts.
Nomotettix cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.

Ovatus is a genus of aphids in the family Aphididae, currently treated as a synonym of Ovatomyzus. The genus was historically recognized for species associated with various host plants, though modern taxonomic revisions have consolidated many of these into Ovatomyzus. Records indicate distribution in parts of Europe including Denmark, Norway, and Sweden.
Panaphidini
Panaphidini is a tribe of aphids within the subfamily Calaphidinae, established by Oestlund in 1923. The tribe comprises approximately 50 genera divided into two subtribes: Myzocallidina and Panaphidina. Many genera are associated with woody host plants, particularly in the families Fagaceae, Betulaceae, and Salicaceae. The tribe includes economically significant pests such as species of Tinocallis and Monellia.
