Calaphis leonardi
Calaphis leonardi is an aphid species in the family Aphididae, subfamily Calaphidinae. The species was described by Quednau in 1971. Like other members of the genus Calaphis, it is likely associated with coniferous hosts, though specific host records for this species are not well documented in available literature.
Cinara costata
Mealy Spruce Aphid
Cinara costata is a large aphid species in the family Aphididae, commonly known as the Mealy Spruce Aphid. It feeds on conifers, particularly spruce (Picea spp.), and is native to Europe where it has been documented in Great Britain, Denmark, Belgium, and France. Like other Cinara species, it produces honeydew that attracts ants and wasps. The species was first described by Zetterstedt in 1828 from specimens collected in Scandinavia.
Essigella
American Pine Needle Aphids
Essigella is a genus of aphids in the family Aphididae, commonly known as American pine needle aphids. Species in this genus are specialized feeders on Pinaceae, particularly Pinus species. Essigella californica, the type species and most well-known member, is native to western North America and has become an invasive pest in Australia and New Zealand, where it affects commercial pine plantations. The genus is characterized by its association with conifer hosts and its potential to cause defoliation and reduced tree growth.
