Check-list of North American Aphids

Plant lice of North America: USA, Canada, Mexico & Greenland

Brightwell, R. & Dransfield, R.D.

Draft list. Revised June 2020

Aphidoidea, known as aphids, or to Americans as 'plant lice', are species of small, pear-shaped, soft bodied, sap-feeding, insects. Roughly 1500 Aphidoidea species have been recorded in North America, or more specifically, from the Nearctic eco-geographical region. The Nearctic region includes most of North America (the USA, Canada, Greenland, and parts of Mexico).

Simply listing those aphids is not quite as simple as might be supposed: New species are discovered, new arrivals are noted (few of which prosper), errors in old reports are found, and the species names and classifications get amended. This list is compiled from the most current worldwide aphid identification guide (Blackman & Eastop, 2016) and the checklist of the Hemiptera of Canada and Alaska (Maw et al., 2006). We include English names, and some synonyms (for a fuller list see Favret, 2016), as well as noting which species are not native, when their status is uncertain, or if they have been recorded erroneously. We also include non-native (adventive) aphids detailed in Footit et al. (2006), Skvarla et al. (2017) and other sources.

To facilitate searches, species include their binary, Genus species, name.

Some entries are highlighted as follows:

Turquoise   Not native. Yellow   Status uncertain. Red   Recorded erroneously in some lists. Underlined species   Link to their InfluentialPoints Gallery page
