Psyllids of North America
Descriptions and Illustrations
Several types of maps are currently available:
State maps provide precise visualization of the recorded ranges of psyllid species, and are most useful for states where heavy surveying and collecting has occurred, such as California or Florida. Conversely, the value of state maps decreases notably for undercollected states; for such states, a regional map (see below) may provide more insight.
As psyllids are relatively understudied and undercollected in many parts of the US, state data maps often present an incomplete picture of a psyllid's true range. Many psyllids are likely to occur throughout the range of their host plant, but state records often do not reflect this (except in states where heavy collecting has occurred). By taking a region-centric approach and dividing the US and Canada into seven geopolitical regions, a better understanding of psyllid distribution may be possible.
Important Pest Map: Asian Citrus Psyllid
The Asian Citrus Psyllid,
Kuwayama, was first detected in the United States in Florida in 1998. The species is notable as a vector of Huanglongbing disease, or Citrus Greening, which is fatal to citrus and potentially very concerning for the citrus industry. This map shows the known range of the species to date.
Additionally, individual maps exist for all species on this site; these maps can be accessed from the individual species pages.
