Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug now in the taxonomic family Liviidae. It is one of two confirmed vectors of citrus greening disease. It has a wide distribution in southern Asia and has spread to other citrus growing regions.
The Asian citrus psyllid originated in Asia but it is now also found in parts of the Middle East, South and Central America, Mexico, and the Caribbean. In the United States, the psyllid was first detected in Florida in 1998 and is now also found in Louisiana, Georgia, Arizona, South Carolina, Texas, and since 2003 in California. In Southern California, the San Joaquin Valley, and Central Coast counties, such as San Luis Obispo, an eradication program has been instituted in an attempt to prevent it from becoming established. In the whole of the United States and its territories, areas where this psyllid are found are under quarantine restrictions.
The adult psyllid is about four millimetres long with a fawn and brown mottled body and a light brown head. It is covered with a whitish, waxy secretion which makes it look dusty. The forewings are broadest at the back and have a dark edging... Wikipedia →

Rare
Under 5% of wildlife watchers report an Asian Citrus Psyllid sighting in Monterrey on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 196th most-seen of the 413 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January–March and October
In those months about 10% of wildlife watchers report an Asian Citrus Psyllid in Monterrey on a given day, against under 5% in April–September and November–December, the lowest months. Those are among Monterrey's driest months, with about 35 mm of rain a month against 200 mm in September.
3rd of 7
Of the 7 cities where we can rate Asian Citrus Psyllid sightings, Monterrey ranks 3rd at under 5%. The best odds are in Kaohsiung (Taiwan, about 20%) and San Pedro Sula (Honduras, about 10%).
Same order: Hemiptera
The closest relatives of the Asian Citrus Psyllid that you can see in Monterrey (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Red-Shouldered Bug (about 10%), Acanthocephala alata (about 10%) and Prosapia simulans (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Asian Citrus Psyllid is recorded against all the insects logged in Monterrey (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
