Aleuroplatus coronata, the crown whitefly, is a species of whitefly in the family Aleyrodidae. It is native to the southern United States and Mexico, and it is now established in California, where it is associated with oak and chestnut trees.

They have four white wings, which appear covered in a dusty wax, and somewhat resemble the wings of a small moth. The adult lays cigar-shaped eggs, which hatch into nymphs, with small, elliptical, semitransparent bodies and antennae, legs, and hairs extending laterally from their margins. The nymphs lose their legs in their second instar, attach themselves to the underside of leaves, and remain immobile into the pupal stage. The pupae are enclosed in puparium, or the exoskeleton of the final larval instar. The puparium is surrounded by a characteristic crown of waxy filaments or plates, inspiring the common name, crown whitefly.
Aleuroplatus coronata consumes sap from its hosts, and favors coast live oak in particular. Although heavy infestations may cause leaves to fall, the whitefly does not otherwise significantly... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Crown Whitefly is recorded against all the insects logged in San Diego (11 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.
