Dactylopius opuntiae, also known as the prickly pear cochineal, is a species of scale insect in the family Dactylopiidae. Dactylopius opuntiae was first identified by Cockerell as Coccus cacti opuntiae after he collected it from cactus plants in Mexico in 1896. Later, it was considered a synonym of Dactylopius tomentosus, and workers often referred to the same species by different names or used the same name for different species. De Lotto notes that it became common practice to call Dactylopius opuntiae a distinct wild cochineal insect from Dactylopius tomentosus, even though their identity and status were never fully resolved. Eventually, in 1929, the species was classified as Dactylopius opuntiae by Cockerell.
All species of the family Dactylopiidae have females with an oval-shaped body that is purple-red in color and covered in a white, cotton-like wax. This wax protects the body of the cochineal from heat, cold, and predators. Adult females are sessile and form colonies of up to a few thousand individuals of mixed age, creating conspicuous clusters of white wax all over the plant. Adult females of Dactylopius opuntiae produce red glucosidal hydroxyanthrapurin... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cactus Scattered Cochineal is recorded against all the insects logged in Los Angeles (5 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.
