Pseudaulacaspis pentagona
In 3 days ~10% in a week ~30%
Pseudaulacaspis pentagona, the white peach scale or mulberry scale, is a species of armoured scale insect in the family Diaspididae. This scale infests over 100 different genera of plants including many fruit trees and ornamentals.
The adult female insect is up to 2.5 mm (0.10 in) in length. The soft yellow body is concealed under a roughly circular, whitish test with a yellowish-brown off-centre spot (this is the exuviae or shed skins of the last two nymphal moults). Males are concealed under whitish, felted, elongated oval tests with yellowish spots at one end; sometimes many males will accumulate in one area, covering the bark and looking like snow. Mature males have no mouthparts but have wings and seek out females, while mature females do not have wings and remain permanently in one place.
Pseudaulacaspis pentagona is native to eastern Asia but has been accidentally introduced into many other warm and temperate parts of the world. In Europe, it was first detected in Italy in the nineteenth century and is now additionally found in Azerbaijan, Bulgaria, France, Georgia, Germany, Greece, Hungary, Macedonia, Malta, Montenegro, Netherlands, Portugal...

Rare
Under 5% of wildlife watchers report a White Peach Scale sighting in Lima on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 81st most-seen of the 95 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.
February–March, May, July and September–October
In those months about 10% of wildlife watchers report a White Peach Scale in Lima on a given day, against under 5% in April, June, August and November–January, the lowest months.
Only Lima, in our data
Lima is the only city on Wallace's Line with enough records to rate White Peach Scale sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Diaspididae
The closest relatives of the White Peach Scale that you can see in Lima (family Diaspididae, Armored Scale Insects) are Rose Scale (about 10%), Purple Scale (about 10%) and Black Thread Scale (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White Peach Scale is recorded against all the insects logged in Lima (6 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.
