The andromeda lace bug (Stephanitis takeyai) is a pest insect on plants of the genus Pieris, especially Pieris japonica, the Japanese andromeda. It originated in Japan with its host plant but has since been introduced to other areas of the globe. At least one Pieris species, Pieris floribunda, is resistant to the lace bug.
The andromeda lace bug is about 3 millimeters in length. It has a characteristic rounded pronotum, lacy black and white wings, and shiny gold highlighting. The bug produces mottling on the leaves of the plant, and heavy infestations can cause the leaves to drop in large numbers, stunting the plant's growth. Both nymph and adult forms damage the leaves by piercing them to suck the juices, and leave dark frass on the undersides of the leaves. Damage is worst on plants that grow in full sun. Wikipedia →

Rare
Under 5% of wildlife watchers report an Andromeda Lace Bug sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Andromeda Lace Bug in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 11 cities where we can rate Andromeda Lace Bug sightings, London ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Manchester (United Kingdom, under 5%), Leeds (United Kingdom, under 5%) and Birmingham (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Andromeda Lace Bug is recorded against all the insects logged in London (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.
