In 3 days ~10%
Aphis spiraecola is a species of aphid described in 1914 by Edith Marion Patch. Its common names include green citrus aphid, Spirea aphid, and apple aphid. It is distributed worldwide, and is most abundant in the United States. It has a diploid chromosome number of 2n=8.
This species was first discovered by Edith Marion Patch in 1914. Patch discovered that A. pomi would feed and develop on Spiraea and A. spiraecola would feed and develop on Malus which confirmed that aphids were a highly variable species. Patch's colonies on apple were decimated by a fungus so all transfer attempts to secondary hosts, which would have demonstrated the limited host range of A. pomi, were made using A. spiraecola from Spiraea instead. Later she suggested using the names A. pomi and A. spiraecola on the basis of the plants on which they were found thus leading to the names each species is known by today. Another species, A. citricola was described by van der Goot in 1912 while doing a study in Chile. This aphid became a synonym for another citrus aphid - Toxoptera citricida. In 1975, Hille Ris Lambers demonstrated that A. citricola referred to A. spiraecola, thus synonymizing A. citricola... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spiraea Aphid sighting in Los Angeles on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 665th most-seen of the 851 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spiraea Aphid in Los Angeles on a given day, so our monthly data shows no clear season.
Only Los Angeles, in our data
Los Angeles is the only city on Wallace's Line with enough records to rate Spiraea Aphid sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spiraea Aphid is recorded against all the insects logged in Los Angeles (7 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.
