Myzus persicae
In 3 days ~10%
Myzus persicae, known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops.
Originally described by Swiss entomologist Johann Heinrich Sulzer in 1776, its specific name is derived from the Latin genitive persicae, "of the peach". The syntype specimen of this species is located in the Illinois Natural History Survey Insect Collection.
Life cycle of the green peach aphid varies depending on temperature. A fully completed generation takes approximately 10 to 12 days with over 20 annual generations reported in mild climates. Aphids overwinter on Prunus plants and once plants break their dormancy, the eggs hatch and nymphs feed on the flowers, young foliage and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green Peach Aphid sighting in Los Angeles on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 715th 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 Green Peach 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 Green Peach 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 Green Peach Aphid is recorded against all the insects logged in Los Angeles (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.
