Phyllocnistis citrella, the citrus leafminer, is a moth of the family Gracillariidae. It is also known as CLM in agriculture. It was described by Henry Tibbats Stainton from India in 1856. It was first found in Florida, United States, in 1993, but is now found all over the world, including Argentina, Australia, Brazil, China, Corsica, Costa Rica, Cuba, India, Israel, Madeira, Malaysia, Mauritius, Mexico, the Philippines, South Africa, Spain, Sri Lanka and other parts of the United States.
The wingspan is about 5 millimetres (0.20 in). The larvae are considered a serious agricultural pest on Citrus species, such as Aegle marmelos, Atalantia, Citrofortunella microcarpa, Citrus limon, Citrus paradisi, Citrus maxima, Fortunella margarita, Murraya paniculata and Poncirus trifoliate. Larvae have also been recorded on Garcinia mangostana, Pongamia pinnata, Alseodaphne semecarpifolia, Loranthus and Jasminum sambac. They mine the leaves of their host plant. The mine consists of a long epidermal corridor with a well-marked central frass line. The mine is mostly lower-surface, but sometimes upper-surface, and rarely on the rind of the developing fruit. Citrus leaf miner larvae are thus protected from many topic insecticide treatments. Pupation takes place in a chamber at the end of the corridor, under an overturned part of the leaf margin.

Rare
Under 5% of wildlife watchers report a Citrus Leafminer sighting in Sydney on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 446th most-seen of the 742 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 a Citrus Leafminer in Sydney on a given day, so our monthly data shows no clear season.
Among the best
Of the 6 cities where we can rate Citrus Leafminer sightings, Sydney ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Melbourne (Australia, under 5%), San Francisco (United States, under 5%) and Los Angeles (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Citrus Leafminer is recorded against all the insects logged in Sydney (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.
