Tamarixia radiata, the Asian citrus psyllid parasitoid, is a parasitoid wasp from the family Eulophidae which was discovered in the 1920s in the area of northwestern India (Punjab), now Pakistan. It is a parasitoid of the Asian citrus psyllid (Diaphorina citri), an economically important pest of citrus crops around the world and a vector for Citrus greening disease.
The adults of Tamarixia radiata are small, 0.92 to 1.04 mm long, black wasps. They have widely separated eyes, which are red in newly emerged adults, on a head which is slightly wider than its length, and transparent wings with pale yellow veins. There is marked sexual dimorphism, with the male antennae being one and a half times the length of female antennae. The antennae of the males have long and slightly curved setae while female antennae have short setae. The males are also slightly smaller than females in length and have smaller wings and darker abdomens. On the females, the ovipositor barely protrudes. In both males and females the head and thorax are shiny black and the posterior dorsal and lateral portions of the gastric segments are black and the vent and a patch on the anterior dorsal gaster...

Rare
Under 5% of wildlife watchers report a Tamarixia radiata sighting in Kaohsiung on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 201st most-seen of the 218 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 and October
In those months about 10% of wildlife watchers report a Tamarixia radiata in Kaohsiung on a given day, against under 5% in March–September and November–January, the lowest months. Those are among Kaohsiung's driest months, with about 50 mm of rain a month against 440 mm in August.
Only Kaohsiung, in our data
Kaohsiung is the only city on Wallace's Line with enough records to rate Tamarixia radiata sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hymenoptera
The closest relatives of the Tamarixia radiata that you can see in Kaohsiung (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Asian Honey Bee (about 20%), Red Dwarf Honey Bee (about 20%) and Delta pyriforme (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tamarixia radiata is recorded against all the insects logged in Kaohsiung (5 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.
