Ceratitis capitata
In 3 days ~10% in a week ~30%
Ceratitis capitata, commonly known as the Mediterranean fruit fly or medfly, is a yellow-and-brown fly native to sub-Saharan Africa. It has no near relatives in the Western Hemisphere and is considered to be one of the most destructive fruit pests in the world. There have been occasional medfly infestations in California, Florida, and Texas that require extensive eradication efforts to prevent the fly from establishing itself in the United States.
C. capitata is the most economically important fruit fly species because of both its ability to survive cooler climates more successfully than most other fruit fly species and its ability to inhabit more than 200 tropical fruits and vegetables to which it causes severe destruction and degradation. The practices that are used to eradicate the medfly after its introduction into a new environment can be extremely difficult and expensive, but infestation of C. capitata lowers crop yields and induces costly sorting processes for fresh fruits and vegetables.
C. capitata eggs are characterized by their curved shape, shiny white color, and smooth features. Each egg is approximately 1 millimetre (5⁄128 in) in length... Wikipedia →

Rare
Under 5% of wildlife watchers report a Mediterranean Fruit Fly sighting in Perth on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 275 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.
May, July, September and December–January
In those months about 10% of wildlife watchers report a Mediterranean Fruit Fly in Perth on a given day, against under 5% in February–April, June, August and October–November, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Mediterranean Fruit Fly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
8th of 18
Of the 18 cities where we can rate Mediterranean Fruit Fly sightings, Perth ranks 8th at under 5%. The best odds are in Mendoza (Argentina, about 20%), Valencia (Spain, about 10%) and Los Angeles (United States, about 10%).
Same order: Diptera
The closest relatives of the Mediterranean Fruit Fly that you can see in Perth (order Diptera, Flies) are Yellow-Shouldered Stout Hover Fly (about 10%), Australian Tiger Crane Fly (about 10%) and Bathroom Moth Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mediterranean Fruit Fly is recorded against all the insects logged in Perth (13 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.
