Thyreus waroonensis, the Waroona cuckoo bee, is a species of bee in the family Apidae. It was described by Theodore D. A. Cockerell in 1913. The body is 8–12 mm long, and the dorsal side is black with white hair spots. The species occurs across a large part of mainland Australia. It is a kleptoparasite, using bees from the Amegilla genus as hosts.
The Waroona cuckoo bee was first described by American entomologist Theodore D. A. Cockerell, who named it Crocisa waroonensis in 1913. He named it after the town of Waroona in Western Australia, which is where the holotype was found. The species was re-described as Thyreus waroonensis by Dutch entomologist Maurits Lieftinck in 1962.
The body is 8–12 mm long and the forewings are 7.5–10 mm long. The dorsal side is black with white hair spots. The forewings are translucent near the body and smoky black over the distal half. The hindwings are mostly translucent, but gradually darkening over the tips.
The overall appearance is similar to T. caeruleopunctatus, but T. waroonensis has longer and more slender antennae. This species occurs across a large part of mainland Australia, and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Waroona Cuckoo Bee sighting in Perth on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 137th 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.
November to January
In those months about 10% of wildlife watchers report a Waroona Cuckoo Bee in Perth on a given day, against under 5% in February to October, the lowest months. Those are among Perth's driest months, with about 20 mm of rain a month against 130 mm in July.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Waroona Cuckoo Bee sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Waroona Cuckoo Bee 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.
