It has also been known as Crocisa australensis and Crocisa lamprosoma. In the late 1950s to early 1960s, these names were synonymized by Dutch entomologist Maurits Lieftinck, who undertook a broad revision of the genus, and gave this species the current name of Thyreus caeruleopunctatus. The specific name (caeruleopunctatus) means "sky-blue spotted" in Latin.

With luck
About 10% of wildlife watchers report a Chequered Cuckoo Bee sighting in Melbourne on a given day, based on 107 verified sightings from GBIF citizen-science data. It is the 146th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
December to April
In those months about 10% of wildlife watchers report a Chequered Cuckoo Bee in Melbourne on a given day, against under 5% in May to November, the lowest months.
Yes
Of the 3 cities where we can rate Chequered Cuckoo Bee sightings, Melbourne has the highest daily chance: about 10%. Next come Sydney (Australia, under 5%) and Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Chequered Cuckoo Bee is recorded against all the insects logged in Melbourne (107 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.
