Xylocopa caffra
In 3 days ~40% in a week ~70%
Xylocopa caffra is a species of Afrotropical carpenter bee that ranges from west to central and southern Africa, besides Madagascar and some Indian Ocean archipelagos. The females are black with two white or yellow bands over the hind thorax and first abdominal segment respectively, while the males are uniform greenish yellow in colour. Females with white bands are associated with dry climatic conditions during larval development, but females of either colour, or colour grade, may emerge from the same brood. In the Western Cape all have yellow bands however. A form with orange-red bands occurs in East Africa.
The species is at home in various habitat types, from moist coastal settings to dry savannah. The territorial males patrol small areas around particular plants or flowers. The females are solitary nesters in Aloe or Agave stems, tree branches or timber. The nests are partitioned into various cells, separated by walls of glued wood residue. A wide variety of plants are used as sources of nectar and pollen.
As with other carpenter bees, the larvae are fed a mixture of pollen and nectar. The females have a mutualistic association with phoretic mites... Wikipedia →

It is the 20th most-seen of the 274 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Double-Banded Carpenter Bee in Pretoria on a given day, against under 5% in June, the lowest month.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Double-Banded Carpenter Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best

GBIF citizen-science records
It is estimated from how often the Double-Banded Carpenter Bee is recorded against all the insects logged in Pretoria (51 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.
