In 3 days ~10% in a week ~20%
Ptilothrix bombiformis, known generally as the hibiscus bee or eastern digger bee, is a species of solitary chimney bee in the family Apidae. It is found in the eastern United States and, rarely, in southern Ontario, Canada.
The hibiscus bee has a large, rounded body similar to a bumblebee, earning it the species epithet bombiformis (bumblebee-shaped). The hibiscus bee has yellow hairs on its head, mesosoma, and on the first segment of the metasoma. The remaining segments of the metasoma are black. Both males and females have very long, hairy legs, but the hind legs of the female are visibly hairier, as they have plumose branched hairs for transporting pollen and water to the nest.
The hibiscus bee has three main habitat requirements: the presence of Hibiscus flowers, water, and an area of hard-packed, dried mud ground in which to nest. Typically, these requirements are all met in a marshy area suitable for Hibiscus plants (commonly called hibiscus or mallows). However, these adaptable bees also use human-altered landscapes, finding pollen in hibiscus landscaping plants, nesting sites on dirt roads and levees, and sources of water such as puddles created...

GBIF citizen-science records
It is estimated from how often the Hibiscus Turret Bee is recorded against all the insects logged in Philadelphia (8 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.
