Zopherus nodulosus
In 3 days ~10% in a week ~30%
Zopherus nodulosus is a species of ironclad beetle in the family Zopheridae. It is found in Central America and North America. It can grow between 1.5 and 2 centimetres in length. The body is a blotchy black-and-white pattern, and the legs are fully black. The subspecies name, haldemani, references the Haldeman brothers, Samuel Haldeman and Horace Haldeman, the former a naturalist and philologist, the latter a soldier and one of the first people to concentrate on insect collection in Texas.
They are thought to feed on lichen and dead plant material. Females have been observed laying eggs on American elms, and larvae and pupae have been found in pecan wood, which "apparently serves as the developmental site for this species". They are found in East and Central Texas.
Z. n. nodulosus can grow between 1.4 and 2.8 centimetres in length, and 0.5 to 1.1 cm in width. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Zopherus nodulosus is recorded against all the insects logged in San Antonio (52 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.
