Neoclytus caprea
In 3 days ~10% in a week ~20%
Neoclytus caprea, commonly known as the banded ash borer, is a species of beetle in the family Cerambycidae. It feeds on the sapwood of ash, oak, and hickory. It often emerges indoors from firewood; logs may become infested within 20 days of felling in summer. The banded ash borer exhibits sexual dimorphism, as the female is considerably larger than the male and has yellow and black elytra coloring rather than the male's white and black coloring. It produces one generation a year.
The flight period of the banded ash borer, which is triggered by seasonal phenological mechanisms, prevents the species from being cross-attracted to sympatric species with similar or identical pheromone chemical compositions. N. caprea emerges and flies from its host species in early spring, much earlier than species that possess 3R-ketol compounds in their chemical composition, resulting in negligible overlap between flight periods of sympatric species. This effectively isolates the banded ash borer, preventing the possibility of cross attraction.
Neoclytus caprea is identified colloquially by the name banded ash borer in reference to one of its common host plants, the ash tree, which... Wikipedia →

Rare
Under 5% of wildlife watchers report a Banded Ash Borer sighting in Salt Lake City on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 242 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March and April
In those months about 10% of wildlife watchers report a Banded Ash Borer in Salt Lake City on a given day, against under 5% in May to February, the lowest months.
Only Salt Lake City, in our data
Salt Lake City is the only city on Wallace's Line with enough records to rate Banded Ash Borer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Banded Ash Borer is recorded against all the insects logged in Salt Lake City (5 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.
