In 3 days ~10%
Compsomyiops callipes, previously known as Paraluclia wheeleri, is a member of the blowfly family Calliphoridae. It is a warm weather fly that can be found in southwestern parts of the United States and parts of South America. This species can be identified by its chaetotaxy, metallic blue color, club-shaped palp, and brown calypters.
Compsomyiops callipes serves an important role in the field of medicocriminal entomology, a subfield of forensic entomology, by determining post mortem intervals (PMI). This species is attracted to carrion and has been involved in case studies in California where it has been the primary fly found on human remains.
Compsomyiops callipes was first described in 1877. It was later described as Paralucilia wheeleri but it was not recognized that this was only a new name for a species that had already been named. In 1985, J. P. Dear revised the New World tribe Chrysomyini, which resulted in Paralucilia wheeleri being synonymized under Compsomyiops callipes Bigot. It is a member of the family Calliphoridae, commonly called blowflies, and the subfamily Chrysomyinae.

Rare
Under 5% of wildlife watchers report a Compsomyiops callipes sighting in San Francisco on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 518th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Compsomyiops callipes in San Francisco on a given day, so our monthly data shows no clear season.
Only San Francisco, in our data
San Francisco is the only city on Wallace's Line with enough records to rate Compsomyiops callipes sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Compsomyiops callipes is recorded against all the insects logged in San Francisco (10 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.
