Chrysomya albiceps
In 3 days ~10% in a week ~20%
Chrysomya albiceps is a species belonging to the blow fly family, Calliphoridae. Chrysomya albiceps is considered conspecific with Chrysomya rufifacies by some authorities. The two species have a similar biology and the morphological differences are slight (prostigmatic bristle present in C. albiceps absent in C. rufifacies (but not all rufifacies so this character is unreliable)).There are minor differences in larval morphology. The taxonomy of C. rufifacies is therefore not completely clear, and its relation to C. albiceps has not been fully determined.
This species was originally spread in the African continent, southern Europe and Asia. From the seventies it began to spread also in neo-tropical regions such as Colombia, Argentina, Peru and Paraguay. It is a very common species in the Mediterranean regions, and it is present in Egypt, Iran, Iraq, Kuwait, Lebanon, Libya, Oman, Pakistan, Kingdom of Saudi Arabia, Syria, United Arab Emirates and Turkey.
C. albiceps is a subtropical to temperate species. It is present at altitudes of 200–1,000 metres (660–3,280 ft), but it is more abundant at an elevation of 1,000–3,100 metres (3,300–10... Wikipedia →

Rare
Under 5% of wildlife watchers report a Banded Blowfly sighting in Barcelona on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 336th most-seen of the 381 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.
August and October–November
In those months about 10% of wildlife watchers report a Banded Blowfly in Barcelona on a given day, against under 5% in September and December–July, the lowest months.
4th of 5
Of the 5 cities where we can rate Banded Blowfly sightings, Barcelona ranks 4th at under 5%. The best odds are in Athens (Greece, about 10%), Santiago (Chile, about 10%) and Lima (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Banded Blowfly is recorded against all the insects logged in Barcelona (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.
