Crioceris duodecimpunctata or the spotted asparagus beetle is a species of shining leaf beetle belonging to the family Chrysomelidae, subfamily Criocerinae. The length of beetles varies from 5 to 6.5 millimeters. The colour of head, pronotum and elytra is reddish orange, while the scutellum is black. On the elytra there are twelve black dots.
It feeds on Cucurbitaceae and asparagus species. The larvae feed only on the asparagus berries, being the second most important pest of this plant, while adults prefer tender shoots and leaves. They are found in the whole Palearctic realm, including the British Isles. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Spotted Asparagus Beetle is recorded against all the insects logged in Edmonton (6 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.
