In 3 days ~10% in a week ~20%
Compsocerus violaceus is a species of beetle in the family Cerambycidae. It occurs in South America, being common in southern Brazil, northern Argentina and Uruguay. Compsocerus violaceus is considered an agricultural pest, attacking several cultivated tree species, such as acacias, eucalypts, willows, fig trees, citrus trees and peach trees. Eggs are laid on tree trunks, usually inside small fissures in the bark. After eclosion, the larvae build a gallery below the bark in branches with diameters between two and six cm and start to feed on the wood, taking about ten months to become adults. Adults have been reported to feed on fruits, flowers, and sap leaking from injured tree trunks.

GBIF citizen-science records
It is estimated from how often the Compsocerus violaceus is recorded against all the insects logged in São Paulo (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.
