The horehound bug (Agonoscelis rutila) is a stink bug which sucks the sap of the horehound plant, causing wilting of new shoots. They have five nymphal stages in their development. Although they usually attack horehound, they may also swarm on a variety of other trees and shrubs. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Horehound Bug is recorded against all the insects logged in Sydney (71 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.
