Chilacis typhae, the bulrush bug, is a species of true bug in the family Artheneidae. It is found in Europe and Northern Asia (excluding China) and North America. It is typically associated with greater reedmace and Typha angustifolia; adults can be found pairing on the seed heads between spring and autumn. They often overwinter within the seed heads. At times, they can occur at significant concentrations, with over 1000 individuals found in a single seedhead. Wikipedia →

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