Poecilocapsus lineatus, commonly known as the fourlined plant bug, is a species of true bug (Hemiptera) in the family Miridae. This species is native to the United States and Canada. The adults are about 7–7.5 millimetres (0.28–0.30 in) in length and 3.5 millimetres (0.14 in) in width. Adults have four distinct black lines against a background color ranging from green to yellow, with an orange head and prominent, dark red eyes. Nymphs grow rapidly through five instars, with wing pads growing at each molt. Nymphs are a bright red color with black markings, except for the last instar which is bright orange.
This species has a wide host range, but shows strong preference for plants in the mint and composite families (Lamiaceae and Asteraceae). Various herbaceous perennials and shrubs in these families are favored for reproduction and account for the majority of damage observed in the landscape and garden, although vegetables are also sometimes damaged. Both nymphs and adults feed on leaves creating the water-soaked patches of leaf tissues that may later dry up or fall out to produce tiny holes.

Among the best
Of the 12 cities where we can rate Four-Lined Plant Bug sightings, Toronto ranks 7th at about 10%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, about 10%), Detroit (United States, about 10%) and Austin (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Four-Lined Plant Bug is recorded against all the insects logged in Toronto (170 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.
