Pine shield bug
Chlorochroa pinicola
The pine shield bug (Chlorochroa pinicola) is a species of true bug belonging to the stink bug family (Pentatomidae), found across Europe, including Poland, where it is considered relatively uncommon. Its oval body measures between 11 and 14 mm in length. The dorsal coloration is typically olive-green to brownish (especially in autumn), featuring distinct pale yellowish-white margins along the pronotum and abdomen, as well as a white-tipped scutellum. Its antennae are entirely black, and it possesses an exceptionally long rostrum. This species is closely associated with coniferous trees, primarily Scots pine (Pinus sylvestris), and occasionally spruce or fir. Both nymphs and adults are phytophagous, feeding on sap from pine needles, young buds, and seeds inside cones. The pine shield bug is active from spring until late autumn and overwinters as an adult hidden in forest litter or beneath tree bark.
