Like many other Ground Bugs Lygus pratensis is a loving character. The yellow markings near the top of the wings are often shaped like a heart. It is the most common species of this genus and wide spread all over Europe, Northern Africa, the Middle East, Northern India, China and Siberia. In Britain single brooded, on the continent double brooded in Central and Southern parts. More common in high growing herbs and other medium sized plants than in trees. The adults appear in late summer and autumn and overwinter. They are able flyers and may fly great distances to find good places to spend winter: in straw or mosses or under loose bark. The animal is quite variable, especially in colour. It may be rather greenish, but sometimes it is all brown. This species comes to light at night and is often caught by moth collectors in light traps.
