Locally abundant in weedy areas near woodlands throughout temperate North America east of the Rocky Mountains (Doering 1922). Hosts. Nymphs feed on the aerial parts of many different plants, including trees, broad-leaved herbaceous plants, brambles, and grasses; 60 different hosts are recorded for this species (Doering 1942), and this is probably a partial list. Adults feed on the same hosts as the nymphs (Doering 1922)' Lepyronia lLepyronialcoleoptrata
