Pedostrangalia femoralis, an East-Palaearctic forest belt species occuring in Russia (East Siberia and Far East), North China, Japan, and Korea, has been described from "Daourie" (Amur region, Russian Far East) as Stenura femoralis by Victor Ivanovitsch Motschulsky in 1860 [✧]. The species is ecologically associated with Manchurian striped maple (Acer tegmentosum), Ussuri pear (Pyrus ussuriensis), and other deciduous trees. P. femoralis larvae develop in decaying and even rotten wood, some larvae have been found at the base of dead branches on living trees [probably similar biology to West-Palaearctic Pedostrangalia revestita (Linnaeus, 1767)], but dead trees are also colonized. Pupation in wood after the second overwintering during spring and early summer. Life-cycle 2 years. Adults, active from June to August, are diurnal and anthophilous [❖][✩].

Body length:♂♂ 10 - 14 mm / ♀♀ 11 - 15 mm
Life cycle:2 years
Adults in:May - August
Host plant:polyphagous in deciduous trees (Acer, Pyrus, Ulmus, Sorbus, etc.)
Distribution:Russia (East Siberia and Far East), North China, Japan, and Korea

The depicted mounted beetles (♂/♀ - 13 mm) were collected in the right side of the Severyanka (Северянка) river valley (N44°20′18″ E146°00′42″; 20-40 m a.s.l., Kurils Nature Reserve, Kunashir/Кунаши́р island, Kuril Islands, Yuzhno-Kurilsky district, Sakhalin region, Russia) on July 28, 2013.
