Anaglyptus (Aglaophis) colobotheoides, a species occuring in North-East Asia (Russian Far East, Japan, Korea, China), has been described as Aglaophis colobotheoides from Sapporo environs by Henry Walter Bates in 1884 [❖]. The species is ecologically associated with deciduos forests, larvae develop in dead/dying wood of deciduous trees (in Russian Far east in Maakia, Αcer, Padus, Prunus, Fraxinus). Larvae feed in upper layer of sapwood, make longitudinal, often meandering galleries, and fill them compactly with frass. Larvae create shallow (in depth 2-7 mm) pupal cells longitudinal to trunk, prepare outlet to surface of trunk and pupate. The first winter of the 2-year developmental cycle overwinter larvae, the second one freshly hatched adults. Emergence of beetles from mid-May to July (peak in June), adults can be found on the host trees and occasionally visit also flowers [✧].

Body length:	11 - 14 mm
Life cycle:	2 years
Adults in:	May - July
Host plant:	polyphagous in deciduous trees (Maakia, Αcer, Padus, Prunus, Fraxinus etc.)
Distribution:	Russian Far East, Japan, Korea, NE China

The depicted female beetle was collected at Kamenystyi (Каменистый) creek / Listvennichnaya (Лиственничная) river (N43°34′25″ E131°18′53″; 500-550 m a.s.l, Borisovskoye Plateau, South of Primorsky krai, Far Eastern Federal District, Russia) on May 29, 2019.
