Common Name: Narrow-collared Snail-eating Beetle
Synonyms: Cychrus angusticollis Fischer von Waldheim, 1823; Pemphus angusticollis nigripennis Roeschke, 1907, Scaphinotus angusticollis olympiae Van Dyke, 1944
Macrohabitat: Lowlands to midlands, subalpine zone, sea level- 1387 meters altitude, in forests (coniferous, mixed, and deciduous), and cultivated fields. Microhabitat: Shaded moist ground often along streams. Dispersal abilites: brachypterous, hence flightless, thus vagility limited to walking or running. Seasonal occurance: Adults have been found in March-November. Teneral adults in May-July, and September. Behavior: Nocturnal, gregarious (up to 50 individuals in or under a single log). Adults are predaceous on snails, slugs, earthworms, and spiders. Taking cover during the day mostly in rotten fallen trees and tree-stumps, under the loose bark and moss of dead standing and fallen trees, in hollow tree roots, also under fallen trees and boards, among dead leaves with other debris. Frequent climber on shrubs, tree-stumps, and fallen trees up to 20 m above ground while foraging. Adults have been found over wintering in old tree-stumps and fallen trees. Sometimes found in and around human settlements. (Erwin, 2001; Gidaspow, 1973; Larochelle & Lariviere, 2003; Data from NMNH, UASM collections)
