TMAG collections
Classification
Order: Coleoptera
Suborder: Polyphaga
Superfamily: Curculionoidea
Family: Curculionidae
Subfamily: Molytiinae
Tribe: Phrynixini
Morphology
Typical length (mm): 12
Flightedness: (not yet documented)
Ecology
Assumed larval feeding: wood-feeder
Association with dead wood or old trees: obligately saproxylic
Ecological attributes: — Affiliated with larger-diameter logs in mature (unlogged) forest (Yee, 2005) — Affliliated with mature (unlogged) forest (Baker et al., 2009c) — Associated with fibrous surface rot (Yee et al., 2006) — May occupy logs or trunks of Eucalyptus obliqua, at least temporarily, since found having emerged within a year of felling (Grove & Bashford, 2003) — May occupy logs or trunks of Eucalyptus obliqua, at least temporarily, since found having emerged within six years of felling (Grove et al., 2009).
Collection method(s) for TMAG material: — Emergence trapping from log of Eucalyptus obliqua — Hand collection (substrate not specified) — Pitfall trapping.
