TMAG collections
Classification
Order: Coleoptera
Suborder: Polyphaga
Superfamily: Curculionoidea
Family: Curculionidae
Subfamily: Molytinae
Tribe: Cryptorhynchini
Morphology
Typical length (mm): 4
Flightedness: (not yet documented)
Ecology
Assumed larval feeding: wood-feeder
Association with dead wood or old trees: obligately saproxylic
Ecological attributes: — Affliliated with mature (unlogged) forest (Baker et al., 2009c) — 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 cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Extraction by Berlese funnel from leaf litter — Hand collection (substrate not specified) — Log-mounted flight intercept trapping — Pitfall trapping.
