TMAG collecctions

Classification

Order: Coleoptera

Suborder: Polyphaga

Superfamily: Curculionoidea

Family: Curculionidae

Subfamily: Molytinae

Tribe: Cryptorhynchini

Morphology

Typical length (mm): 11
Flightedness: functionally flightless

Ecology

Assumed larval feeding: wood-feeder
Association with dead wood or old trees: obligately saproxylic

Ecological attributes: — Affiliated with older trees (Harrison, 2007) — 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 (substrate not specified) — Emergence trapping from cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Flight intercept trapping (trough below Malaise trap) — Hand collection (substrate not specified) — Hand collection from under bark (tree species not specified) — Knockdown fogging of canopy of Acacia melanoxylon — Knockdown fogging of canopy of Eucalyptus obliqua — Knockdown fogging of canopy of Nothofagus cunninghamii — Log-mounted flight intercept trapping — Malaise trapping — Pitfall trapping.
