Ecology
Assumed larval feeding: (not yet documented)
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: — Baited trapping (funnel trap) — Emergence trapping from cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Hand collection (substrate not specified) — Knockdown fogging of canopy of Nothofagus cunninghamii — Malaise trapping — Sticky trapping on Acacia dealbata — Sticky trapping on Acacia melanoxylon — Sticky trapping on Eucalyptus obliqua — Sticky trapping on Eucalyptus viminalis — Trapping using a range of devices placed in crown of Eucalyptus obliqua (Bar-Ness, 2005) — Trunk window trapping (Harrison, 2007).
