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

Ecological attributes:Eucalyptus obliqua is a host-plant (Bashford, 1990a) — Eucalyptus sieberi is a host-plant (Bashford, 1990a) — Affiliated with older trees (Harrison, 2007) — Associated with brown spongy cubic rot Yee et al., 2006) — Associated with dry brown cubic rot (Harrison, 2007) — Associated with wet brown cubic rot (Harrison, 2007) — Found under large logs (Grove 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: — At light (with use of light-trap) — 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) — Hand collection from under log of Eucalyptus sp. — Log-mounted flight intercept trapping — Panel trapping — Pipe trapping — Pitfall trapping — Vane trapping.
