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

Ecological attributes: — Affiliated with burnt tree-wounds (Harrison, 2007) — 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 log of Eucalyptus obliqua — Hand collection (substrate not specified) — Knockdown fogging of canopy of Eucalyptus obliqua — Knockdown spraying of bark of Eucalyptus obliqua — Pipe trapping — Pitfall trapping — Sticky trapping on Eucalyptus obliqua — Vane trapping.
