Ecological attributes: — Cassinia aculeata is a host-plant (Bashford, 1990a) — Eucalyptus cordata is a host-plant (Bashford, 1990a) — Nothofagus cunninghamii is a host-plant (Bashford, 1990a) — Richea pandanifolia is a host-plant (Bashford, 1990a) — 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 log of Eucalyptus obliqua — Hand collection (substrate not specified) — Knockdown fogging of canopy of Nothofagus cunninghamii — Malaise trapping — Not specified — Pitfall trapping — Rearing in insectary (host not documented).
