Ecology

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

Ecological attributes:Nothofagus cunninghamii is a host-plant (Bashford, 1990a) — 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 TFIC material: — Emergence trapping from cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Hand collection (substrate not specified) — Pitfall trapping — Sticky trapping (substrate not specified) — Sticky trapping on Eucalyptus obliqua — Vane trapping.
