Ecology

Assumed larval feeding: detritivore
Association with dead wood or old trees: not saproxylic

Ecological attributes: — 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: — Beating vegetation (species not specified) — Emergence trapping from log of Eucalyptus obliqua — Hand collection from flowers of Eucryphia lucida (Ettershanks & Ettershanks, 1993) — Hand collection from flowers of Eucryphia milliganii (Ettershanks & Ettershanks, 1993) — Knockdown fogging of canopy of Nothofagus cunninghamii — Malaise trapping — Pitfall trapping — Sticky trapping on Eucalyptus obliqua.
