Ecology

Assumed larval feeding: wood-feeder
Association with dead wood or old trees: obligately 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: — Baited trapping (funnel trap) — Emergence trapping from log of Eucalyptus obliqua — Hand collection (substrate not specified) — Hand collection from flowers of Eucryphia lucida (Ettershanks & Ettershanks, 1993) — Hand collection from flowers of Helichrysum purpurascens (Ettershanks & Ettershanks, 1993) — Hand collection from flowers of Leptospermum sp. (Ettershanks & Ettershanks, 1993) — Malaise trapping — Not specified — Pipe trapping — Pitfall trapping — Sticky trapping on Eucalyptus obliqua.
