Semmens, T.D., McQuillan, P.B. & Hayhurst, G. (1992). Catalogue of the Insects of Tasmania. Government of Tasmania: Department of Primary Industry, 104 pp.

TMAG collections

Typical length (mm): 40
Flightedness: winged and assumed capable of flight

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

Ecological attributes: — Eucalyptus obliqua is a host-plant (Bashford, 1990a) — Eucalyptus ovata is a host-plant (Bashford, 1990a) — Eucalyptus sp. is a host-plant (Bashford, 1990a) — Associated with dry brown cubic rot (Harrison, 2007) — Associated with mudguts (Harrison, 2007) — Associated with wet brown cubic rot (Harrison, 2007) — Can inflict significant damage on Eucalyptus spp. (Elliott & deLittle, 1985) — Implicated in the formation of mudguts (Grove, 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: — At light (with use of light-trap) — Emergence trapping from log of Eucalyptus obliqua — Hand collection (substrate not specified) — Not specified — Rearing in insectary (host not documented) — Rearing in insectary from Eucalyptus sieberi.
