Dryophthorus ECZ sp 01 (a species of weevil)

TMAG collections

Typical length (mm): 3
Flightedness: winged and assumed capable of flight

Morphology (characterised by L. Forster): — Elytra with ridges which are the same height between all rows of punctures; evenly rounded apically (when viewed dorsally) — Eyes usually narrowly elliptical, with dark edges — Wings present.

Source literature on morphology and taxonomy (*primary taxonomic source, where identified):

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

Ecological attributes: — Associated with fibrous surface rot (Yee et al., 2006) — Associated with mudguts (Yee et al., 2006) — Associated with red-brown blocky muddy rock (Yee et al., 2001) — 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) — Trunk window trapping (Harrison, 2007).
