TMAG collections

Classification
Order: Coleoptera

Suborder: Polyphaga

Superfamily: Scarabaeoidea

Family: Scarabaeidae

Subfamily: Melolonthinae

Tribe: Heteronycini

Morphology
Typical length (mm): 15
Flightedness: winged and assumed capable of flight
Ecology
Assumed larval feeding: root-feeder, perhaps in association with rotting wood
Association with dead wood or old trees: at least facultatively saproxylic

Ecological attributes: — 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 cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Flight intercept trapping (trough below Malaise trap) — Hand collection (substrate not specified) — Malaise trapping — Pipe trapping — Pitfall trapping.
