Anilara obscura  Distinctive features

Red-brown to grey-brown, with a moderately short pronotum that is only gently contracted near the base. On the ventral side between the metacoxae males have a weak boss that is not usually darkened and is obtusely angled at is anterior end.

Notes

An extremely abundant and widely distributed species that often occurs together with the larger and more elongate Anilara longicollis on the dead or dying twigs and foliage of fallen Eucalypt branches.

Host plant notes

I have collected adults from the dead foliage of a wide range of Eucalyptus species, and reared them from billets cut from fallen branches of Grey Box E. microcarpa in Adelaide. I also extracted dead remains of one individual from a dead fallen branch of E. microcarpa at another nearby site. A second larval host plant species was revealed by A.M.P. Stolarski who extracted two dead individuals in the SE Region from a stem of Ridge-fruit Mallee E. incrassata which had fallen over about 12 months earlier. It is expected that breeding wold occur in at least most of the Eucalypt species on which the adults have been found.
