General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
Like other Scoliid wasps, the females have short antennae, where as males have much longer ones.
We were surprised at the size variations of these. On Ellura we have found and measured two females; 18mm (S2) & 25mm (S3, not shown), found in Apr (S1), Nov (S3) & Dec (S2). Graham said "These wasps are scarab larval parasites and the size varies depending on the size of the host larva." In refering to separating out the 2 species, as listed on Atlas, he said "tasmaniensis in the south and radula in the north. The easiest way to distinguish them is in the colour of the setae on the top of the thorax of the female - it is mostly uniformly reddish brown in the latter where as it is yellowish in tasmaniensis. These hairs are often partially abraided in older specimens."
Perhaps the common name refers to the hairs, rather than the body colour which seems to be more orange. However, of the male images we can find on-line they all seem to be yellow.
