@marknewton Is this one L. jonesae? I'm not familiar with the mallee scorpions.
On Baeckea sp. probably a pollinator, pollen on thorax
Beefly Exechohypopion species, egg-laying, Lake Lea, Vale of Belvoir, Tasmania, January 2023
Bee fly: Exechohypopion
Identified as Exechohypopion on Bowerbird by Tony D.: "Lovely looking beefly. Exechohypopion were until recently placed in Villa. The former is said to have a bulging face (which appears the case here) whereas the face is only slightly produced in the latter."
