Ligyra punctipennis
Bee Fly, Ligyra punctipennis, with a white bum. Mount Jerusalem National Park, Koonyum Range, NSW, Australia, December 2014.
This is similar in appearance to Ligyra bombyliformis.
However, from what I can see, in Ligyra punctipennis...
* Abdomen has first tergite black with yellow lateral hairs
* Second tergite wholly covered in yellow hairs
* Third and Fourth tergites with black hairs and scales.
* Tergites 5-7 have white scales and black hairs. (To me the fifth tergite is silvery black.)
* The black cross-bands on the third and fourth tergites separate this species from others.
The wings are yellowish brown close to the body and nearly hyaline away from the body towards the trailing edge. There are 9 small distinct dark spots at vein crossing points. There are 4 submarginal cells. The first posterior cell is open, its veins do not meet before the wing edge.
See Paramonov, S.J. 1967. A review of the Australian species of Ligyra Newman (Hyperalonia olim) (Bombyliidae: Diptera). Australian Journal of Zoology 15: 123-144.[133]. Note, in this paper, Ligyra punctipennis was first described as Ligyra contrasta.
