Egyptian Beetle (Blaps polychresta)
These beetles are native to Eygpt and Syria and are believed to have been introduced to Australia via European clipper ships carrying grain. They are common in the South of SA and in NW Victoria. Historically it is said that Eygptian women keen to get fashionably fat would eat these beetles.They aren't considered a pest but can spoil stored grain.
This exotic species occurs in southern Australia, where it occurs in semi-arid areas and is a trivial stored grain pest.
