pe-taxon #11 (not Stenodexia sp.)
This is a really unusual tachinid with its mottled wings, shiny black body and long, curved piercing organ.
EDIT (05/11/2010): This was originally keyed tentatively to Stenodexia but I was not 100% convinced. Monty has since said that this is definitely NOT Stenodexia after all … so back to the drawing board! 😉
