i know. I mistaked, I realized immediately that was T. grossa, but this site is terribly unstable, so I last some time to fix it.
as you can see I fixed before you :P

Here's some babies from the same species. Took 14 days in captivity for the female to start laying eggs! The eggs hatched in few minutes and the minute larvae remain flat on the substrate until they detect some movement, starting franticly wobbling around. A bit like howerfly larvae do.
..Eventually found some use for the dozen Macrothylacia rubi larvae I had in the stock. ;) Mean, I know. One larva died quite soon, others are still fine

Great photos - got any more? :D Let us know about the progress of the larvae too - and take plenty of photos - this kind of thing is hardly ever documented :)
BTW, the tactic of laying eggs that hatch immediately and then wait for a passing larva is fairly common in tachinids. They don't have a hard ovipositor so they have developed other ways to get the host and get inside. Even the species with an apparent ovipositor really only have a "piercing organ" - a hard, stabbing tool which makes a hole into which an egg is laid. :)
