How do I determine the gender of Tachina grossa?

The usual things ... presence/absence of: large male genital capsule; long pulvilli/claws; and wide/narrows frons.

Ok, thank you.
I have one that is quite a bit smaller than the others and has a lighter colour on the head. I thought maybe it could be a male.

It's impossible to go on size or colour really - just check the features I listed and it should tell you :)

Yes, I should have added that with your help I see they are all females ;)
