I don't know if this is an original film of the guy who did put it online and I think it's part of a bigger film but I liked it (in connection with our topic here!). It is about [I]Pseudacteon[/I] flies, how they escape from the pupae in the ant-heads and how they lay eggs on/in the workers. You can compare those flies with the wasps...
