They can also carry prey to a perching site using their powerful bristly legs.

A paper published in the Zookeys journal cataloged four genera of spider flies in Australasia. These species are specialized in parasitizing funnel web spiders, tarantulas, and trap door spiders. These species can be found in Asia, New Guinea, and Indonesia.
