Houdini flies are now in North America

First reported in New York in 2011, kleptoparasitic Houdini flies from Europe have now been sighted in Washington (state), which probably means they are in multiple states. Please submit observations if you see them lurking around your premises. This is a photograph of an adult at my hotel in Pennsylvania (2019).
