Rainieria antennaepes is a species of stilt-legged flies in the family Micropezidae found in North America east of the Rocky Mountains. The name "antennaepes" means "antenna foot". They frequently hold their white-tipped front legs up and wave them around in a manner that makes them appear like the antennae of ichneumonid wasps. They feed on detritus, bird droppings, and similar waste.

Under 5% of wildlife watchers report a Rainieria antennaepes sighting in Washington on a given day, based on 104 verified sightings from GBIF citizen-science data. It is the 279th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to July

GBIF citizen-science records
It is estimated from how often the Rainieria antennaepes is recorded against all the insects logged in Washington (104 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
