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.

Rare
Under 5% of wildlife watchers report a Rainieria antennaepes sighting in Chicago on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 379th most-seen of the 978 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rainieria antennaepes in Chicago on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Rainieria antennaepes sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 11
Of the 11 cities where we can rate Rainieria antennaepes sightings, Chicago ranks 9th at under 5%. The best odds are in Boston (United States, about 10%), Washington (United States, under 5%) and Philadelphia (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Rainieria antennaepes is recorded against all the insects logged in Chicago (25 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.
