Epalpus signifer is a widespread species, ranging from British Columbia, California, and New Mexico, east to Nova Scotia through Florida.
In many parts of its range, including West Virginia, it is one of the most often noticed Tachinid flies.
The other two species of Epalpus, E. albomaculatus and E. rufipes, are not found in West Virginia, and in fact are not found east of New Mexico.
Host species for Epalpus signifer are Pinion Moths in the genus Lithophane.
