The adult fly, which measures about 16 mm (5/8 inch), is a mimic, very close in size, color, and appearance to the organ pipe mud dauber wasp and its relatives. The mimicry of this particular kind of wasp is especially enhanced in that the fly's antennae are elongated and wasp-like, the fly's hind tarsi are pale, as are the wasp's, and the fly has two small transparent "windows" in the basal abdominal segments that make the fly appear to have a narrow "wasp waist". The adult soldier fly has no functioning mouthparts; it spends its time searching for mates and reproducing. The adult's life span is 5 to 8 days.
