Within the Asilidae, Megaphorus species are characterized by their substantial body size and predatory . Identification to species level requires examination of specific morphological features such as facial mystax arrangement, leg spination, and genitalic structures. The species name "megachile" may indicate a resemblance to or upon bees of the genus Megachile.

Nomenclatural note

The specific epithet "megachile" creates potential confusion with the Megachile ( Megachilidae), but Megaphorus megachile is definitively a fly (order Diptera, family Asilidae) and not a bee (order Hymenoptera). This is a case of homonymy at the epithet level only.

Taxonomic history

Originally described by Coquillett in 1893, this has received limited modern taxonomic attention. The Megaphorus was established to accommodate large, distinctive robber fly species previously placed in other genera.
