Specimens of H. phoebeae are of similar size to larger members of Heterosternuta such as H. diversicornis (Sharp), H. wickami (Zaitzev), and H. oppositus (Say).
Specimens of H. phoebeae are easily distinguished from specimens of H. diversicornis because the former do not possess ventral pubescence between the metacoxal lines.
Ventral coloration of specimens of H. phoebeae is yellow to brown, while that of H. wickami is almost uniformly black.
Unfortunately, ventral coloration of specimens of H. oppositus varies from almost black to orange thus specimens are best distinguished from those of H. phoebeae by male genitalic characters. (Wolfe & Harp 2003)
