Owlflies are readily distinguished from dragonflies because the latter have short bristle-like antennae. The closely related antlions (family Myrmeleontidae) have short, weakly clubbed antennae, smaller eyes, and very different wing venation.[1] All but one species of Ascalaphidae have long antennae, easily distinguishing them; the sole exception is the Brazilian Albardia furcata, the only living member of the subfamily Albardiinae, which has short antennae, but the club is very strong (compared to myrmeleontids) and its typical reticulate ascalaphid wing venation demonstrates its actual relationships.
