106 Ascalobyas albistigma (Walker, 1853) An Owlfly

Ascalaphidae - Wingspan: 90mm.
Well, the Leaf-Cutter Ants are large here, about 15mm long, so I assumed that their predators, Antlions, are proportionately sized as well, but there was some uncertainty because of the antenna shape.

My thanks for help with this identification correction to Ben Price, PhD, Curator of Small Orders, Department of Life Sciences, NHM.
