This was larger than the owl flies I typically see in the Austin area in Texas. No idea of the species if indeed it can be identified from photos.

Owlflies are dragonfly-like insects with large bulging eyes and long knobbed antennae. They are neuropterans in the family Ascalaphidae; they are only distantly related to the true flies, and even more distant from the dragonflies and damselflies. They are diurnal or crepuscular predators of other flying insects, and are typically 5 cm (2.0 in) long.
