Now that dog day cicadas are out in full force, their giant wasp tormentors have emerged to gather the bounty. Female cicada killers (Sphecius speciosus) scour the trees for prey to fill their underground burrows, while males jostle for the territories that grant them mating rights.

Sphecius speciosus, male

Several male cicada killers have set up shop in our prairie garden, perching alertly on the flower heads and zooming off to challenge would-be usurpers.

The above photograph, taken in ambient light, was possible because of a thin overcast at mid-day on Friday. The soft lighting eliminated any glare or harsh shadows. As I abstained from my usual foreground flash, the background (mostly Rudbeckia black-eyed susans) was naturally exposed in full color. Light levels were bright enough for a moderate depth-of-field (f/7) at ISO 800 and a fast, 1/200 sec exposure.
