Efferia [Nerax] aestuans female. Without question, this is the leader among robbers that like to land on my net. If I held out my net handle vertically and walked in the Ouachitas I was guaranteed to get Nerax perching on it.

Underside with bug.

Female who took down this Argia moesta right in front of me. She seemed to be haunting this beach edge just for the damsel crowd.

Females dominate my deck in late summer (painted red). This appears to be the first Soldier fly I have ever seen them take. Good sized prey. Looks like a Hermetia species.  

The small and fuzzy Nerax male. Sometimes literally half the size of the Pogoniefferia males.

Nerax male with a fine fly catch. Almost looked like a robber being eaten but I could not be sure.

Nerax male again with a lovely leafhopper at Camp. Always photogenic. I think the leafhopper is Tylozygus.

This is a male Efferia [Nerax] prairiensis. Previously the species was known only from TX OK KS but Norm has a population in east Arkansas that really isn't in a prairie environment. They can be outburst abundant. Note the single white band before the genitalia. And that orange and black leg contrast. Moved from Pogon group to Nerax.  
 

Female E. [N.] prairiensis. Paler overall that the above females with less dark on the upper abdominal segments. I think the ovipositor is more knifelike again than E. [P.] pogonias. Maybe quite a bit shorter than nemoralis or plena. 
 
Female from 2012 in Craighead again at the rejuvenated prairie patch at the park for Crowley's ridge. Norm is working his artistic side here.
