Robberfly - Efferia aestuans - female

Robberfly - Efferia aestuans - Female
Fort Bragg, Cumberland County, North Carolina, USA
June 15, 2005
First robberfly of the year...and I had to break into the construction site of my old bug hunting grounds to get it. Last year in that area I got one for every month from April to October.

Robber
Now NC isn't that far north...should have had quite a few robbers already. This is the Nerax aestuans female again. One of the playful ones that will land on you. Sometimes fearless. The males are much less common and harder to approach.

 
Nerax
What is the difference between Nerax and Efferia?

 
Efferia classification
Well, the classification of the large Efferia genus was split up in 1997 by the south American robber scientist (Artigas). The split is not accepted by everyone. Some wish to stick with the original large genus. So it is still fair to call them all Efferia instead of the multiple genera. But the E. aestuans fell into the Nerax group.
