Microstylum morosum

Microstylum morosum
Ft. worth, Tarrant County, Texas, USA
July 11, 2010
Size: 45 mm
Largest Robber Fly I have ever seen. The emerald eyes were glowing. Photo on the Ft. Worth Nature Center & Refuge. First time I have ever seen this insect. Any comments or observation would be appreciated. Male/female ???

Microstylum morosum range
Does anyone know the range of this Microstylum? In addition to this one seen by Troy Mullens at the Ft. Worth Nature Center & Refuge, I have seen it in the gardens of the Botanical Research Institute of Texas (BRIT) in Fort Worth and along the Trinity River floodplain in west Fort Worth. I had not previously seen this species in Texas. This one does not look exactly like the ones I have seen. Could this be the other Microstylum species?

July 14, 2012 Additional sightings
We saw 3 more of these on a Nature Walk on the 14th.
I couldn't get closer than about 15 feet for additional photos. Drat!!!

Appears female
My TX shooter friends are sending shots of both species of Microstylum down there. They are in peak abundance now I presume. And they are one of the finest insects in the southern US.
