25 July 2015: Observed an imposing figure of a Robber Fly (Asilidae) perched about six to seven feet up on a twig/leaf of a tree next to the Cicada Trail at the Lake Lewisville Environmental Learning Area (LLELA) in Lewisville, Texas. It was a striking sight from the point of view first observed from the Cicada Trail. Was unable to get front digital images and instead all three presented here were taken from a lower left lateral view. The canopy's light was intermittent at the point where the images were captured. The Robber Fly was engaged in grooming itself and ignored all else occurring around it. We have no clue as to the IDentity of this Robber Fly but it's being shared in case someone knows its given IDentity.

"Microstylum morosum - female 20 September 2014: Walked about at Rockwood Park, Fort Worth, Tarrant County, Texas, and came upon a very large dark brown and black robberfly with green eyes. Subsequent attempts to IDentify this robberfly led us to BugGuide and there Herschel Raney IDentified it as Microstylum morosum (female). As we recall it being said elsewhere recently on iNat, this particular robberfly is the largest fly to fly the skies of Texas. Our thanks to Herschel Raney of BugGuide and also Ken Woglemuth for overseeing the administration of our query to the site. We were only able to take one digital image of Microstylum morosum before it sped off and thus the images affixed to this observation all come from the one pic. The IDentity to this robberfly can be found here: http://bugguide.net/node/view/1142507 We've not returned to Rockwood Park in the past year but it may very well be worth making a return trip. Rockwood Park is administered by the City of Fort Worth, Texas.

Microstylum morosum Okay Levee Millwood Lake Howard Co., Arkansas 7 September 2007 Very rare in Arkansas, usually encountered in Texas and Oklahoma and other western locations. This was apparently the 2nd documented record for Arkansas.
