My sister keeps finding these flies "stuck" to flowers in her garden, apparently dead. I'm wondering if this could be a fungus based on the whitish material on the abdomen in these photomicrographs? Any info. on the fly ID would be appreciated - my impression is a calyptrate muscoid fly - wing venation is a bit like Fannia?

Looks like a fungus victim to me...
Hi, Ken. I'm afraid I'm no help whatsoever when it comes to offering an ID for the fly, but I've found several of these flies "stuck" to the tips of vegetation around my place and definitely think they have been attacked by fungus. You might want to leave a comment here with a thumbnail to this post and perhaps Charley could confirm your suspicions..

Done -
thanks, Harsi - I wasn't sure if that forum was only for confirmed fungus-attacked bug images or not, but...
