Oh yeah, Fort Worth, TX. Common St Augustine. Water weekly or so and strive to put down an inch each time. Fertilized with some 10-10-10 that I found in the garage in late May. Soil is sand and a bit of silt with lots of organic matter added in the form of chopped fall leaves, homemade compost and alfalfa pellets occasionally. My neighbor on that side uses pesticides, but I have not since we had the chinch bugs in 2011.

Not sure I noticed the actual chewing damage on the grass blades, but I've had whiteflies on my St. Augustine. They were on my hedges (a lot), and hung around the grass on the perimeter of my porch. Probably b/c that grass was lush green. When I treated for mosquitos (using a backpack blower) I just treated the small lawn area that had the whiteflies and they were gone after a day. This happened twice over the summer.

I've had white flies in my lawn for 25 years but never saw any damage. I only see them when I mow at dusk with the sun shining at an angle. I figured the chances were they were beneficial and not a pest.

We would get them throughout the day. Couldn't use the screen door without them blowing into your face. Pretty annoying. Still, never saw grass damage though...

Yeah white flies almost wiped out my Bermuda seedlings on my golf pad a few years ago, they only chew on the new shoots. They're attracted to CO2 so they will chase you & get in your face. Easy to kill though!

I think we're talking about a variety of different insects.

I'll get some photos when the shade hits that side.

nothing like examining extreme close ups of the grass to see other issues. Please don't send the blade sharpener police to my house :-) My lawn generally looks good to me, these pics indicate that it's not as healthy as I had thought. I have two big dogs that romp through the area a lot, hence the bare patches. I was unable to see any of the chewing damage, apparently it was on the part that I mowed off or I was experiencing a flashback from the 70s.

Now I'm thinking maybe eggs and nymphs maybe.

Did you actually see them flying off the grass blades? Any chance it is slime mold?

No, I saw nothing flying. I have whiteflies on some shrubs and know what they are. I am leaning toward grasshopper eggs now. That would explain the chewing damage on the long tips of the grass that was mowed off and the small 'seed' looking things.

I really don't see any slime mold. Thank you all for your replies.
