Need (pest?) ID help...

Mowing one of my lawns today I saw a black spot in the grass.. just a couple of inches wide. It kinda took me by surprise.. At first I though it was spray paint or something.

Anyway.. it looks like bunches of little eggs attached to the blades... they are black

Anyone know what it may be?

Thanks
