We suddenly found lots of tiny brown creatures on our grapevine.
We live in Dallas,Tx.
What those can be?
Are they harmful?
The branches look completely brown of these little dark dots.
We saw some bugs looking like lady bugs around, are they related?

They look like aphids, they'll be feeding on the sap of the plant. The ladybugs are there to eat the aphids.

Hi Waveguide, the insect in your first photo appears to be a Lady Beetle/Lady Bug, a good one. The others appear to be Aphids which are sap sucking insects that the Ladybugs eat!

Hosing them off with water is the best way but you still probably won't get them all. So, if you are willing to let nature take its course and let the ladybugs eat the left over aphids, they will. Thumbs up

Thanks so much for your responses! I thought that growing a grapevine would be easy ( and it was for 3 years), but now all this unexpected entomology​ serves a good example why agriculture - even on a small, hobby-like gardening scale - is hard! Earth is a very interesting, very confusing planet...

So true, Waveguide. It's a never ending learning adventure. Smiling Do you see any ants around? I find that often, where there are aphids there are also ants. The ants will actually farm the aphids for their honeydew, but that's a whole other story...

Another way is to fill a spray bottle with water and a squirt or two of dishsoap to spray on the aphids which will kill them.

Last year I had an aphid invasion on all of my tomato plants but then the ladybugs showed up and took care of the problem. You can read about it here if you are interested. The thread "Tomato pests and ladybugs to the rescue!" in Pests and Diseases forum
