Bold Jumper spiders
I only learned about this species this year. Just like a car that you recently bought, now I am seeing them everywhere. I was particularly happy to see they're willing and able to tackle a Brown Marmorated Stink Bug, since those are grapevine sapsuckers.
Grapes are vigorous, to understate the case, they can lose a lot of sap without noticing. But as a farmer you want to know there are limits to how much sap sucking is happening. Now I know.
