Just wanted to see what this would be called and if if’s poisonous? I got a short 3 second video of it as well before it crawled down past the wipers into the hood, but it won’t let me upload that. Found 2nd picture online with no description but close enough match far as I can tell.
Panola County Texas spider identification
Based on the 2nd photo this specimen would appear to be a crab spider (Family: Thomisidae). The only poisonous spiders in Texas to my knowledge are the black widows and brown recluse species complexes, of which this particular specimen appears not to be. See this Extension publication for more information from Texas A & M (http://counties.agrilife.org/colorado/files/2011/08/spiders_23.pdf).
