STRAYA ... Each of these spiders are probably 2-3 inches or so in size, certainly as big as a decent sized huntsman. You can an idea of their size when comparing them to the leaves, and also the transformers on the power pole.There are dozens and dozens of them sitting above the tree line, and there were a lot more under the tree line. Most of the webbing was above the tree line and attached to the power lines, and spread across a good 10 meters or so.Makes for one helluva spider trap, maybe they're wanting to catch bats or birds .... so long as they stay up there, relatively harmless to humans
