While in Missouri bug hunting, my bro and I stumbled across a grasshopper that had just run into a widow web. Sure as daylight, the next thing we see is this MONSTER 2" L. mactans come shooting out from under her rock and start instantly immobilizing this 2" grasshopper. It only took about 10 seconds for the widow to completely subdue her prey. Here is a short 15 second clip of the HUGE widow in action. I was standing about 4 feet from the widow and her web, as it was shared with 3-4 other widows.
