Those babies are the best...I had one in the "garden" the "X" planted on the south side of the house a few years back...you almost have the right dimensions on the shot of yours...one big sucka!!!
Our tomatoes and peppers were absolutely blemish-free. That thing ate and sucked up anything that landed in the "garden" and boy, was it big...and FAST!!!! Scared that crap outa' me when I first saw it and *POOF!* it disappeared!
If that thing's near some plants you're harvesting in a few weeks, leave him/her there 'til the final plant's picked.
Then...get out your baseball bat and hit one for the Gipper!!! (wrong sport!)
