Last week my late corn took a beating very similar in your pics and I figured that it's either early morning squirrels or late nite raccoons. I surrounded my plot with nylon netting but the varments were still getting into the corn chewing thru the nets and eating the pre-ripened ears like peeling bananas. I was wrong on both varment counts. I placed a large hav-a-hart trap in the middle of the corn plot (with ear inside) and the next morning I had a skunk in the trap with an ear eaten to the bone. I knew that skunks were stealing my grapes but apparently they love Ambrosia sweet corn too.

I hope you don't mind a few more observations... First off, I was going by the numbering at the top (16 of 44, for instance) and didn't see the numbering at the bottom until now, so several of you labels are off. Sorry. The numbers I've used below are your labels. :) 2 could be strawberry or mock strawberry, or maybe something else 4 is a weed 5, 34, 36 and 41 could be Echinacea or Rudbeckia, or something else 7 might be a milkweed, snip a bit of leaf and see if has milky sap 15 could be Jupiter's Beard, Centranthus ruber, it will have salmon pink flowers very soon if it is 17 could be Valerian or Peony, or something else 18 is extremely cool and I would love to know what it is, I hope someone will recognize it! 19 could be Moonbeam Coreopsis 20 might be Hydrangea 23 is a grass that has volunteered in the middle of your lily of the valley 24 looks like Goldenrod, Solidago, to me 25 is a weed 26 and 35 might be Veronica 27 and 28 might be weedy honeysuckle, Lonicera 38 could be a Centaurea montana seedling 40 could be Rudbeckia (a different kind than the others), Plantain (a weed), or something else 42 the plant in front is a Hosta, the ones behind could be Dame's Rocket 45 could be Dame's Rocket

Could be a beet armyworm or corn earworm, or European corn borer. Here is a link that might be useful: Green Bean Pests in Texas

Agree - I would think rats or squirrels are munching on them. I've had mocking birds pick at the plants, too. They are just darn mischievous! Here's a thread with the woes of battling the munchers and some interesting video posted down the thread. http://forums.gardenweb.com/discussions/3889765/help-the-squirrels-are-eating-my-succulents?n=57
