That caterpillar is far too young for me to make a stab at guessing what it might be. It's not a wire worm, though. You can see the true legs and the prolegs in the top picture. I sort of doubt that it is a tent caterpillar, since they tend to stay in their webby nest while they are still that teensy. So we DO know that it is a caterpillar eating your veggies. I'd race over to your nearest garden center or gardening department of a big box store and locate some Bt (Bacillus thuringiensis var. kurstaki), which is a biological agent used for the control of caterpillars and only caterpillars. You can purchase Bt as a dust or a liquid which can be mixed and sprayed on your plants. I suppose that many manufacturers produce Bt commercially, but Dipel is a brand of dust and Thuricide is a liquid. Bt-k is a bacterium that exists in nature, but has been 'harnessed' and used to control caterpillars for generations. It is an organic product. Bt-k controls ONLY caterpillars but is best used when those little pests are very small, such as yours.

Maybe a few slug holes but nothing to be concerned about unless it gets substantially worse. The damage is all on old growth and that is often just environmental, not pests. Did anyone mention to you about reducing your pic size so they fit message boards? Go to approx. 600x400 Depending on which service you are using they usually provide an auto reduction for you to use so you'll want to check in to it as these are a bit too big for many to load without distortion.

If I'd known this was going to be salad size April 24 here I wouldn't have ripped most of my plants out! i can't believe it survived our past winter. The seeds I planted are just now sprouting. But the spinach ready to be in my salad - were planted from seeds a year ago. Apparently it is a perennial. Live and learn- Karen

Since you're not getting any response here, I'd post this question in the organic forum (if you haven't already). Here is a link that might be useful: Organic forum
