I posted about the same problem, and really only on my pears as far as tree leaves go. Mine's definitely a night feeder. I haven't done the flashlight thing, but judging by a nearby grape vine, I know I have cutworms there and apparently they can affect fruit trees! Who knew, lol? I'm treating for cutworms and I'll see if that does it. My pears are young (not many leaves/branches) and begin branching low to the ground, too. So cutworms could make sense in my case. I don't know if that helps you any, but maybe so :)

Agree with the snails/slugs as the most likely culprit. And Sluggo will work very well, and is safe to use for your strawberries. Believe me, if you think you're upset about the leaves being eaten by the snails and slugs, just wait until they ruin the fruit! Lay down Sluggo in a 2 to 3" row all around your strawberry bed, and sprinkle throughout the bed. You can also use Sluggo Plus if you're also having earwig problems, great new product! For a non-organic solution, Corry's makes a liquid product called, "Deadline" which is Metaldehyde. Normally, in pellet or bait formulation, you don't want to use this if you have dogs or small children, but in liquid formulation, you can lay a line down around the perimeter of your strawberry patch, and if a snail crosses it, it will die. You'll need to reapply if it rains. Strawberry patches are an ideal place for snails and slugs to hide out, so you really also have to hand-pick them out in the evening or early morning as well, to get the population down. We are having a snail, slug, ant and earwig explosion here in California, due to all the rain we've enjoyed :-( Patty S.

I have posted some photos. Sorry they're not clearer. My camera couldn't focus on the caterpillars. Here is a link that might be useful: Photos of caterpillars -sorry about the quality

That is damage from slugs and yes they are usually only seen at night with a flashlight. They are quite small and during the day they hide in the leaves and mulch around the base of the plants and on the undersides of the leaves and crawl up the leaves at night. There are a number of slug treatments available that you just sprinkle around the base of the plants to kill them. Or you can go out at night and hand pick them or sprinkle them with salt. Just pull up the discussions here on slug control Dave
