Please post a picture. It does howeever sound like caterpillar egs. Swallowtails tend to lay their eggs on passiflora species if im not mistaken

Thanks for your input! I'm going to look up pictures of the eggs of the possible butterflies we have here to double-check. But in looking for a picture (my cell phone camera is kaput), I keep running across stink bugs.

The eggs on my almond look just like these (better link later, too):

We definitely have stink bugs in large numbers. Apparently they found the orchard.

I might have to do a separate post, but if anyone is reading this and knows an IPM approach to stink bugs, please give a shout.

My go-to insecticide is Spinosad because it preserves the beneficials well, but I don't think it works well on stink bugs.

At least I can get the eggs off the trees, though! My trees aren't very big yet :)
