Insects
Hi cefi, You can tell what kind of insect ate your sage by looking at the shape of the holes and extent of damage. If the whole leaf and adjacent stem is gone, caterpillars plague your garden. If there are oblong, oval-shaped holes in the leaves, you have beetles. Try to identify the beetles. Worse case, you might have Japanese beetles, a rather invasive species. These beetles have green heads and brown bodies. If the plant is gone (stems, leaves, everything), then you have slugs and/or snails. If I am remembering this correctly, you can attract slugs and snails with beer, then you can kill them with salt. On the other hand, it's probably best that you seek a non-aggressive means of defending your garden. Good luck!
