Bless, greenhaven! you're actually trying to figure out if that bad muncher is worth keeping in that it may turn out to be some butterfly! Well, hope someone can help ID....

Speaking of which Greenhaven, I saw a beautiful dragonfly (must be thriving because of those mosquitos) and a few delicate and pretty butterflies (I love their blue spots and patterns)in my garden. I do have to admit their larvae may be contributing to the holes in my leaves besides that annoying grasshopper that I keep chasing with my hot wax pepper spray when it gets closer to the perfume zone. But at least they leave my blossoms pretty much alone; they're the only things I care about in terms of holes.

Don't you just love those little 'inchworms'? Also called spanworms and geometers; many of them disguise themselves as twigs. All caterpillars are plant eaters, so you need to decide if the damage is worrisome to you. Remove the culprits by hand and toss to the nearest robin. The adults of spanworms, etc., are moths rather than butterflies, by the way.

The other insect is the nymph of the green stinkbug. Bad.

Bummer! Squish the cool beetle. Check. :o(

There are nymphs in another true bug family that sometimes resemble stink bug nymphs, but even so I suspect rhizo_1 is right about that being a stink bug nymph, and rhizo_1 is totally correct about the caterpillar. It's without doubt an "inchworm" (ie. a species in the moth family "Geometridae"). All of them are shrub or tree pests when they are caterpillars.
