Something has been munching on my daylilies for about a month now (they've been in my garage over the winter, so I know it's not slugs - I figured it's aphids and I've been spraying with dishsoap and water once per week). I moved them outside last week to enjoy the weather, and when I brought them back in (frosted last night) I noticed these guys. They're everywhere! What are they and could they be what are chewing on my plants?
