I've been looking at 5am & evening. Either its happening in the middle of the night or during the day when I'm not home. The damage is extensive but random as to plant type and location in the garden (it's 100ft long) and since the pests aren't present on the leaves, that's why I considered beetles as my primary suspect. They can come & go irregardless of time of day.

Ahhhh, the lazy part - been there, do that too! Dance With Me - I've heard it is hard so I never got it. Earth Angel - grows like a weed, love it. Ice Age Trail - I had it, got it as a young TC and grew it in a pot but it didn't survive this spring. I've seen pics of IAT purchased from Jim's Hosta that were big and gorgeous. It also is a streaker plant and will produce other streaked plants from seed. If you get it, save me some seeds. Touch of Class - gorgeous, don't have it but have one of the look alikes named Dream Weaver. It does very well here and intro'd by Kevin Walleck, our current AHS prez. Jewel of the Nile - another KW intro and it grows like a weed here. Paradigm - a classic, yes to it. Liberty - a new one for me last fall. It almost didn't come back and when it did was puny. I dug it up and potted it - the leaf is 1" and probably won't make it back next year. I replaced it, it has only produced one new leaf - I hope it comes back next spring. Liberty is a sport, probably tetraploid of Sagae. I highly recommend Sagae for the look, the margin just isn't as wide. I don't have any of the others and have heard nothing about them. For a balanced hosta garden, make sure you bring in solid colors to offset the patterned cultivars. I didn't because I love all the same type. I then had to go back and bring in some solids and to move things around to please the eye. It is the same as the daylily addiction - we bring in our favorite colors, look around and it becomes blah, so we then bring in other colors to liven things up. Some good blues in different sizes I recommend - Abiqua Drinking Gouard or Love Pat - great color, upright growing. Small blues that hold their color late into the season - Blue Jay and Fragrant Blue. Dark greens - Fried Green Tomatoes, a couple of Lakeside plants that I can't remember right now. If you want big, try some of the sports from Sum and Substance - Sum It Up, Bottom Line and Sum of All. Big, fast growing, all with edges but not "clashy" edges. They are all dark green. Other must haves - June, Paul's Glory or St. Paul. I know you don't like the skinny leaves but consider Ginsu Knife, has a slight light margin but lots of rippling on the edge, Marilyn Monroe, lighter green with ripples and Queen of the Seas, big blue with ripples. These offset the big round leaves that I love. For golds, Choo Choo Train, Sweet Sunshine, I think, hybridized by Solberg and a couple more Lakesides I can't remember, really make the shady areas pop. Have fun as another addiction starts. Could I also interest you in orchids?????????? Brooke

More than likely a bird.

If these holes are located in an area that has been dry as dust for a long time, they might be caused by an ant lion insect (which google). The insect is a predator that waits, buried in the bottom of the hole for another insect to enter and slide down to the bottom, where it gets munched by the ant lion. hortster
