I had that, and they were migrating down the trunk every morning. I used wide tape and banded the tree. end of caterpillars. Here is a link that might be useful: Duct Tape for caterpillar control

The first thing I try to find when I find eggs is a desirable butterfly, so searched aloe host plant. At a glance, that's doubtful. A search of "eggs on aloe" turned up a bunch of stuff about hair, a search of "eggs on aloe -hair" didn't cause a particular pest to 'jump out.' If this was my own searching, I would have been more thorough, spending more time, actually clicking some links and reading some stuff, but the impression of the 2 mins I spent on it was that it's probably something not a traditional indoor plant pest, but some type of outside entity that may or may not be a leaf muncher. These do resemble armyworm eggs, going by the preponderance of similarity method for looking at searched pics. If you investigate further, I'm curious with you. I've found a few armyworms, but no clusters of eggs like that. Maybe they come in singles/smaller batches too? ...and your plant looks like it's inside? So that's the longest way of saying IDK ever, I think, but maybe points you in the direction of finding out. The 'garden clinic' forum would be a good place to post this pic.

Sammy, Thanks. The number of hoppers has creeped me out this year. When I walk through the grass on the side of the barn, all I hear is "plink, plink, plunk" as grasshoppers rise from the grass in unison to avoid being stepped on and hit the side of the metal barn. Usually they peak in July and then their numbers start dropping, but this summer, since we were very dry all spring and didn't have good rainfall until June and July, we went into summer with a huge population, and then every time it rained, we got a new hatch of hoppers a few days later so it still seems like we have more every week than we had the week before. There's been a lot of cicadas at night---the whole loud "buzz" of all these living things at night is so loud that you can't even sleep with a window open on a cool night because they'll keep you awake. I saw a dead cicada lying in the driveway yesterday, so maybe their population is beginning to decline. There are some veggies in the garden that the hoppers ate all the way down to the ground, and I sprayed one time this summer with a chemical pesticide, or I think the hoppers would have devoured the entire garden. That's the first time I've ever sprayed my entire garden with a chemical pesticide. It killed the grasshoppers, but killed lots of beneficial insects too, so I doubt I'll ever do it again. I hated everything about it and think that in future years when the hoppers are extremely bad, I'll let them devour the garden and I'll just take up needlepoint or something for the rest of the growing season. We are at the point now where we desperately need for the blister beetles to show up in the next few weeks and devour tons of grasshopper eggs or we'll be in trouble in 2015. This is the first time I've begun actively rooting for the blister beetles to please show up here. Dawn

Different moths, different life cycles, different coloring, and different damage. Cutworms go for the stem at ground level, encircle it, and literally cut the main stem. So height isn't so much the concern as is direct contact with the stem so they can't wrap around it. Personally I use the disposable plastic soda straws stuck right up against the stem itself. I don't cut them in half cause I'm lazy at that so they are a good 10" or so with about 3" below ground. You could cut them in half and it would still be long enough I think. Some use the old 10 penny nails that are approx 6" long, some use stick or twigs. Some advocate toilet paper tubes cut in half but IME the worm can get inside them and still damage the plant. Dave
