I don't know what your triangular thing is called but it sounds like the bug i get on certain plants each year. They hop away, really far at times, if you attempt to squish them. I wonder if they're a type of leafhopper. They leave behind stuff similar to mealybugs, but aren't mealies. Their bodies are a medium brown if/when the cottony stuff isn't covering them. They like my citrina dayliliy, my hosta flowers and especially my buttered popcorn ranunclus.

You can move daylilies pretty much when you want if you can keep them watered reasonably after the move. I'd cut back the foliage to about 1/3 of the length or less to lessen stress on the plants after you move them unless you get tons of soil. That's the normal way to multiply or divvy them- dig up a clump, separate them & trim down the foliage. If you can stand to wait until we are getting more regular rain they'd do better.

thanks for your input!

The bug does seem to resemble a leafhopper. I'll have to check into that guy a bot more, I'm not worried so much about the biug as I am with the stuff he is leaving behind on the plant.
