The other day I saw something I had never encountered before on one of my junipers. And a few days before that I saw a bunch on a hibiscus leaf in my flower bed. They looked like some kind of fruiting body of a fungus so I scraped them off.
After investigating later I discovered they were eggs for green lacewings, a very beneficial insect to have in your garden.
