Keep a sharp eye out for bugs. It really helps in figuring out the most efficient and appropriate treatment to find the culprit. As a Master Gardener, I have been hearing a lot about insects, mostly 4-lined plant bug currently. The wet weather has been good to them, as well as fungal diseases.

The U's Extension Service has a very good diagnostic site--see link below. Good luck saving your hepatica!

Thanks for the tip. I did a complete search under all the leaves and found a green worm/caterpillar. Since then no further damage!

Thanks again!
