Over the last few weeks my hosta garden (over 500 different) has been invaded by these awful black beetles. I would smash them and they would merely walk away with their guts hanging out. surely they aren't indestructable Angry

before I had my shoulder surgery I would stand out there and pick them off and smash them between my fingers (with gloves on of course, ewww) They would be everywhere, on one plant and none on the next. they seem to prefer the all green ones, but they are moving on as they demolish the green ones. they first leave them with lacy curly strands, and then nothing is left but stems. then they move on. however, they seem to be on a lot all at once now that I can't lean over and pick the dang things. besides there are thousands and probably a half acre of plants.

Their droppings are all over and most of the time they come in twos connected you know where. they are eating machines and breeding fast.

I have never ever seen them before. My daughter who lives in Indiana, told me she has them too and had never seen them before. she doesn't have hostas, but she says it is eating her roses and dogwood trees.

What are they????? Grumbling Grumbling

By coincidence, somebody posted about blister beetles on the Midwest forum, so I searched and found this: http://en.wikipedia.org/wiki/Blister_beetle

I think they could be your bug.

Posted this on DG too...

Apply an insecticide to kill any remaining blister beetles. Avoid the temptation to wait before using an insecticide. These insects act so quickly when consuming your plants that the sooner you use an insecticide, the quicker you can save your plants. According to Oklahoma State University Cooperative Extension, approved insecticides you can use to kill blister beetles include Sevin and Thiodin. Organic options include natural chemicals such as pyrethrum and rotenone, according to the National Sustainable Agriculture Information Center. Follow the product directions carefully to ensure that you kill all remaining blister beetles.

Those insecticides will kill good bugs too so use with caution...

I would be out there as soon as possible with the Seven. Sometimes, chemicals are the only choice.

Kitty, did you feed them some Seven on the hostas they were munching on?? You know a spoon full of Seven helps the hostas go down!! Smiling (done in my best Mary Poppins' voice). Rolling on the floor laughing
