Any chance for a more detailed shot? How large are they?

I tried to take a closer shot, but cannot get enough focus. the biggest ones are approx. 1/4", they are black with a yellowish outline around its belly, and horn like hairs all over its body, they seem to attach themselves by their rear end. I see them all over the leaves but they also attach themselves around the nodes of the branches in numbers of 10-15. All my leaves have spotts on the, and I have lady bugs all over the bamboo. I presume that they are eating all the eggs that have be layed.

Thanks

What's your location? Is the plant inside or out? Any chance of a side pic?

I'd like to see a picture of the ladybugs. I am wondering if they are a different kind of beetle.

Anyway, I'm thinking that it's a beetle lavae of some kind. Some of the ladybug beetle larvae are very spiky, as you can see from the image of the squash beetle (a type of ladybug) in the attached link.

Thanks, Rhizo

The pict in the link, looks very much like the things that are all over my plants. Unfortunately I will not able to take pictures until the weekend.

If this is a beetle, are they responsible for killing my bamboo?

Thanks

Generally speaking, if a beetle is the kind that is interested in plants, then damage can occur from the adult and the larvae.

I suggest you try the Bamboo Forum, pronto. Be sure to let them know your general location. That is important information for the identification of insects and other pests.

I still want to see pictures of the adult beetle, out of curiosity.
