Worry.... I saw one a couple months ago and I just picked it off and let it go and they ended claiming several prime O's off the best buds. But I just did a butane run with it after cleaning it up. Just watch for premature brown patches on your buds and they eat a hole right along the stem so you'll get patches that are dry and fall off when touched. Pull the buds away from the stem untill you find the bugger clip that top of the bud off to stop any other damage. Dry it super dry and tap it to shake all the poop out of it. Than get a couple cans of butane and do it up.
